I wanted to break this off since the other topic was looking to be mostly about the LCD's

I wanted to see if the blank sockets on the system board were active. So I grabbed my multimeter and tested each pin to see if any delivered power. I don't know if these sockets are controlled by software, but it looks like these sockets are inactive.

I'm an electronics tech (avionics really) just so you know my background, and I am by no way a programmer i just hack my way throught when i need... poorly at that. I'm a long time reader but don't post much.
I havent taken mine apart yet, I bought it for the wife to use as an ereader she was using her evo before and already has bad eyesight I just dont think reading on that small screen is good for her. However we planned on returning it today because she couldn't get anything to work... But i loaded VAGAn-Tab rom on it and she likes it ALOT more now, but we still might be returning it (she thinks it to big and heavy to hold). So all I have to work with is the internal pics posted by other members and I thank you for them!
I was thinking about using a mini pci card with 3g/4g and GPS to solve my problem like this one for Sprint Customers looks very nice and they claim android support. Could someone please verify the length available for the card from the socket to the mounting holes? It should be around 50mm but i cant tell from the pic.
I cant post a link so google

M600_datasheet_v1.pdf
Then after more research I figured out that think I can get the GPS to work on the board. I found that the RXM-GPS-SG-T looks to be the exact chip they are using, the pin look to match exactly VCC, GND, RX, TX, RF, VOUT. So they are using an active GPS antenna (but could be modded for passive). They use NMEA-0183 or SiRF Binary output selected by a serial command. So we need to figure out if the TX is going to U39 making U39 the interface to the unit, or directly to somewhere else (idk need to see board) I hope i can attach my pic i made or maybe an admin can post it for me.
However the PCI slot might be just as hard to use, the pin 20 that has 3.3v isnt what we want, but it could be a software control to disable/enable the card. However we still need A+ on pins 2,52 (3.3V), 6,28,48(1.5V) and maybe 24(3.3V Aux) dependeding on the card. We could be dealing with a "Non Standard" connector, they are out there but most OEM's dont bother with them. More likely to find them on a Asus product ect. It's common for the SIM card to be powered by the PCI card itself and the board looks wired that way. I have 2 Digi International Mini PCI express Wifi/Cell Development boards and thats how they both power the SIM card. Pin 16 should goto Pin 1 on the sim card, 14->2, 12->3, 10->6 but maybe 7 or 8.
Getting the Power to it could be software or hardware. Looks like around U8 on the frontside could a Vreg setup, Or it could be as simple as putting in some 0 ohm resistors around R15 and R14. We also see that U7 is unpopulated on backside. So that leave us with U7,U8, R15, and R16 which could mean they are all part of the same circuit if they laid it out with any logic. TP1,2,and 3 also make me believe this is true, however they match up to LED_WPAN#, LED, WLAN#,and LED_WWAN#. I sure wish they match the power input pins, but that means all those missing resistors could just be for unpopulated status LED's. Like I've said over and over i cant tell ya unless i can probe around the board.
As far as the memory, yes its possible, I do BGA replacement at work. What I am afraid of is that the other memory chips look to be exactly on the other side and I'd be afraid of messing them up. I'd have to look at my jig at work and see if I could set it up without any problems.
I'm no electronics expert but I dabble. I'd be interested in internal GPS and a memory boost. I'm pretty confident in my soldering skills and would try something if directed by someone smarter than me.
This is something I am very interested in. Any new info on this?

I sadly no longer own a G tablet, wife thought it was to heavy to read books, and hated the screen. I cant argue with her on either of those points, so we returned it. However I got the ok to buy a referb on if i can find one, but when I did at my local store i showed them the paper and they told me they dont sell that stuff there and send me away. I talked to 3 different people too basically all told me to go f off. I even tried another time with the 7" they sell same results. I dont know why it gets listed on the website if they wont sell it.
Not to get sidetracked, but i even did by the proper bga fittings to solder the ram chips too lol..
So no its probably not going to go any farther from my stand point, if anyone wants my help I still read the forums everyday.
I'm just gonna wait and see what comes out in the future that XDA gets behind, because I'de never buy anything that didnt have an active community here.
IF you were looking for a reader fo rher mainly, you should've really gone with the Nook Color... eInk devices are good too IF you don't really need good PDF support and/or need it to read more complexly formatted documents, e.g. technical manual, mathematics texts, etc. i.e. eInk is best suited for ficiton and other simply formatted documents, but it VERY readable except in poorly lit conditions where you'd need external lighting of some sort.
Very true I should have bought her a nook, but now she doesnt want it because its not powerful enough for her needs imo. She also wants to login to her school (blackboard) and be able to use overdrive. Plus she likes dungeon defenders and I dont think that can handle it. We are just gonna wait it out and see what comes along, mostly cause we have our first due next month, so trying to be frugal.

Yep, you'll want a full blown tablet then and I suspect that the NC would be too much of a bother to get setup for her for what she wants it for...
All the 10" tablets are fairly heavy too, so you'll probably have to stick to looking for 7/8" tablets and I suspect Tegra 2 or multi-core cortex-a9 SoCs from other mfgs... not much in the way of 7" ATM other than the elocity a7 (was c. $300 around xmas), but it's not very hacker friendly and I don't know if they ever got the USB port to run in non-host mode... probably best to not even look at it...
The g Tablet would, as many have already said, be a great tablet if it had gps mainly and increased memory. Adding pci-e would be even better. I would be extremely happy with the addition of gps. I would be very tempted to allow somebody with expertise and high level of confidence of success to experiment on my tablet.

Just bought my Gtab yesterday. As you know the stock Roman/UI sucks big time. I installed Clockwork followed by CyanogenMod 7 and what a difference. Anyway I looked on the web for a dock and it seems there is a Chinese version of the Gtab that has higher spec's including GPS. It would seem logical to assume the U.S. motherboard has the same circuits built in. Who knows what's possible....
It's too bad that more people don't feel like tearing up their electronics to start soldering things to them.
Hi, i just got my transformer and have no idea how to charge it up.
the charge came with a section for the usb to plug into, then a second section which has the plug on it. I cant get these bits to fit together at all, they keep falling apart, and when they do decide to stay i don't get any indication that my tablet is charging. I also plugged into the usb into my laptop and the charging indicator still didn't appear.
Any help is appreciated, thanks!
the 2 parts of the charger snap together, at first I thought I had mine together but got the same result you're experencing. You have to put the 2 parts together till you hear or feel the snap,I had to apply a fair amount of pressure to get the 2 pieces connected. It's not you, the charger pieces are just really a snug fit and need a bit more force than one would think to get them connected.Once you've got it connected you'll know as you'll feel the difference immediately. Hope that helps.
Thanks for the help, they snapped together after i put quite a lot of force into it, it seems to be charging now, thanks!
i had to initially push past the point i thought i'd break it in half to get the two pieces joined together.
I actually thought my charger was defective when I first tried to assemble it. It just wouldn't go in.
Finally after 2 weeks of trying here and there, it snapped in. Good thing (actually not a good thing) that Asus Support is so unreliable because they still haven't shipped a replacement adapter.
Guess I should cancel with the Asus RMA but I'm not even sure if they were ever going to send it...
Anyway, the adapter is really a bad piece of hardware: it felt like I was going to break the damn thing at times. (I guess it isn't as widespread or maybe some people were luckier than others because I haven't really seen a huge commotion about it)
For those that aren't sure why their tablet isn't charging then this is probably why.

So it's a bad piece of hardware because it doesn't break when strained and connects very securely? Wow your view sure is skewed. Yes it's hard to press it into the other piece, how is this a bad hardware problem?
i won't use such complicated transformer . too complex . quit to use

Because had I actually broke the damn thing, I would be liable for damages. It's still plastic so it is still breakable. Plus, the metal part is bendable given enough pressure.
Did you even think that maybe they should have made a one piece for the adapter to begin with? Or at least assembled it at the factory so that consumers don't need to deal with it at all?
Second, I shouldn't have to spend an exorbitant amount of time figuring out why this thing wouldn't connect. Where in the manual did Asus say you needed to apply a large amount of pressure? In what other electronic device/adapter do you have the same amount of difficulty assembling the device?
Remember, if you break this thing, then you have no way of replacing it without buying a new TF because Asus's support is that terrible. (I am not the only one who can testify to this)
Maybe it is a feature for YOU; but having adapter assembly difficulties is not something that I would consider as "good hardware". Excuse me if I don't want to ruin something I just spent $550 (tablet + dock) on -- especially since I have no other way of charging it besides the extremely slow USB option.

But you didn't break it. Because it's built well. It doesn't say large amount of pressure but it does say how to assemble it in the manual. Besides my HTC charger is made in the same fashion, a little easier to assemble but it's done to reduce production cost and make it easily adaptable (hence the 100~240v range) by more than just Asus.

I may not have but what if someone broke the adapter because of the difficulty, then who is to blame? And when I said it was a "bad piece of hardware", I meant the design, which is an integral part of any hardware. (also, just because something doesn't break, doesn't mean it was built well. But, that is another issue entirely) I don't want to feel that I might break something that I invested a large sum of cash in. I am not the only one that felt that felt like they were going to break the adapter. Some people are even afraid to disassemble it because of the frustration they dealt with when putting it together in the first place.
And where in the manual does it say how to assemble the adapter? You mean that one picture -- with no words at all -- where they draw an arrow in between the two parts? Yeah, big help -- like if I couldn't tell in the first place. They don't even tell you that you need to push it in all the way. The first time I tried, I pushed it in half because it wouldn't go deeper. How was I supposed to know that you needed to apply much more pressure? Also, how do costumers know if their device is defective if there are no instructions and assembly is more difficult than should be?
Again, assemble it at the factory or make it a one piece. Do you have a source for production costs? I find it difficult to believe assembly costs would be that much higher if they had just put it together. This isn't like plugging in the USB cable where everything is a nice and easy fit; it was way too frustrating than it should have been. Asus probably saves money from having to deal with consumers complaining about the charger if it came ready to use.
To me, hardware depends on the experience and that includes assembly. I don't want to worry about whether or not I might break it. (it is just an adapter, it shouldn't be this troubling!) I have never had an HTC adapter so I can't speak for that but I have never had trouble with adapters before. All companies want to save money but I don't have difficulty with their adapters. It's ridiculous that I have to talk about the adapter since with every other device/company, it is a non-issue. Again, the worst part is that you have no backup option besides buying a new TF to get a replacement adapter in case anything goes wrong.

Or you could, you know, buy a new adapter.
Besides, I've not seen a single report of a broken power adapter because they tried to assemble it so your complaining about something that hasn't even happened and will unlikely happen since it's obviously made to take the strain if thousands of people were able to put it together without breaking it.
Personally I feel secure in the fact knowing that it's well built and wont come apart easily like other similar style chargers I have seen, but I guess pressing 2 parts together is a giant issue which is nearly impossible to do and oh god, you might even break your nail!
And yes paying a bunch of people to click 2 parts together is quite costly.

Where do buy a new adapter for this? I've been waiting for one since I got mine a while ago. The cord is too short, the power adapter shakes around in the wall socket, and you can't buy an extra charger because no one makes them except for Asus at this point (and even Asus doesn't have them to buy separately at this point).

Buy a new adapter... Have you been reading any of my posts? Okay, sell me yours for market price. There aren't any for sale if you haven't noticed. And no, I don't count waiting a month for a pre-order as an option. If you're willing to deal with one month of charging it through USB alone then by all means, give me yours.
Frankly, if I broke a nail then yes, it is badly designed. Not sure why you think that adds to your point.
"And yes paying a bunch of people to click 2 parts together is quite costly."
And you know this for a fact because...? I asked for sources and you give me, "trust me, I know." Do you even realize how much they pay their factory workers in China? (Apple factory workers get around $1 an hour when factoring in overtime) Do the math: if that one guy can put together 50 an hour, then that's 2 cents in extra costs per tablet order. (they are actually much more efficient) The most expensive part is getting the materials -- NOT the labor. Compare that to saving money on customer service for complaints on the charger.
I honestly don't care if you have a different opinion. But, keep your snide remarks to yourself. If you don't wish to participate in a friendly debate and continue to flame then fine, you win. It's really not worth my time. Try to realize that some people might have different opinions from yours.
Clearly, almost everyone had difficulty putting the damn pieces together. Do you honestly think people share your views on that being a good thing?! I really don't know what chargers you've used but I've never had trouble with others. I have never broken an adapter before so that means, they must be well built, right?
Even you admitted that it was more difficult to assemble than other chargers. How is that a good feature when most other chargers don't require assembly at all? Again, it cost almost nothing to have it assembled in the factory to begin with AND all the tablets I've seen didn't have this adapter "feature"-- so, what is your argument again? (I guess Asus, the multi-billion dollar company, can't afford it) Hell, why did they even assemble the tablet? Save costs! Send me just the case and the insides next time too.

Exactly my point.
I really don't see how pre-ordering one with no timetable for release is an option.
And you're exactly right: the cord is much too short. I guess that's okay since it saves production costs

I never said it was good that it's harder to put together, I just said I like it. My only original point, which still stands is that it's a solid built charger which is only proven more by the fact that even though we have to press quite hard to put it together there isn't a single report of a broken charger. You can say all kinds of other non-related nonsense but the fact remains; it's well built, even if it's hard to put together.

I've never seen a adapter from a big company that wasn't "well built". And my argument still stands that they could have made it less frustrating especially given the fact these adapters are hard to come by. (I guess this is the nonsense part: me expecting a more fluid experience)
Anyway, I'm done arguing about a stupid charger.
My original intent was to help others who didn't know why their chargers weren't working. This was the case until you came out of nowhere and called my views "skewed" about a single comment I made on the quality/design of the hardware. (like if this thing was God's gift to the world and the other manufacturers were making crappy chargers; like if that was the whole premise of my post) Do you think it really matters if this charger should be classified as good or bad hardware?! (well, to me it doesn't) If you want, I will go back and edit my original post because that wasn't part of my original intent anyway.
Again if TL;DR:
a) If the device doesn't have the thunderbolt sign, then it isn't charging.
b) The adapter needs to be pieced together fully. (even if it feels like it won't go in)
c) Force is needed until you hear a click sound.
If you don't mind, I would like to continue helping those who need troubleshooting on their devices.
This adapter is a piece of crap. My adapter melted the first time I plugged it in. Well built. haha... I went to best buy and picked up a Dynex Ultimate charger for 30 bucks. It has a 10 foot cord and works great it charges at 11 volts/1.5 amps.
http://www.bestbuy.com/site/Dynex&#...d=9462949&st=dynex ultimate charger&cp=1&lp=1
ohh, here is a pic of my melted adapter
Soooo, does anybody know why in god's name the adapter was shipped in two pieces? lol
Finally I have my replacement, but they have sent me another box aswell with cellotape and stuff to return the old one back in??
Anyone else had this?
Yes, I got the same. My old tab is packed up and ready to go... I just hate letting go from my hands. I was thinking to keep it for parts, but realistically there is no need to do so and it is really just clutter.
Sent back in time via Android 9.0 TimeText feature.
Yeah, I was going to keep it as it remove the OTA kill switch folder and has been fine.
I got an Identical package as you it seems, assuming your in the UK since the sipping address is going to liverpool, I cant see Nvidia coming knocking at your door looking for the old one back. I mean if its possible to with out getting in any trouble I'd love to keep my old one, and just be careful with the dodgy battery. Does any one know how many of the apparent 88k tablets actually have blown up/caught fire?
yeah im in the uk, i think i'll get keep both for awhile and see how it goes lol dont know how long that tracking info will last either
Had a similar white paper sent to me with my replacement tablet as well (Norway) although I'm not sure if they had the part where it says "read included info to return tablet".
As far as I know the new tablet you got is a freebie (pretty much) and nVidia is probably just forced by legal obligations to send out these messages to certain countries in order to avoid themselves being liable for any further use of a faulty device.
Also I've had no problem running my old tablet with a faulty battery, it runs just as warm as my new replacement one - although bear in mind I use neither for heavy computing/graphics so they don't experience much load.
I have struggled to compare images etc. online in order to answer this. I am sorry if this has been asked, but I have googled and searched within these forums before posting this.
Let's say I got an N915P (Sprint) in great condition and obscenely cheap, but with a bad ESN.
Would the space inside and the components me compatible with the logic board from the N915A (AT&T, preferred) or N915V (Verizon, workable)?
If so I can have a working Note Edge up and running for (relative) peanuts. But I don't want to spend a lot on a logic-board that will not fit, or will have different cable fittings.
It looks so far like they are all very similar. Does anyone have experience with this?
Kind regards,
John
EDIT: Currently bidding on an n915a motherboard, if it stays at a good price and I win, I can update this with my experience.
I still highly appreciate all/any response, as it might discover that I should stop bidding immediately
Important update to anyone who needs to know the outcome of this:
I was able to swap the Verizon and Sprint motherboards very easily thanks to the phone's design, and everything works completely naturally. This feels like it has always been a Verizon device.
I swapped the charger port / mic setup at the same time, in case there are any differences, as there often are.
I hope this is useful to someone.
