[Q] Powering a TF-101 with a dead battery

I did something drastic today. I ripped apart the old TF-101 keyboard (already broken prior) to get at the battery pack inside, opened my son's Transformer, and swapped out the dead battery inside with the one from the keyboard, only to find out that... the other pack is just as dead as the one already inside the Transformer.

I get the same red battery icon when I try to turn on the Transformer I just reassembled using the other battery. Now, I could in theory remove the battery from the second Transformer I have in order to do this, but opening up one of these things and extracting the battery is a non-trivial task to say the least, and I don't relish doing it again. A new battery is rather expensive, at around $40 + delivery, and to be frank I'd rather just spend that $40 as part of the cost of a new tablet. However, it turns out that there are some files inside that thing that I want to be able to recover (mostly photos and videos), so I'd ask what options I have for attempting to power up that thing one last time to extract the data from it. One way would be to use the working Transformer's battery, but that is obviously quite out of the question. I could put the thing on a lab bench somewhere (just assume that I have the facilities to be able to do this) and feed it with 7.4 Vdc along the same 8-pin header that the battery uses, to fool the tablet into thinking it had a working battery, allowing it to boot. What do the wires do, and what voltage levels should they have in order to make the tablet think it has a good battery?

There is a USB mod on the forums here somewhere to feed 1 USB port on your machine 12v instead of 5v using a 12v molex feed from the PSU, which allows charging from a USB port, which would also allow data access from the same port
I`ll post a link if I find it
EDIT - Could be here somewhere

[Q] TS PCB firmware question

So, a friend of mine brought me 2 TF300T's, both with cracked digitizers, and 2 new digitizers he bought off of ebay. Both tabs are
5158n's, both new digis are G01's. Research on this site lead me to the firmware update of the TS PCB Ver. 4820. I've done all my android phones so I'm good so far. My problem is the tabs have no touch and I have no dock to enable debug mode. Someone mentioned a usb adapter connected to a mouse but never gave a description of it.
So can anyone give me a bypass or the part number of the necessary USB adapter? I have the data cable. Would a double female USB attached to the data cable then plugged into a mouse work? Thanks

Cool. Is it the same as this? [URL="http://www.amazon.com/ASUS-External-Adapter-Transformer-Series-Tablets/dp/B005PAINXQ/ref=sr_1_8?ie=UTF8&qid=1397700978&sr=8-8&keywords=tf300t+adapter[/URL]
Only reason I ask is that this one is Prime & I can overnight it.

Sweet. Thanks so much for the help guys. I really appreciate it.

[Q] No signal after screen replacement: Damaged motherboard?

I was doing a screen replacement on a Nexus 5 and a small part from the motherboard fell off.
3 pictures to illustrate the problem here:
http://min.us/mKOC4FQe6F0HI
Afterwards, the mobile connection was a lot worse than before. Now, 2 weeks later, the phone's connection has become unusable and it constantly shows no service. Only very rarely does it have any sort of connection (Edge/3G/H/4G).
Questions:
1)What is the part that came off? (see album above) My knowledge is a bit limited but I'm quite sure it has to do with the connection? I notice there are 3 other parts exactly like this spread over the motherboard.
2)Can I repair it? Do I glue it back on? Do I solder it on? Does it somehow click on? (I have tried if it clicks but this part is so tiny it's almost impossible to really handle
3)Based on my explanation, do you think this tiny part is the only cause? The phone still had some connection at first but it got worse. I'm also planning to order replacement antenna cables to see if that helps.
Thanks in advance!

In my case.. I had to replace the charging circuit Cuz it was 'broken' as described by the cellphone shop.. It has connections to the antenna.. Now phone is fully working.. Before that though, I tried different sim cards with different companies (bell Rogers and fido) all worked on my phone except my carrier sim card (mobilicity). After replacing the circuit I just mentioned everything works fine. Cost is 25$

Needs solder it's an rf trimmer /radio frequency. It's vital to an ariel of one type or other. If you want to risk a bodge assemble everything except the back and hold it in place with bluetack. If it works I was going to say epoxy it but don't. Get someone to solder it. It's easy to do if you have the skills.
Oh vital it's right way round and has now been turned. There should be a slot for tuning it.

[Completed] Living with cheap smartwatches. My life with a Hi Watch U8 Pro and a DZ09.

I've worn my Hi Watch off and on for over a year now.
I has served me well considering how little it cost. I've managed to use most of the features and the battery is still going.
So why did I buy a DZ09? Partly out of desperation. The Hi Watch has a deeply recessed usb charge port. The Micro USB supplied is slightly longer than any other I own. It is the only cable that will work and when it inevitably goes missing I am watch-less until it resurfaces. The DZ09 was cheap, it was shiny and there was a slim chance the charger cable would fit the Hi Watch.
Guess what... it doesn't.
But that's OK, the old cable turned up again and now I can use both and compare them to my hearts content. :laugh:
If anyone has any questions, I will try to answer them. I will also include the odd mini revue of different functions and any apps I encounter along the way.
Hopefully it will be of interest to someone, so here goes...

A note about straps.
I've never changed the straps on these watches. However, the Hi Watch (U8 Pro) will probably change fine. It has tiny hex bolts holding the strap on which are clearly visible.
The DZ09 is another story.
Upon inspection I discovered that the the strap is hollow. A wire (presumably an antenna) is tucked inside. So my plans to buy a funky two tone strap may have to go on hold.

The DZ09 has much jazzier screen layouts and a choice of backgrounds.
The metal bits on the DZ09 appear to be actual cheap metal as opposed to the painted plastic of the Hi Watch.

Do you think a usb to vga connection would work?

Let me explain, I have a cathode ray television, a cube one, and I would like to adapt it as a second monitor. So I'm thinking of buying an adapter to convert its signal, the problem? my pc doesn't have another extra connector for a new monitor. After searching, I discover that there are cables that adapt usb to vga, and I more or less trace what you can see in the image. My doubts are, would this set work? regarding the USB to VGA adapter, I have not seen many tests on the internet of this working outside laptops, but it has a usb 3.0 connection, could it work in my computer?
I don't really care about the imput lag, I just want to know if it would work or because of the power load or something like that it wouldn't work.

Nice artwork. It should work.
It depends on your system recongnizing the "USB to VGA", which is an external video card.
You could do it with a internal video card if you have the slots.

I do not understand. The usb to vga adapter I saw was a cable, and to use it you had to install their respective drivers. My pc supports video cards, but because of my budget I can't get one yet. If I had one, I would just look for an hdmi to rca adapter.
Thanks for your answer, by the way.

Well, that little thingy with a plug has a frame buffer and all the things that a video card must have.
It's just that instead of connecting over PCI it connects over USB.

Oh, I get it. Thanks for your help

I'll point out the obvious that you can pick up a used LCD monitor for $10 at any charity shop.
The image will be better and you won't need the VGA to RCA adapter.
