I have been using my Jawbone 2 for a couple months on this phone. The problem I have is sometimes when I turn on the Jawbone it won't link up. There are 2 things I can do to get it to link up:
- restart my phone (then it always links up on the first power up)
or
- slide the drop down menu, turn the Bluetooth off and then back on. The only problem is that when I press the Bluetooth button it goes dim for about 30 seconds, doesn't turn off,press again, goes dim 30 seconds, then press again and it turns off. Then I can turn it back on and power the Bluetooth up and it links.
What is going on?

Bluetooth chip on the phone is ****ty! It takes long time initialize and shut down. I don't know if it takes as long as it is for you because I don't have a Bluetooth to pair with but the chip might just suck if it isn't a ROM issue.

As the title suggests, sometimes when my tf700 has had a long period of being idle if I go to use it and press the power button nothing will happen. I can still hear it functioning though cause I've accidentally taken screen shots when trying to reboot it when this happens, the screen is just black and I have to reset it.
Any suggestions?

Try switching WiFi sleep off and see if it helps.
Wifi sleep off?
I have that happen to me more than a few times. I just end up hitting power button and just tapping the corner. It works sometimes. but it's not always faster than just rebooting. Although, if you're going to reboot, just hold the power button till device shuts off.
What I think is happening is not that it's not waking, the display is just not turning on. I noticed this by plugging in the charger, which always turns on the display and device.
Yeah, the display isn't coming back up. I've noticed that too because I can still hear events occur (ie: unplugging the charger).
Another user on here tipped me off that it could be that it's in power save mode and the dimmer is COMPLETELY down, if you bump the brightness dimmer up just a hair, even 1 notch, it'll stop it from doing it, or at least it's stopped it so far for me since I changed it.
Why start two threads on the same issue?
I find that on my infuse 4G, sometimes after the phone goes to sleep, when I press the power button to turn the phone back on, the display would not wake up. The phone would be on, since if I press the volume rocker, I would hear the volume up and down keys. The capacitive keys would not light up as well tho, or respond.
The only thing I can do is a battery pull. I can still call the phone tho, so I know phone has not crashed.
This happens to my infuse 4G regardless or rom, be it, stock, CM, Aeon, whatever. Prolly happens about once a week.
Another screen related issue is that sometimes, it would take the screen like 5 seconds to wake up. So you press power button, nothing happens, you think you didnt press it, and press it again. Then of course the screen turns off, registers the second press, turns it right off again. Drives me insane lol.

that is what we call SOD (or sleep of death) it is most common while using the LB3 modem, try flashing KL2 from here (if your not on JellyBean that is) if you on JB then download and flash the one from here. hope this helps
You can also try deleting any script in /system/etc/init.d that runs zipalign. As a first step just rename the init.d folder to something else.
When I turn on my phone sometimes non of the physical buttons will work, including the power button, so when the screen turns off I have no way to turn it back on. All I can do is pull the battery and wait to see if the next time it starts up it'll work. Using the slide will sometimes turn off the screen but the phone will still act as if the screen is on, so I have to turn it off and back on. And, still, sometimes opening the slide will disable all the physical buttons and I have to pull the battery and hope it will work. And sometimes I don't have to open the slide at all and the buttons will still stop working after a day or a few hours.
I know there has to be a physical problem, but why would the power button work every time when it's already off, but (today) 1 of 6 times after the phone booted up?
Thanks in advance.

Check your water damage indicator. I've had similar experiences with other phones, specifically one that went for a swim in the toilet. Water damage could explain it.
My other thought was the connector used for the keyboard, but i don't think that would affect the power button or the buttons below the screen.
If you dig through some of the posts, i believe you will find a guide on tearing this phone down. It may give you a good idea of how the device is put together and where to potentially look for failure.
*ninja edit*
Found the teardown guide: http://forum.xda-developers.com/showthread.php?t=1586028
The front buttons (home, menu, back, search and trackpad) are on one ribon cable
The power, volume buttons are on a different ribbon cable
and last the camera button is on it's own cable.
I suspect you have a rom problem if you are lossing all button functionality at once. Have you tried the keyboard home, menu, back, search buttons when it locks up?
I would do a factory reset if you are on the stock rom or reflash the rom you are using.
And if changing firmware/software dosent help know all buttons come down to the main flex

I was able to buy a used phone and from its and this phone's parts made a working phone. There was a problem with the flex cable that was causing the buttons to stop working when I slid the phone open.

I appear to have trouble with my device's power button. I have a Pantech Sky Vega Racer 2 A830S which I took out of the box after a month in storage. It seemed okay the first few hours, but I started to notice that I could NOT put the phone into sleep when pressing on the power button once. It works like 1/10 presses. Sometimes, it even seems to do an extended hold even after just pressing once since the "power off, restart and sound profiles" popup appears.
Thankfully, the power button isn't doesn't seem to have a problem when the phone is off. When the phone is off, I can turn on the phone 100% of the time. Heck, when I remove the battery for a few minutes and turn on the phone again, the power button functions perfectly and I can sleep and wake with just a single press, no matter how fast I do it. Half an hour later it starts going haywire again. It appears this problem is truly isolated to when the phone is turned on. What could the problem be? It doesn't appear to be the physical power button mechanism. Could it be the battery or something power related shorting the buttons or something? The problem seems to be electrical in nature and I'm at the end of my wits here.
Any advice is appreciated. Thanks in advance.

hw button got jammed!!
try cleaning it up
be carefull!!!
Yeah I'd get some can air for computers and spray it. You may just have a piece of dirt lodged in there. In the mean time you could download an app that can put your device to sleep when you click on it I believe.

Hi,
I have a MTCD-KGL for over an year now. The only issue I have with the device is that after power up, sometimes, not always it freezes after start.
Precisely:
- This happens once every 2-3 boots
- This happens regardless if it does a real power up or wakes after a sleep
- The freeze usually happens 10-15 seconds after startup, however sometimes it might happen immediately or take up to 3-5 mins to freeze
- When I set it up to sleep instead of shut down (after car power off) and the radio app has been turned on before shutting down, after power up of the car and device it would usually start the radio app again and turn on the sound and freeze only after this. Same is true for my navi app (Here to go) i.e. it would start the navi app after boot and then freeze. Sometimes I'm able to make a click or two before it freezes
- If it makes cold start (i.e. had been shut down) then it shows the launcher UI
- When it's frozen I could reset it via the reset button, however I can't power it off via the power button
- When it's frozen, the touch screen doesn't respond at all, while hardware buttons only make beeping sound. However nothing changes, no matter what button I press. Turning the volume knob makes multiple beeps, however the volume doesn't change. Pressing back, home or anything else also makes beep but no effect
- Shifting to reverse doesn't show the revers comer either
I have updated to numerous different firmwares, both KGL and others as well numerous KGL MCUs, however with all combinations the problem persists.
The device is not rooted yet, I could do it if it would be from any help.
Any idea? I don't know what might be causing this freeze, which is keeping the last snapshot on the screen and buttons beep, radio plays, but nothing else happens. Apparently it's not software problem, because updates of the firmware and the mcu would have solved it. So it should be a hardware one. Any idea where to look at?
Thanks and regards

Its an older unit and I would tend to think that your system is running out of memory.
I tried doing a System Update on mine but the dang head unit can't find the .img file in any slot nor usb port.
