My Shift still gets warm and the power is draining rapidly after Windows 7 is shut down. The modem is switched off already in Snapvue, and none off the led is on. This never happened before with Vista.
Any advice please??

try running cmd as Administrator and then type
powercfg -energy

My battery only last 4 hours after I power off windows 7. The machine is totally silent and all lights are off, but it still gets very warm. Is that normal?
No, that's not normal. Even though Win 7 is powered down, the Windows Mobile side stays powered, you should check what programs are running, as something must be maxing out the cpu and using your battery up.

Have you tried to soft reset WM after powering down Windows 7?
EDIT: If you're not using WM you can simply remove the battery for a couple of seconds after powering down W7. This will ensure that WM is not running at all.
There is battery leak while connected to USB with electricity power connected to computer and the pc is powered off.
I tried it on other PCs and laptops with the same result.
In an e-mail HTC informed me that the device should only be charged by connecting to power line and not a computer and I have a problem with my computers/laptop !
Any help would be greatly appreciated.
So two key events happened with my phone - the replacement battery I ordered finally arrived, and I also crawled out from under a rock and flashed the ICS partition and pengus77's CM10.
I was advised to calibrate the replacement battery by charging it from 0 to 100 with the phone powered off. So I streamed a random high res youtube video to drain the battery as fast as possible, then powered off the phone and plugged it into a USB port on my work laptop (a HP Elitebook running Windows 7 Enterprise x64).
The phone started charging (battery animation screen appeared) - and then my laptop started to install drivers. A few minutes later, I got a windows BSOD - yes the blue screen of death, not the black screen on android.
I initially thought something else caused the BSOD, so I left the phone plugged into my laptop and rebooted. As soon as my laptop got past the "starting windows" screen, it BSODed again. Didn't even get to the "Please wait..." screen.
Tried to reboot again - BSOD before getting to the "Please wait..." screen. Finally I suspected my phone was the culprit, so I unplugged it. Another reboot - it successfully got to the "Please wait..." screen, and then I plugged in the phone (still off), triggering a BSOD in under 10 seconds, before I could even get the field to input my password.
Rebooted with the phone plugged in but powered on this time, and my laptop fully booted all the way, no BSODs. But if I powered off the phone and plugged it in, BSOD! Looks like I'll have to wait till I get home to my AC charger before I can calibrate this battery
This is quite strange - I never had any problems like this on the old GB partition, if I were to plug in my phone to the laptop with the phone powered off.
Has anyone else experienced such an issue before? If it helps, my work laptop is a corporate machine so I don't have admin access over many of its functions (though I can still install and uninstall programs like normal), and it's loaded to the brim with corporate bloatware, and it's possible these properties contributed to the BSOD.
Charging(forming) new battery via usb is never recommended to be honest
Most usb device don't provide enough power or stable voltages like charger designed for our phone
I personally never liked charging via usb(most usb hub's dont work properly also if they need to provide current to hungry device(our phone example)..
I have no prob's with that options and also using custom battery 1700mah...
I have no sod's on win but have read that people had problems and sods sometimes with usb charging...
It's hard to pinpoint exactly where problem lies,could be your low power usb on motherboard crashing your win or something else..
Hmm that sounds likely. I'm back home anyways and will use my AC charger to condition the battery.
I remember that on the old CM10 nightlies (before the call bug was fixed), the USB charger always BSODed my phone...
... an easy solution would be to start using a real operating system on your computer instead of windows

Believe me, I do - I use Linux as my main OS on my home computer, and only boot into Windows for games
However this is a corporate laptop that doesn't actually belong to me and I can't meddle with it like that.
Hi,
My techlast won't turn on anymore. The power button does nothing, no matter how long I press it. Also pressing power and volume + of - doesn't do the trick.
This thursday I upgraded to Windows 10 and installed bios v2.02 plus lollipop using 'mirek190_rom_v5.0 - android Lollipop.' All went well, I could boot Windows 10 as well as Lollipop. Booted several times and switched operating systems.
Then from lollipop I chose to boot into Windows. After using Windows I shutdown Windows and it shut down normally.
Then the thing died or something, it just does not respond to anything anymore. When charging I do feel that the tablet is a bit warm, but it just does not respond to the buttons on it anymore.
Is there anything I can do besides keeping it as a coffee coaster? I have looked at how to unbrick the tablet on these forums, but I just turned it off and it was not bricked during flasing or anything. Oh, it's a c5j6
It works again!!
I connected the teclast to my laptop with USB and pressed the power button for 30 seconds (I read that somewhere). Nothing happened... Then I disconnected it from my laptop, and pressed the on button for like 7 seconds... just for the sake of it.... And...YESS, normal boot screen, chose Android and everything works! Very happy
Holy crap, I did exactly what you did with my X98 Plus — and it also worked! I've no idea why. My tablet is almost new, had it for a month or two and used it for like 15-20 hours in total, no gaming and other heavy stuff. It was ~90-95% charged yesterday, I didn't install anything new, just put it to sleep (short press of the power button) yesterday from Win10, and it won't turn on today. Tried holding the power button for different amounts of time, tried charging it with different chargers (both the charger and tablet were always cold though). Nothing. Then found your post and did the same thing, connected to a laptop, power button for 30 sec, then disconnected and power button for 5-7 sec.. And it turned on!
What's the logical explanation here, why did it turn on after that? Something to do with the laptop's usb power? Mine had a usb3 port, so it should be quite "beefy", probably the same current as some of the chargers I used before. Something different about laptop usb ports that I don't know about?
Thanks
I am experiencing some stability issues on Windows 10. Sometimes the system randomly freezes (screen stays on, but no reaction until hard power off) or does not wake up, while being charged with Windows running. Other times the system runs perfectly for hours. I am not experiencing any problems under load.
My problems are not load related, and I have disabled the fast boot option in energy management. As there is no blue screen, I cannot find any info on what is causing it. It is a clean install. Except the two drivers for the cameras, all drivers are signed and either downloaded from Windows Update or gathered by scanning the Win 10 driver folder that has been uploaded on this and the techtablet forums. The graphics driver has been updated with the most recent Intel version.
What are your experiences with Windows? Anyone experienced something similar or is there a known faulty driver?
Other things I tried:
Error check on drive
sfc /scannow
Windows and this tablet have some problems... my experience http://forum.xda-developers.com/x98...-2048x1536-t2913035/post63550338#post63550338
They also occur when idle, when using the tablet everything is fine, problems are not easily reproducable and I did not find anything valuable in the event log, so i gave up and live with it.
I reinstalled windows, tried different bios versions, drivers... energy options, nearly everything I could think of^^
Wasted a lot of time, I now hard power it off instead of letting it "sleep" or whatever it does, I guess some driver is faulty with the windows deep sleep aka "connected standby".
I narrowed it down a bit. I kept looking for driver updates via Windows Update and examining the different powercfg reports. (my thought was, if the driver or app misbehaves in connected standby, it is not good). Now the system seems stable on battery power and connected standby seems to work as expected.
I do have problems while connected to the charger. The device will not wake up after a longer time if it goes to sleep while charging. I also noticed that the sound driver seems to alter its behavior when power is connected, so testing now with volume=0. (some well known problem with the audio driver on other tablets)
My fresh install of win 10 (1511) just slept to death again. This time there was an entry in event log. LockApp.exe crashed after waking up, so silly, eventlog is full of errors that shouldn't be there on a fresh install.
One question, does shutdown work for you (win or android)? Mine seems to power off, but it isn't really off. Drains battery and before you can turn it on again you have to hard power off (even though it looks like it is off).
Positive thing about fresh install of win 10 (1511) is that wlan works out of the box, also some more drivers are downloaded automatically (but seems not the ones that cause problems^^).

I did not switch it off often enough to reach any conclusions. Seen it fail when shutting down from Windows several times, from Android things seem pretty stable. To test, I attach an USB lamp to the OTG adaptor. When the tablet shuts down it turns off USB power and the lamp turns off.
