Question about HP Pavilion tx2120US Tablet PC

1 Answer

My hp tx2120 us was upgraded to windows 7 and has been working great for several months. Now it won't boot up. The lights on the volume control light up, the fan turns on, but the screen remains black. Once in a great while it will boot up and works normally, but upon shutdown, hibernate or reset it fails to boot again.

You may have finally run into the dreaded "defective GPU" issue, that plagued HP and other manufacturers. Thousands of defective Nvidia chip sets were used in the manufacture of these laptops and if you got one of these, it would last about a year, then fail, in the just the way you describe. If you were out of warranty, HP took the low road and refused to fix them, unless you ponied up $450. Then they replaced the defective motherboards with a new one, with exactly the same component.

If you have one of these, you will better of buying a new machine. I'd avoid HP though.

My nexus 7 will not turn on and its only a week old


You may want to try and do a hard reset/reboot which will hopefully bring the Nexus 7 back to life.

  1. Press the power button and both volume keys for several seconds. The computer screen will eventually blink off. Continue to hold until you see the Android recovery logo and the large Start selection at the top of the screen.

  2. Move the volume keys up and down to see the menu selections. If you don't want to factory reset, you can try to Power down or to Restart bootloader from these selections. The power key will select the option.

Hope that helps!

My asus transformer tf300 won't turn on


It is possible you got into APX mode (for transferring files with the device not in the OS using NVFlash. Great if you bricked a device). This mode is Hold VOL UP and tap POWER. In this case, you can try to use the Reset Hole on the left side of the Asus TF300 (between the microHDMI and microSD card). Try it for 3-5 seconds. Another thing you could do is hold the power button for 30 seconds, release, hold it for 3 seconds and see if it boots.

The last thing you could do is hold VOL DOWN and POWER for about 12-15 seconds until some small text appears in the top left.

I forgot password


If you can tell me what the Os do you use, it could be must better.

On XP you can try this:
Boot computer and press Ctrl+Alt+Delete twice when you See Windows welcome screen / login screen. It'll show classic login box. Now type "Administrator" (without quotes) in username field and leave password field blank, press Enter and you should be able to login Windows.
Now you can reset your account password from "Control Panel -> User Accounts".

On Win 7 or Vista:
Ctrl+Alt+Delete won't work, you have to use some windows password reset tool. I recommend Windows Password Reset.

Finger print reader not working.....??????????????


@touchcoat

Try re-installing the following and reboot:

For Windows 7
1. Toshiba Fingerprint Utility (for Windows 7 (32/64) click here,
2. Upek Fingerprint Driver (for Windows 7 (32/64) click here,

For Windows Vista
1. Toshiba Fingerprint Utility here or here.

If above steps won't work, the issue is most likely a hardware issue. To make sure that it's not, I recommend trying to do a full system recovery (if you don't mind starting from scratch - turn the computer OFF, hold the 0 key then turn the computer ON).

If you still encounter the same issue, call Toshiba support and have the unit serviced at 1-800-457-7777 (for US) or 1-800-663-0778 (for Canada).


Good Luck.

I have a hp tx2120 laptop and the is no display on the screen when powered on.


If it sounds like the computer is booting up properly, then it could be that the backlight has gone bad. This would require service from a professional.
