TX 1210u Won't boot, not backlight

[hpewski]

Pavillion TX 1210us won't boot.

Plugged in, powers up.

Screen never comes on.

Hard drive led flashes.

CD makes noise.

no buttons work - mute, wireless, caps lock, etc.

nothing ever happens but the fan does come on and it appears to get somewhere...but no where.

have followed trouble shooting tips from site - RAM, tried to boot into test, etc.

Nothing.

Ideas?

Having same problem of not booting up - or screen going blank in middle of session. However all indicator lights are on. After removing battery and waiting for a while I can end up rebooting. This is an eratic problem - initially thought it was the screen but am not so sure - I am considering either a virus, software problems, or ram. Any suggestions would be helpful.

Hi All,

I had the exact same problem when turning on my tx1001au, the lights would go on fans would spin, but no screen activity.

This might sound crazy, no need to open up laptop, just follow directions below WORKED for ME. Its now been working for over a week with no problems, but i have purchased a targus laptop cooler fan to keep my lappie cool.

take out hard disk drive. So as not to damage it from the exess heat buildup.

turn on laptop,

place in laptop carry bag and zip up to get heat buildup. (i did mine on a cool night so i did this for an hour) half an hour in most cases should be sufficient

take laptop out of carry bag. turn off. press down on the enter key and the \ key which is just above the enter key, with moderate to good pressure. I used 2 fingers for the enter key to add even pressure.

(the reason for this you might ask is that the Fault is to do with the GPU which is the nVidia Graphics chip, by heating up the laptop the solder on the board gets hot. then buy pressing down on the above red labeled keys, which are directly above the GPU, you are basically reseating the GPU back into place.) This has happened on a few different brands of laptop, HP, Apple, Dell etc. so is a know problem with the same model Nvidia GPU's for all these brand laptops.)

Turn on the laptop while pressing down on the above keys. (do this as soon as possible as the computer will start to cool down and you will have to start all over again.)

wait till the fans reduce speed, then turn of the laptop again.

you might have to do this a couple of times for it to work. (i only had to do it once because i left my laptop in my carry bag for an hour to get it realy hot, remember i took out my hdd so as not to damage it)

Then with the laptop turned off again hold down the F12 key turn the laptop on again and wait till the fans spin down again. then start tapping the F12continually for about 10 seconds.

(The above F12 is like a factory reboot/reset sequence .

Then turn the laptop off again.

Turn it back on and if you pressed down just right, then you would have reseated the GPU and your lappie will be working again.

Hope this helps those people out there with TX model laptops

Hi

I just wanted to thank you for the self fix on the 'lights on but black screen at boot up'  Mine is a very similar story to many others...1 yr after purchase the problem occurs, told i need a new motherboard ($400)!!! ...

I have used your instructions 4 times since mid november (because issue keeps happening), it works each time - I really appreciate your post on how to fix a problem that should really be cause for a  massive recall! 

shame shame HP....you have lost me as a future customer and probably many others.
