I left my hp on the bed , running, and it is not responding ........what could be the damage

the dv and tx series are very poorly designed, they can't keep the internal electronics cool enough to run properly (even under ideal conditions they will fail in just over the warranty period) with the vents obstructed cooking your motherboard becomes a near certainty.

if you really need to get this machine to boot up again (eg to rescue files before it is completely done)
step 1 power down completely (you can hold the power to off for a few sec or unplug and pop the battery.)
once system has cooled test to see if it can boot. If the lights and fans all come on but the screen stays black... (warning u should never try this with a healthy pc) ..
turn on pc (lights come on but nobodies home, no boot, no post, no nothing) put the pc into a bag or case (whatever you would carry it around in should work)
let it run for about 30 min or so (it should be really hot now)

try booting again.

it might just be superstitious but i have found that holding down the f10 key while booting seems to help. good luck
and don't buy HP unless you want a half-*** product

Try the battery removal/re-install approach. remove battery, hold power sw down for 40 seconds with power cord connected; replace battery. Works for me.

Display and Boot problem with HP Pavilion DV2125NR

It is normal for the bottom to get hot. The fan should keep it cool enough to run, but it sounds like perhaps your fan is not working very well anymore and should be replaced.

Does the computer act up at all when cool? If not, the first thing I would try is replacing the fan and examining the fan and heatsink assembly for proper installation, perhaps replace the heatsink compound with some Arctic Silver while you have it open.

HP dv9005us will not start. The computer was running , then lost the cursor. Had to control-alt-delete to resart. now will not restart. The working lights come on; click a few times; then operating lights...

okay in this case you have to take the battery out and power cord also not connected to the laptop . and then hold down the power button for 2 minutes and then put the battery in the machine and then try to boot the machine .

so that will work . if that still didnt work then boot the machine in the safe mode and then do the system restore to the erlier date .
