HP Pavilion N5190 suddenly stops functioning
Posted on 2005-05-12
I have an HP Pavilion N5190. It has Windows XP SP2. The problem with my notebook is that it suddenly stops functioning during boot or a little while after booting. At times it does not proceed beyond the hardware detection screen. My notebook started detoriating with the following problems occuring in the given order.
1. It would not boot with AC power on. It booted only on battery power. If I put it on power after booting, it worked fine.
2. After going into power saving mode (screen turns off), if left for a long time, goes into a hang and needs to be hard-rebooted to revive it. (HDD and system standby are set to 'never')
3. Now, the notebook does not boot on AC power. Even when booted on battery, it suddenly stops functioning either during boot or after it opens the desktop. The duration for which the system remains functional is random. At times it lasts only till the bios info and hardware detection screen.
It may be noted that the power on button remains illuminated but the screen is blank, the hard disk icon stops flickering, the keyboard does not function (checked by pressing num lock key). Eventually, after 5-10 mins the power button too goes off.
I would appreciate any help with this problem.
