My UPS failed today and laptop ceased working. UPS failed me before 1 time and it was when laptop was on standby but nothing happened to the laptop however. Also there were times when laptop was working and UPS failed as well but laptop did not malfunction. This time i have got what i deserved. I should have been seriously suspicious when UPS failed me 1st time but i did not take it seriously.
When i turn on laptop, power button light and power led are blinking, i hear laptop working and DVD drive also is activated as usual but screen does not show anything.
I have filmed it and here is the video:

Mouse, USB Hub, power supply and LAN cable were connected to laptop at the time of failure. Do you think it was power breakout that went through power cable or LAN cable? I did not smell smoke or anything.
What can be the problem? I already paid $150 to replace cooler i spoiled. I also paid $50 for 2GB of RAM and this laptop means more to me than any other. I could send it to HP lab, but labor and parts will cost a lot.
Don't know what to do, continue with this laptop which i bought in 2006 or buy new HP laptop which is a lot stronger and costs twice as much to labor and part replacement.
UPDATE! I have solved the problem by reinserting RTC battery. In the process i have got the following screen:
What means "System CMOS Checksum Bad"? I have saved changes and laptop is in working condition, that is hardware speaking.

Have you tried booting with the battery removed. I have seen this on a Dell with a bad batttery.
Many UPS systems will not pass power when there is a failure so it may be something else.
As to repair or repalce... It is usually very expensive to repair a laptop, especially a mainboard. If a power surge was the issue, fixing one piece amy only get you working til the next component fails
