If I press POWER all the lights are ON only for 2 secs and then OFF again
I don't know the cause, but suddenly my laptop died and now when I press POWER all the lights are ON only for 2 secs and then OFF again.
I opened the case and identified a burned voltage regulator near the battery charging socket. I replaced it with an equivalent spare part, but the fault is not removed. I measured all the motherboard test poits, from the adaptor socket down to the battery and it seems it is working OK, especially that when the voltage regulator was burned it was not charging the battery.
Now with the battery in its place, the battery is charging, but the laptop is not starting.

I would remove all attached items. memories, hard drive, battery.

plug in the AC and turm it on. (BIOS) only. if that is good, then install other devices.

try cold reset by removing the battery including power adapter then press power button for approx. 20 secs. then plug your power adapter then press power button again. press the numlock/ capslock button if there is response showing that your motherboard isnt dead yet. please check also when fan is running momentarily then suddenly stops then post another question here.
Could be many things. Let start with a couple of easy ones.1) Unplug charger from computer and outlet, take battery out press power for at least 30 sec. Plug every thing back power on. 2) charger bad won't turn on or charge battery, try diferent charger if don' know how to use a voltmeter. 3) power jack loose or broken. 4) last and worst mother board circuits transitors etc... btw processor, video card or input devices fried. Buy new board from ebay. Don,t fix it. Not worth it. This is Only if laptop gives completely sign of not turning at all. No lights, no hardrive or no working or fan. No signal of life. If couple of lights do turn on it can be the ram or video card, play with ram a bit. Good luck.
No guarantee but you can try this. Remove the battery and unplug the AC adapter. Hold down power button for 30 seconds. Plug in AC adapter but leave battery out. Try to restart computer. If it starts, reinstall battery. It worked on a Gateway I was working on last week. Worth a try.
Remove the battery and the power adapter, wait 5 minutes, plug in the power adapter and try turning it on, if it doesn't turn on, remove the power adapter, plug in the battery and try starting up again, if it still doesn't work plug in the power adapter, try starting up.
Is the power adapter working? does it have a green led on it that shows that its powered?
