Hello guys at Bleepingcomputer,

A friend of mine has a laptop that won't power up. It's an HP G61. The thing is, you power it up and the leds start blinking, the blinking pattern matches "a faulty processor". It never completes the POST. So we bought a processor and changed it. (I can do a little maintenance.) The thing didn't power up and he took the computer to another guy, who plugged her in and it powered up by itself. It worked for a few days and then, when the battery was completely depleted, the thing didn't start up again.

Any ideas?

Thanks in advance guys. This is a though problem.

Did you try replacing the CMOS/RTC battery?

A weak battery may result in erroneous error messages about system components, IME.

What was the pattern and specifically what LEDs were blinking?

The thing didn't power up and he took the computer to another guy, who plugged her in and it powered up by itself. It worked for a few days and then, when the battery was completely depleted, the thing didn't start up again.


Are you sure that the battery and power supply are working correctly, i.e the power supply has the correct amount of voltage output, and the battery is charging?

when I dissassembled it, I checked the battery voltage; the main battery was replaced after 1 year; then the power supply was damaged and didn't get an exact replacement.

So in the end the computer did power up properly but there was a warning after starting Windows correctly, that the charger was delivering insufficient power for this computer.

We never had the chance to check a new battery / pwr src combination because the computer malfunctioned completely. No messages can be seen in the display.

The pattern is one single sequence, two flashes (I was wrong, I checked it against a chronometer) in a 2-second interval, then a 3-second period when the lights go off and then repeats. The lights affected are caps-lock & numlock.

Checking on a light-code table, it says 2 flashes would mean the BIOS is damaged.

Thanks for your help.

maybe I can make it boot up somehow and re-flash the BIOS? Is that possible?

Hmmm by the way, the BIOS has never been flashed.

Thanks.

You may want to look into changing the CMOS battery.

You will also need to get the proper power supply for this, without it you will still be fishing in the dark.

Ok, then I'll have to suspend this post until I get those replacements. Thanks for your help. Is there any way I can reopen this post? It's gonna take me some time to get the replacements.

Thanks. The power source & battery will take about a month to arrive to the country.
