I use this computer for around 2 years already. but, from 4 months ago, it started to show strange behavior.
For example if I restart it, I have to wait for 5 - 10 minutes after it shut down to boot again.

It's still looking good. However, it was solved using a cooler. If the cooler is plugged, it can be restarted immediately.

However, the problem getting worser now. I can't boot my computer without cooler plugged into the laptop. Anyone know how to solve this?
Thanks....

where exactly you connect the cooler? in USB connector?

Using USB. The computer can detect it though hasn't boot up the system.

seems like lack of 5v current. it can be overvoltage via USB-bus. or it can be faulty southbridge chip.

don't use equipment like lighters or fans, which connects to USB. it's dangerous.

But, I can't start the computer without it...
Any solution for this?

ah! this is the problem. i can only propose to replace southbridge chip. at least i would do this.

Hahh?
what is it btw? where to find the chip?

phelios, if you have equipment for BGA soldering, you can replace it, but i suspect, it will be much easier for you to replace the MB.
