Laptop powering up intermittently
I gave my daughter a laptop about 6 months ago. It's been working fine until about 2 weeks ago. She told me last night that the power won't come on. I played with it for about 2 hours getting it to come on every once in a while. While the computer was on and in Windows I checked to see if the battery was charged, it was.
I took the laptop apart and checked all the connections. I re-applied thermal grease to the cpu. Made sure the fan was working. Made sure nothing was blocking airflow, etc... I did check the RAM in another computer (before I got it to boot), it's ok. Couldn't check the hard drive in another computer, but I know it's ok because it finally booted.
What advice would anyone give? Maybe the Battery? Maybe the Power Supply? It feels to me as if it's a power problem, but I'm not sure what to check next.
The specs on the Laptop are:
DuraBook
AMD Sempron 1.8ghz
1gb PC 333 DDR 2700
80GB Fujitsi Hard Drive
DVD/RW Dual Layer
Windows Vista Premium upgraded from WinXP Home
