SONY VAIO power up failure
Posted on 2007-04-04
I am working on a SONY VAIO Model VGN-FS675P/H laptop. The client stated that the laptop which was refurbished, worked fine until a month ago when it started to fail to start up intermittently. About a week ago it wouldn't start up for him at all. The power light comes on, and the battery light if it's installed comes on, both solid.
When I first turned the laptop on, it actually powered up and booted to Windows XP. Subsequent tries to power up the laptop have failed. Here's what I've tried so far: I used a different power adapter, one I know works, with and without the battery installed. I have taken out the RAM one stick ant a time and tested each independently. I have removed the hard drive and tested it in another machine, it's fine. and I've removed the optical drive with no change in the power up results.
Should I assume it's a mobo issue and move on, or is there something else I'm forgetting to try?
