Working on a friends laptop, a Sony Vaio VPC EE43FX that's just over a year old.

Problem: press the power button, orange battery light comes on and stays on as long as power is held down, power light fades out after about 3-4 seconds and nothing else happens.

Gone through all the usual steps:
- remove battery
- hold power for 30 sec
- take everything apart and put it back together
- inside was spotless, no dust or dirt buildup that could be clogging things and overheating
- ram doesn't make a diff, it's not even getting far enough to care if there is any ram.
- no visible damage (ie. no fried cpu/gpu, blown caps etc)
- hard drive is fine, and contents now copied to an external usb drive.

- problem was apparently progressive, it would turn on less reliably over the past couple months until it just stopped working entirely.

From what I've found via google, this isn't an unusual problem for vaio's... not sure what to do next though. It only cost $500 new so a $300 repair from Sony is out of the question.

One thing I haven't tried yet is popping out the CMOS battery, which is because I haven't found a good guide to getting at it yet. It's on the side of the motherboard under the keyboard, not underneath with everything else.

After that, try and borrow a multimeter and check the point where the power adapter connects to the motherboard.

Any other ideas other than toss it in the trash?
