Hey folks, I have a SONY VAIO VPCEB390X/PCG-71211L laptop that won't boot up correctly. It either goes through one of two scenarios.
FIRST SCENARIO:
When I press the power button, this is what happens:
1. the power LED will come on for a few seconds
2. the fan will spin up
3. It turns off after another couple seconds of it being on, with a beep as it turns off.
SECOND SCENARIO:
1. The power LED comes on for several seconds
2. It blinks on and off periodically at set intervals
3. Fan does not power on at all
Plugging in the AC adapter does not result in the charging indicator LED to light up. for both cases.
I took it apart and removed the cover, put it back together and it started working again yesterday, but it stopped working again today. I'm kinda out of ideas, what should I do?
POSSIBLE REASONS (from other posts):
DC power jack needs replacing (really hope it can be just this)
Power Adapter replacement
GPU needs heat reflow
Motherboard needs replacing
RAM module/slots malfunctioning
Overheating
NOTES/THOUGHTS:
CPU Thermal Grease is hard as rock, removing heatsink brings CPU along with it.
Thanks in advance!
