the questions people ask you are the most important things to address not the guesses made without knowing all the symtoms.
Do you even get a post screen or even a flicker of color shade?
Is there a power light (LED) or hard drive activity light (LED)that flickers?
Can you hear the hard drive spinning?
Does it have a video output plug like the question in post 17? diagnostics is about finding what you do know for sure then figuring out how to find what needs to be known next.
You have backup hard drives are any of them docking stations for a 2.5 inch Hard drive?That could possibly come in handy.<
Does your charging plug seem to kind of loose or wiggly?
Can you measure your battery pack voltage?
Do you have a multimeter?
Whose computer are you using now?
flickers yes, I can hear the HD spinning, i have ext HD’s handy, yes it has video output connection, NO on multimeter and measure of battery (the battery is crap).
Im using a KOREAN laptop with ME and using the English alt characters. It’s old but it’s for emergencies right now.
