I'm trying to revive my Portable M5120. The screen has developed a sort of wavy horizontal flicker, faint but noticeable.
Sometimes, I need to push both buttons on the side before it will start up. And sometimes, I have to push them again before it will wake from sleep.
I get no error messages, and so far it has always started, one way or another.
It has the original Conner HD, and I rebuilt the battery with a 6V 5A TR5-6A Tempest AGM from batteryspec.com (about $20 shipped--fits easily and connects simply).
Any suggestions as to the cause and solution to these issues?
My guesses--something in the video circuit and hard drive format or end-of-useful-life...
