I have a well-traveled laptop that I've been using for the past three and a half years (specifically an ASUS Eee PC 1015PX), and yesterday it started acting up. It came out of sleep mode and as I was using the touch pad to move the cursor, the screen kind of freaked out. I had light rainbow colored bars across the screen and then the screen gradually faded to a muted white, where the screen was definitely on, but nothing was visible.
I'm not sure if it helped at all, but sometimes after swiping around the cursor or mashing on the Esc key the screen would come back for a moment and I could control the mouse again, and eventually I managed to get the computer to restart and all seemed to be well again. I was able to use it for the rest of the day (waking it from sleep mode two more times) without incident.
Then this morning I brought it out of sleep mode again and the same thing happened. (I usually only do a full shutdown once a week when I need to charge. The battery life on this thing has been great.)
I'm wondering if the problem might be a hardware issue like a loose connection or a dying screen, or if this might be a sign that the laptop itself is deteriorating and I should replace it. It seems like I still have some limited ability to input things into the computer while the screen is in the middle of fading, even though I can't see what's happening.
I primarily use this machine for writing and occasionally e-mail so I don't need it to do anything fancy, but I've been fond of it for its portability, long battery life, and keyboard and I'd like to keep it running longer if I can.
