Screen light inconsistencies: flickers at startup; randomly works full
My 2009 A1185 macbook screen has been working inconsistently for the last few days. At first I left it for several minutes and it went into sleep mode: I 'woke' it, however the screen remained black. With a flashlight I could see everything was functioning. The screen light was simply failing. I turned it off, took out and replaced the battery, plugged it into power and powered it back on. The screen worked! However, it went into sleep mode later in the day and the previous actions did NOT lead to a solution this time. I left it alone until it was fully charged and the screen then worked. I turned it off and the next day the light would flicker on powering up or waking from sleep, but it will not remain on.
Help please!
Is this a good question?
