Sony Vaio, 4 yrs old, 3GB RAM, Intel Dual Core 5800, 2GHZ
My screen is becoming more dim. I have the screen brightness on high, have tried high performance power setting. Majority of time laptop is operated with adapter plugged (no battery).
Any adjustments that can be made ? Feasible to repair or best to replace ?
(No problems in past, system meets my needs)
Advice appreciated !
