Hello all – I have a question about a display problem on a notebook computer and I was hoping to get some input from my peers. 🙂
I have a user with a Dell Inspiron 8600 laptop which is having a display issue. The display goes from fully-lit to half-lit (e.g. about half as bright) spontaneously (e.g. random times), or more often if the laptop lid is adjusted to open it or close it a bit more. Usually you can just move the lid back and forth to get the display back to being normal, but it seems to be occurring more frequently.
I swapped out the actual display (but NOT the cable linking the display to the motherboard) but that did not solve the problem. Checked all wiring and connections and it looks good; nothing loose. It seems like something is causing the display signal to drop in strength, and I do notice a very faint buzzing sound when the display is dimmed, which goes away when the brightness level returns to normal. I know it’s not a driver or Windows issue as the issue can be reproduced during POST.
My next step will be to try swapping the cable which connects the display to the motherboard, but I was wondering if anyone had seen this issue before and might have any comments?
Thanks in advance,
