I have been at this problem for a couple of weeks on and off. I have searched this forum for problems relating to this issue with this laptop model and I have not found anything. I have also searched for the same issue on other laptop models in case I can glean some knowledge that will help me fix this problem. Googling has not thrown any helpful results either.
On a positive note I can see by the helpful responses that there are a lot of very knowledgeable members here, so hopefully I can get this issue fixed.
Acer Aspire 5535-723G25Mn (MS2254)
The LCD on this laptop was not coming on when the lid was opened. This was initially an intermittent problem that could be rectified by opening and closing the lid several times.
The laptop works fine with an external monitor.
I would expect his sort of a problem would normally be due to a defective lid sensor but I have not been able to locate such a sensor on this model of laptop. There does not appear to be a mechanical switch nor any kind of magnetic switch.
The screen has since taken a bit of bashing (not me – honest! It's not my laptop) and as such needed to be replaced due to a few large cracks. So, I have fitted a replacement LCD This was a converted LED from ebay (item number: 120693215178) instead of the CCFL backlight that originally came with the laptop. I have also replaced the FPC cable in case it was worn by the hinge.
I have just contacted the ebay seller in case the replacement LCD is defective.
Assuming it is not the LCD hat else could be the problem here?
Any help would be greatly appreciated.
