Some time ago ceased to be (in Windows Explorer) CD/DVD drive in laptop Acer Aspire 5520. Of course, any drives not readable.
Could this be the result of some of the problems with lasers or some other optical elements? Or if this were so, the drive still would be defined as mouth-in? Do I understand correctly that cleaning these optical elements/sensors will not help?
Tried to remove the drive to verify the contacts and the possibility of self-replacement on the other drive, but, to my shame, did not work. That is, if the back open the lid complex forty, it is possible to access the memory modules, fan, HDD, MB. even the processor, but DVD ROM is not directly accessible (if I overlooked).
No one accidentally has experience of disassembling your Acer Aspire 5520?
And whether any programmatic way to detect/diagnose the error? May be some resource contention, etc.? OS — Windows Vista.
