|If you EVER have the AC adapter plugged into the netbook or laptop when you're NOT near it or when you're not home or you're asleep, it's still possible that it's been damaged by a power spike or surge that happened during a power failure event that you are not aware of, especially if you do not have the AC adapter plugged into something that protects the computer against damage caused by those things. |
If it's been dropped the LCD display MAY have been damaged, and the wiring or the connector on either end of the wiring between the video adapter and the built in display MIGHT have been damaged or have been loosened because of that, but that's not likely. It's more likely the wiring is damaged where it passes through the hinge area.
The HP web site usually offers a free Maintenance manual for you model series somewhere in the support and downloads for your specific model
Acer does not offer free servicve manuals for you to download, but you can usually find the service manual for your laptop or netbook series when you search for one on the web, for free, or for a small fee.
I have a friend's Acer Aspire laptop that was dropped.
It has Vista on it and it's about 4 years old. At first the LCD display was not working at all after it had been dropped but the computer worked fine with an external monitor. Several months after that the keyboard and ALL the USB ports stopped working (one in the mboard, two in a card that plugs into the mboard that also connects to the DC jack for the AC adapter's connection). The computer still boots fine, the battery still charges fine, it still displays fine on an external monitor, but you can't get past the Logon screen when there's no way a keyboard will work. Previously a corded USB keyboard worked fine for that.
I found a free service manual for the series, checked the connections of everything inside the case, unplugged things and plugged them back in, but nothing I did cured the problems.
There is obvious damage to one corner of the mboard near the hinge area (the outside of the case has slight damage at the same corner) , but nothing obviously showing evidence of damage other than that.
I came to the conclusion that at least the mboard must be replaced, or maybe just the small power board that has the two USB ports on it, and doing that may not fix the problem with the LCD display. The owner chose not to risk spending any money for used or new parts to possibly fix the problems, despite my not charging him for labour.
