I can't assess it on my lap top. Why doesn't it open?

Open it and remove the coin chaped batter to for some minutes to clear the hardware password.

If it is Windows login admin password it wants, just reinstall Windows.

It is possible that either that the movement of the watch is not aligned properly after a battery replacement.

Remove the main battery and try again, if no change! the DC jack in the laptop is a common source of trouble and must be dismantled down to the motherboard level to address, bad solder connections are common under the plug, I recommend you have it fully assessed before repair.

Depends what your TV supports. You could do vga to hdmi cable if your tv is newer, this will only do video since vga doesn't support sound. You would need a headphone jack to whatever your tv supports for sound adapter.

Try the next oldest restore point until the issue is resolved. Any software installed after the selected restore point needs to be reinstalled.
If system restore still doesn't work, run the "Pre-Boot System Assessment (PSA) Diagnostics and Error Codes For Dell Computers", you may click the link below to go directly to the support site, it contains instructions in running PSA Diagnostics and Error Code List with possible fixes.http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&l=en&s=dhs&docid=266787#Issue2

Hi there!

Is there any USB device connected to the laptop like printer, USB memory stick, scanner, etc? If there is, I suggest you remove it before starting the computer.

If there's nothing connected to the computer then it is a possible hardware problem. If you know how to open the computer, I suggest to remove the memory and place it back. if that doesn't work, it might be another hardware causing the problem. Call ACER so they can help diagnose the problem. If the computer doesn't warranty from ACER, I suggest to bring it to a qualified technician.

Hope this helps.

Acer Aspire ONE series, does not have CD/DVD drive.

You must buy external CD/DVD drive:

mcdevito75 here, You can try to presss the shift key, also try to put your lap top on, with either AC wall power or battery. If this doesn"t work bring the lap top to a local Radio Shack, or Staples for help.

the cable inside is loose

Hi there,

There may be a problem concerning drivers for WinXP.
- it seems like that Vista is the supported software, however,
try downloading this update software for your laptop, from HERE:
if this doesn’t work, I´d suggest that you go back to Vista.
