There are screws under the plastic around the lcd case :) Remove it with credit card and unscrew it :)

Please rate my solution :) thx for asking :)

For a factory reset there are two installation options:
C:\ drive recovery
System recovery

System recovery will rebuild the partition. C drive recovery will simply re install the C drive on the active partition. When you do full system recovery we create a hidden partition that is read only. this gives you the F10 boot-able recovery partition tools.hit f-10 on boot up

Hello

Unfortunately your computer will only support 2GB of memory.

Hope this helps..

try seating the hard drive, the HDD might have been loosened when you changed the part.

Hope it helps!

if your are talking about your internal web cam, then it seems some problum with your O.S, reinstall your windows (like Xp Professional Edition) this will solve your prob...

good luck

Run diagnostics on the harddrive. if possible reseat the Hard drive, i.e take it out and put it back again. and then try installing the OS. remember you have to boot from the laptop to install OS. Hope you are doing it correctly

You can't. You'll have to replace the lcd. You'll just keep getting more and more until your lcd dies completely.
