I've just replaced the hard drive of my laptop compac nx9010. There was an optical tap on the old drive which I took it off and stuck on the new but my touch pad mouse is not working. Can you please advice me how to fix it.

This model laptop came with a 60Gb hard disk and if you installed a much larger capacity hard disk then the BIOS cannot detect this hard disk.
For the BIOS to detect a large hard disk a BIOS upgrade is required (if there is one available) Check the HP/Compaq WEB site to see if there is a BIOS upgrade.
If not the try a 120Gb or smaller capacity hard drive.
As an alternative -
You can keep the existing hard drive in your laptop and use an external USB hard drive to store your data.

Check the HP/Compac WEB site foe a possible BIOS upgrade that can support a large hard drive. Otherwise try a hard drive 120Gb or smaller.

hope this helps

Ok it seems *********** board may be dead. However, you can take out the hard drive and place it in an external hard drive storage unit/box
and plug this into any computer, and WALAH! You have another
drive letter, which is your old hard externally. You may now get your pics. You can access them via any photo software; however, you need to make sure that you save them on another drive letter, and or folder. Not the external drive Letter it may be called D or E.

This model laptop is installed with an IDE 40Gb hard drive.
You can use a faster hard drive but the BIOS limits the maximum size hard drive you can install.
Check the specification of this laptop for the maximum size hard drive you can install.

Hi,

This could be because the key is stuck inside. Tap the J Key gently or a bit hard or try to pull it out ( dont remove it off ). Normally hitting a bit hard on the Key solves the problem.

it`s very possible to be a hard drive error, the main thing what you can do is to try to install the operating system over the old one if that goes ok it means that you had a premature shutdown and the files where corrupted if the problem persist it`s a hardware problem.. solution is to buy another harddrive

It probably is due to Spyware, Malware or other infections.
Go to malwarebytes.org and download the free scanner.
Run it and see.

That is a hard drive password. You'll have to buy a new hard drive.
