I have had to replace mine a few times.

Be sure that you have the correct sound card driver, if it uses an AC97 driver there are several different versions, also check that the sound did not automatically mute itself. Check the bios that the sound card is enabled.
Quite often the "recovery disk" that comes with the pc will reload windows and with generic sound and video drivers, they have to be replaced with the exact driver for the hardware the pc has - the best bet is to remove the old drivers first then go to IBM and look up the exact model number and see which drivers are recommended or available, usually also the IBM site will list the possible drivers for sound and they are usually available from the manufacturer site. Here's the link for IBM http://www-307.ibm.com/pc/support/site.wss/MIGR-46024.html

Right-click the time in the lower right, select: adjust date and time, select: internet time, select either source, select: apply (if high lighted)--otherwise close. You need to be connected to the internet for the internet time to work.

Did you get a complete set of IBM "System Recovery" CDs/DVDs?
If so, then reinstall Microsoft Windows, which will install all the IBM-provided software to support the DVD drive.

If you did not get those CDs/DVDs, you will need to contact IBM/Lenovo, and for about $60 (shipping included), obtain a replacement set.

download the driver of touchpad so u can use it properly

Hi there...

First of all has the touch pad ever worked?

Lets give this a try, go to the START button and left click, look for the CONTROL PANEL and double click on it.

When the Control Panel opens look for the MOUSE and double click to open page, on the tabs look for ULTRANAV, you should see a check mark box, ensure that there is a check mark under the Enable Touch Pad, hit the APPLY and OK.

Voila, your touch pad should start working.

Make sure you are using the NTFS file system and not FAT32. If so you can convert the existing file system. Also check the IBM support page for a BIOS upgrade for your model, that may help with the larger drive issues that plague alot of these machines. Just make sure to follow the directions carefully. BIOS upgrades can either got great or destroy the PC totally.

restart and try it again, or takeout battery then try to on it again

Go to Control Panel > Mouse then click on Device Settings and in the window should be the touchpad listed, under enabled does it say yes or no. If it says no then the enabled button underneath should be available.
