I do not have sound in my laptop.

When you install Windows you are given a a set period of time to Activate your Windows operating system. Failure to do so after the expiry date Windows will stop operating.
You will need to reinstall Windows so you can then Activate Windows before the expiry period.

this is the link for all drivers on this model for the windows xp operation system ...At the time this product was released ..this was the operation system used and this its probably what will support without any upgrade on memory and such ..
If you run windows 7 on it ..use this drivers ..but look for the install icon ..and click right on it .and select properties ...select the compatibility ..and tick the case for to run in compatibility with windows xp ..When yo run it ..if it makes issues click to run it with the proper changes ..9it may give you this option cause it tries to run it normal the first time and teh platform will nto allow it ..but you will have the choice to run it anyway ..and force install it cause it will work ..

I had good luck getting drivers from the Fujitsu company web page when I need them for my stylistic st1410. Another option if you are running a legit copy of windows xp or 7 the driver update feature on MS update has gotten pretty good.

these kind of problem can be solved by reloadubf your operating system .

remember during the process you will be formating your laptop but dont be scared that is the only solution to your system problem

You need to upgrade your driver for windows 7.
you can download it from
http://ts.fujitsu.com/support/downloads.html

for more information keep on posting.

if it helps you,pls rate it ..thank you ; )

If you have deleted that recovery partition then you need a Windows XP installation CD.
If you do not have this CD then contact Fujitsu for a copy of Windows XP installation CD, you may need to provide proof of ownership etc.
The Windows XP installation code should be on a Windows label on the bottom of your laptop, this is required when you start installing Windows.
You will also need to download the Notebook's device drivers from the Fujitsu WEB site to install on the notebook. You most likely need to download them from a different computer and then copy and install them onto the notebook.

I would try windows 7 as it is the current operating system that seems to work very well for me.

Windows XP SP2 isn't supported by Microsoft, anymore.

The Fujitsu site should help, they have a page with the available drivers listed. I've included a link to this page below. Hope it helps!
