Trouble since replacing battery and doing a system restore
I was having trouble with my relatively new lenovo (one year old last August)- had to have the battery replaced - I never did have quality sound on the machine but now I have NO sound and the machine will not read DVDs because it indicates that I have no sound capability. Can you help?
Re: trouble since replacing battery and doing a system...
It sounds like you may have several drivers that have gone corrupt. You can try going into your device manager:
RIght Click on MyComputer Icon, left click properties, then click the hardware tab...then Device Manager...you can try removing the drivers for your DVD and Sound...and having windows find them.
But unles syou have a driver disk or can find the drivers this may be a waste of time. My best advice is to back up everything the best you can and completly retsore your PC from scratch...most users...including myself don't like to hear this.
In our store...this is usually the cleanest and quickest way to return your PC to full health.

Battery not charging usually means its dying! If your battery under one year old, you can get replacement from Lenovo. If its older than three year old, its time to find a new battery!
Is the battery not holding the charge at all? that means is the computer shutting off as soon as taken from power outlet or battery lasting less than expected...
Try launching the One Key Recovery program. 1. Back up all files that you wish to keep from the C: drive 2. Turn off the computer (no flashing lights). 3. Press the Lenovo Care Button (small button with upside down arrow or word NOVO written on it). 4. Select System Recovery (very much different from the above mentioned System Restore). 5. Select to restore to factory default settings / initial settings.
Have you tried replacing the batterys with new rechargables? if not open up the back and replace old batterys with new ones, just see if it works with a normal non rechargable batterys if it does buy some new rechargable, other than that your base i.e. charger may be faulty most likely it is the batterys.
Second, it might be you have a virus. If so try booting into safe mode run cntrl+alt+del and look for files in caps (especially LSASS.exe and WINLOGON.exe) if these files are corrupted then you might want to start backing up your data and reinstalling the OS. Otherwise run a virus scanner like xoftspy to check for viruses.
Lastly in XP, for system restore to work you needed to make periodical check points so it is correct if the last restore point was August 2008.
The only other thing I can think of is going into bios and seeing if the computer reboots itself. This would probably eliminate any virus and point out a harware failure.
Batteries in portable systems on average last approximately 300 to 500 recharge cycles (Roughly 12 to 18 months) and are considered a consumable item (Hence the 1 year warranty when the rest of the system can have a 3 to 5 year warranty). So your battery replacement is not entirely unusual. If a replacement battery is detected and recharges normally, then stops working after 12+ months of heavy use, the failure is normally the battery.
One thing to check is to see if the battery is under recall:
