Cmos battery replacement Toshiba S1900-303

It's difficult to say but you will need to remove the underside screws and also maybe even the keyboard as it's often attached to the base. The cmos battery could also be behind the screen. Comment by sandrew, posted on Nov 12, 2006 I'm sorry but I dont have any personal experiences with your particular laptop, but the lcd's are generally held in with 1 screw in each corner normally covered by a rubber bung hiding the screws, I would be very carefull not to disconnect any wires behind the screen, if yor not sure take it to a qualified repairer. You will probably have to remove the top panel just below the hinges as they may be held in underneath

First you need to take the cover off your laptop and locate the cmos battery which looks like an oversize battery watch. With everything unplugged it just pulls out, note which side of the battery goes however. Place the new one in put everything back together and power the computer up. When it powers up it will finally get to the screen that says press "F1" for setup or "F2" to continue. Press F1 and you will get to your set up screen. You can go through each screen and select F5 which is the default factory settings or scoll across the top to the last screen which will give you the option of resetting all the settings to factory default with just pressing one of the F keys once only. Once you do that, just shutdown your computer and restart and it will start as normal. It may go through the F1 and F2 screen one more time but just press F2 and continue. After you log off the next time all your changes should be good. Let me know if I can help you in any other way.
