Restore your Laptop to Factory Settings is an EASY utility BUILT into Windows -- it CLEANS EVERYTHING...computer and hardware. But, it is HANDY. jQuery(document).ready(function(){ jQuery('.intro .thumbnail a:first').attr('href','http://i.ehow.com/images/a06/6v/d1/reboot-laptop-back-factory-settings-800X800.jpg'); }); Rebooting your laptop back to its factory settings restores your computer and its hardware to its original settings when it was purchased. This is helpful when troubleshooting major hardware and system performance issues. It can also be used to fix virus related issues. Restoring your computer to its factory settings is similar to performing a clean install of your operating system. Windows uses a utility program called System Restore that allows you to restore your computers settings to a specific date.

You are right on your first assumption...the RTC battery is dead and keeps resetting the cmos control settings. The operating system however is updated to the present and that is where things don't want to play nice together. Change the battery, boot the laptop in safe mode with networking, adjust the date and time. When the laptop loads and is stable, then try to reboot normally into windows.

Below is the link to the service manual for that laptop, you can either click on or copy and paste into the browser address bar. It is free to use, copy and print.

Your RTC battery or CMOS battery is either dead or too low to keep the correct settings, windows will not operate correctly without the proper date and time kept. This battery has to be replaced for your system to operate. Below is the service manual that will advise you of the proper procedure to replace the battery. Once the battery is replaced, reboot the laptop, go to the BIOS screen and reset the date and time, then reboot as normal. In the case of your particular laptop, the laptop has to be disassembled down to the lower case and motherboard. The included service manual has the procedure for this.

This error message is generated when the BIOS Date and Time is incorrect. Go into the BIOS configuration to change the Date and Time. When you reboot and still get the same error message then the BIOS battery is flat and needs to be replaced and the Date and Time setting needs to be change to the current Date and Time after replacing the battery.
If you cannot get into the BIOS configuration (press F1 on bootup) or you get a lock icon in the top LH corner of the screen, this is a Power on Password symbol, enter the passsword to bootup the laptop and then press F1 to get into the BIOS configuration.

Go into your BIOS and change the date there and the save changes and exit. Hopefully on the reboot when you get into windows the dtae will read prroperly If it does then turn off the laptop and then turn it back on and see if the date is still reading properly. If it does then you know it was a BIOS issue.

If the date still doesn't read properly then you know that the BIOS battery is weak and not holding memory and so the battery would need to be replaced.

do you plug into a network with a server if so set the computer to not change time to server time.

Try to start your computer in safe mode and uninstall your last installation of antivirus then try again. Make sure your computer is not set to automatically reboot after any updates or anything. These settings should be in your anti-virus software
