How to change the cmos battery on a touchsmart 310 1020

  • Study the Upgrade guide from HP before starting so you can remove the battery if you drop it in the machine by accident. As of the time of writing, there is no dedicated guide on how to change this battery the long way. Because of this I am going to recommend reading the HP upgrade manual for now. Once you have the back removed, remove the screws from the motherboard EMI shield. These are all the same length, and can be sorted in one pile. Find the battery and remove it from the system once you find it.
  • You should ideally use ESD safe tweezers for this procedure. You are after all, poking around at the system's internals semi blindly. It doesn't hurt to be sure.

    There's only two ways to reset the CMOS battery on this laptop.One is to short out two solder points on the motherboard, which works on this model, as per this guide:

    The other is to contact Toshiba for support. They'll be able to help so long as you can prove ownership.

    I replaced the cmos battery and cleared it

    You cleared your cmos while windows was installed. NEVER reset, clear or load default w/o backing up your system before. You changed something in the bios that is no more according with the windows configuration. Good to find what. Try to reconfigure your bios maybe it will solve your problem. But if not you've to reinstall windows.

    If your cmos battery is new and the date and time not change. Try the following.
    1. Clean the cmos battery terminals.
    2. Check your mother board if there is bulges capacitor.
    3. Check the memory you have using if in the same voltage requirements.
    Hope this will help to you.

    No Nvram Found

    NVRAM should be your BIOS, if that's not found you've got something wrong with your motherboard. I don't think it's a dead CMOS battery but you could try changing it, dead CMOS batteries usually say bad checksum.

    edit: try removing any hardware you don't need for the computer to boot then if it works, add them back one by one __________________

    Press f2 to enter the BIOS while you see the Dell start up screen. Once in there you shoudl see an option to load BIOS defaults. Load defaults. This should take care of the issue.

    If you've replaced the CMOS battery, set the date and time as well.

    If the CMOS setting default to the very first date (1st January 20??), it'll automatically report the "Check CMOS" error.

    Let us know if this works,
