Introduction |
| This is a replacement guide for the CMOS battery for the Lenovo ThinkPad T430s. | | | | | The CMOS battery powers your laptop's BIOS firmware, which is what boots up your computer and configures data flow. You can tell if your CMOS battery has died if your laptop is slow, fails to boot up, if drivers disappear, and if your laptop's date and time are incorrect. | | | | | Before continuing with this guide, make sure you review the [link|https://www.ifixit.com/Wiki/Lenovo_ThinkPad_T430s_Troubleshooting|troubleshooting guide|new_window=true] because sometimes things may become fixable without removing the CMOS battery. | | | | | Make sure to [link|https://lifehacker.com/how-to-back-up-your-computer-to-an-external-drive-5816453|back up|new_window=true] your data before replacing it so you don’t lose any data while you’re doing the replacement and if you do, you will have a copy of the data. Make sure to power off your laptop completely and disconnect from any external power source prior to beginning the process. |
