CMOS Battery
CMOS Battery
Hello
The CMOS battery keeps its charge while the system is off by maintaining a small voltage level. To keep it in good condition, regular checks are recommended. If problems arise but go unnoticed, take appropriate action to address the issue. Thank You
It should not be unremoveable. If there is no battery then one assumes it's stored in NVRAM. Most motherboards still use a coin type battery that you can find on the board. I recently bought a new case and as I was moving the PC into it I went ahead and replaced the battery while I was doing it. It does require you to reset everything in the BIOS though, so take some notes before doing it if you have custom settings there. A battery should last 5 or so years.
You can indeed change the battery, but if it's removed, what precautions should be taken? Which settings will be altered?
All your BIOS configurations will reset to the original factory settings. Any adjustments you made, such as setting memory to XMP, will return to the standard, slower defaults. Likewise, any overclocking changes will also revert to factory defaults.
If you haven’t altered the BIOS settings, you should be okay. Taking notes before replacing the battery would be beneficial. When I first set up the PC, I made several changes. I strongly recommend turning off unused components like the built-in audio and CPU video, as these are not essential. There might be options to save configurations to a file on certain systems, allowing you to restore them later after replacing the battery. However, since each brand and model behaves differently, I’m unable to provide specific guidance on how or where to access this feature.
I will include a suggestion.
When answering your question, keep in mind that regardless of what you're doing or planning, always make sure all crucial information is saved at least twice in separate places away from the laptop. Check that the backed-up data can be recovered and read properly.
