Changing the CMOS battery resolves the temporary bluescreening issue.
Changing the CMOS battery resolves the temporary bluescreening issue.
When i remove the CMOS battery from my laptop and reconnect it, the laptop stops bluescreening momentarily. Apps start to crash randomly after about 1 hour. It then starts to happen again after about 2-3 hours of use, gradually bluescreening more frequently until the laptop bluescreens on launch. I need to remove and reconnect the CMOS battery for the cycle to start over again. I also noticed at the 2-3 hour mark the time is delayed by 2 minutes althought the timezone is correct which seems strange. Do i need to replace my CMOS battery or could this be a motherboard issue?
Did you modify the RAM recently? I’d like to check if completing SFC and DISM will fix the issue, then see if a RAM test succeeds. One of them that isn’t responding right now seems to start up from a USB before the OS loads. If you boot directly into BIOS and stay there, will it eventually cause a blue screen? Also, what happens in safe mode?
Replace the CMOS battery with a fresh one; a low-voltage option might lead to instability or full failure.
Choose a Cr2032 model specifically designed for this application.
If unavailable locally, a hardware store can identify suitable coin or clock batteries of type 2032.
I suggest opening the laptop and inspecting the connector on the 2032 pigtail before purchasing. There are various termination types available (Molex / JST). The image below is just for reference; look at the lower left corner where three different connectors are visible. If you're very unlucky, the battery could be soldered in.
Additionally, some laptops require specific adjustments after replacing the battery, beyond the standard BIOS restoration steps. Search online to find out if your model will boot normally after a battery change or if it becomes unresponsive and unresponsive.
