La batterie du système est faible... que faire ?

battery low... please charge !

Alert System battery voltage is low.
Press F1 key to continue, F2 to run the setup utility.

When I turn on my desktop computer that is 4 years old, I get this message. I have to reset the clock. My internet is very slow and I feel like my Norton antivirus is completely destabilized.

Thank you for your help.

Alert! System Battery Voltage is Low

The system battery is not providing the correct voltage.

There you go, this has nothing to do with the power supply or anything else, it's the BIOS battery that's malfunctioning.

Thank you for your response,

But the warning left as quickly as it came!

Once again, a big thank you to everyone.

Hello,
SYSTEM BATTERY LOW: A common message on laptops when the built-in battery test on the motherboard sends a clear and critical low charge signal to the BIOS and the system. You should have a visual indicator available in the Windows systray that will show you the actual remaining charge.
NOTE: Some batteries (e.g. Li-Ion) need to be fully discharged before being recharged; for stability and longevity reasons of the cells (and thus the battery).
So in short: Remove the battery and insert it into a suitable discharger/charger. If your battery no longer holds a charge, replace it (average lifespan of a good and well-maintained laptop battery is 3 to 5 years).

Hello,
With a lot of delay, I found a note in my archives regarding this type of message. It may appear if an inverter is connected and has been poorly configured from the start of the installation.

to keep an eye on then... have a spare battery ready just in case.

Your power supply must be a bit weak compared to all the components of your PC.
