It’s a good idea to change your CMOS battery. When you notice that your computer’s date and time are off, it’s likely that a CMOS battery is nearing the end of its life. Even if you set the correct date and time in the BIOS, it will revert to the default date and time. When the battery dies, the computer is unable to save the correct date and time, and this information is reset every time the computer shuts down. One of the tasks of the CMOS, as I indicated before, is to keep track of date and time. Incorrect date and time, with Constant Date and Time ResettingĪn erroneous date and time setting is one of the most typical symptoms that your CMOS battery is about to die. This could cause strange difficulties or hardware failures to appear out of nowhere. When the CMOS fails, the computer loses the ability to detect some of its hardware due to malfunctioning drivers. The CMOS of a computer is in charge of saving the computer’s BIOS settings and keeping track of the unit’s hardware drivers.

Unusual Hardware Issues and Non-Working DriversĪnother clue that your computer’s CMOS battery is about to fail is the presence of malfunctioning drivers and other strange hardware issues. Because the CMOS isn’t operating, the computer won’t be able to verify the values, resulting in errors when the device is booted. This makes it harder for the computer to validate the information in the CMOS storage, such as date, time, and hardware settings. Corrupted or erroneous CMOS values are the most prevalent cause of these issues. CMOS Reading Error or Checksum Error While BootingĪnother clue that your computer’s battery is deteriorating is if you get a read error on the CMOS or a Checksum error while booting it up.

#SYSTEM CMOS CHECKSUM BAD DRIVER#

The computer will have trouble starting up if a hardware driver involved in the booting process fails.

This is because a hardware driver could fail to function while the computer is running, leading the machine to crash.Ī dead CMOS battery might also cause booting issues, preventing the computer from beginning since some of its drivers aren’t functioning. It could be a problem with a CMOS battery. If your computer goes down for no apparent reason and then refuses to start or has trouble booting up. Computer Shutdowns and Booting Failures on Periodic Basis We’ve put together a list of these signs so you can learn more about them. Knowing and comprehending these warning signs will enable you to replace them before problems arise. When this battery runs out, the computer will experience performance issues because it won’t be able to detect its device drivers.įortunately, there are symptoms that a CMOS battery is failing. What is a typical symptom of cmos battery failuresĬMOS Battery Failures: The Most Common SymptomsĬMOS battery failures are a problem that can cause a slew of computer issues. What is a typical symptom of a CMOS battery failure? Every time you turn on your computer, the system date and time is incorrect (Time and settings lost).
