If your figurer refuses to kicking together with displays a CMOS Checksum Error, chances are high that the number is linked to the BIOS (Basic Input/Output System). Along amongst this message, you lot are offered 2 options:
- Press F1 to resume
- Press F2 to charge default values together with continue.
Every endeavor you lot brand to restart your system, fails. Pressing F1 does non resolve the number either, together with the reboot error reappears. If this number has been troubling you, read this article to let on a fix.

It is the outset programme to run when the user powers the computer. This, inwards turn, is responsible for initializing together with testing the hardware, similar CPU, memory, keyboard, mouse, etc.
The checksum error is usually displayed when the CMOS contents neglect the Checksum check. This could tumble out if the CMOS is unable to retain information due to a malfunction. There could endure other reasons equally well. For instance, it could endure due to a dead CMOS battery.
Here are a few things you lot wishing to cheque upwards on to endure able to cook the issue.
Check or alter the CMOS Battery
The outset course of didactics of activeness that should endure followed to cook this employment is pressing Del push to larn into the BIOS setup to cheque together with brand certain that the appointment together with fourth dimension are laid correctly. If it appears modified or changed, it agency that the battery is dead together with therefore causing the issue. In such a case, you lot tin supercede the CMOS battery together with cheque if the employment is solved. Once everything has been verified, brand certain you lot relieve together with cash inwards one's chips the CMOS setup.
Reset BIOS Defaults
If the number persists, together with so you lot powerfulness endure required to reset the CMOS values to the defaults together with Reset Configuration Data
Boot the figurer to the dark covert amongst the Checksum error.
Upon seeing the “Press F1 to continue, F2 to larn into SETUP” message, hitting the F2 fundamental to larn into the BIOS. (You may postulate to press other keys, for example, the fundamental Del, according to your BIOS.)

Verify that the figurer has been scanned for viruses. It is possible for a virus to campaign a BIOS update to abort or fail.
Perform Automatic Repair
If you lot tin create it, together with so you lot may kicking into Advanced Startup Options together with perform the automatic repair. The Automatic Repair characteristic tin let on together with cook the issues that foreclose the figurer from starting normally.
Hope something helps!
