CMOS setup and check all values, this includes verifying the time and date are correct. Once everything has been verified and changed make http://www.computerhope.com/issues/ch000237.htm sure you save settings and then exit CMOS setup. If everything appears to be correct, you can try resetting the CMOS to the default values. After the CMOS values are reset, https://blog.udemy.com/bios-checksum-error/ save changes and exit the BIOS to reboot the system. Tip: If this issue continues to occur after you turn off your computer off the CMOS battery may be failing or already checksum error bad. Before considering replacing the CMOS battery try leaving your computer on for several days. Sometimes leaving the computer can re-charge the battery. How to replace the CMOS battery. Computer improperly turned off If the computer lost power while it was still running it may have corrupted the CMOS. Make sure the computer is ready to be shut off before turning off the cmos checksum error computer. If you have a laptop computer make sure the battery is charged before disconnecting the power connection. If the CMOS values have become corrupted enter the correct values in CMOS setup and then save and exit CMOS setup to resolve your issues. BIOS update recently performed If a BIOS update has been run on the computer the values stored in CMOS may have been reset. Enter CMOS setup re-enter all values and then save and exit CMOS setup. If you are unable to enter the CMOS setup, or the computer no longer keeps its BIOS values, the BIOS update may be corrupt. In this case, we recommend updating the BIOS again or reverting to an earlier version.

2014 by Alex Barbos A BIOS checksum error is one of the most common errors you can encounter when you build your own computer, perform a hardware upgrade or attempt to bring back to life a computer that hasn’t been used for a long time. If it sounds like a scenario that’s not very likely to happen to you, think again, as computers became so un-complicated that you don’t need to be working at NASA to know how to upgrade or even build one yourself; in fact, learning how to build your own computer is as simple as taking this online course, so the possibility of coming across a BIOS checksum error one day is higher than you think. The error indicates that the BIOS is incorrectly configured or corrupted, preventing the computer from booting normally; unlike operating system errors or software errors that occur after your computer is up and running, a BIOS checksum error will render it inoperable right after you power it on, so it’s no wonder this type of error can seem like something really serious. Fortunately, it is not as scary as it seems, and fixing it is quite easy. BIOS Basics In order to understand what triggers the BIOS checksum error, what the error means and how you can fix it, it is necessary to understand what the BIOS is and how it works. Simply put, the Basic Input/Output System, or BIOS, is a program that checks if all the components necessary for the computer to run are present; if everything is ok, the BIOS gives the processor the necessary instructions on how to proceed and load the operating system. Before the boot code in the BIOS is executed, though, the BIOS data is checked for authenticity by comparing one of its values, known as a checksum, against a value stored in a memory chip called CMOS; if the values match, it means that everything is working correctly, so the boot code is executed and the computer starts normally. However, if the checksums do not match, it means that something interfered with the BIOS, so the computer displays a BIOS checksum
