What Does Cmos Checksum Error Mean
I have some experienced on PC troubleshooting but sad to say it is my first time to encounter this problem and I have no idea how to fix it.. So please I really need your help guys.... Reports: · Posted 4 years ago Top Sarris Posts: 189 This post has been reported. Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: 1. CMOS Battery may not be functioning how to solve bios checksum error properly. The battery life may have expired. (it's probably this) 2. The user or a virus may have updated the BIOS. 3. The computer may not have been shut down properly e.g. shutting off the computer’s main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off).

Sorry for doing multiple post but I didn't meant to do that because every time I post it says "404 Not found" hmmm... so what should I do first to solve this problem ????

It is usually a cr2032 that can be purchased at a walmart......etc. In a laptop, it could be sheathed in a holder of some type and be more expensive.

Hardware Troubleshoot a BIOS or CMOS 'Checksum' Error Comments By Rick Broida, PCWorld Sep 21, 2011 9:40 AM Reader Robert has an older Emachines desktop that recently developed a problem: http://www.howtogeek.com/forum/topic/bad-bios-checksum-how-to-fix-it- "I installed a driver updater tool, and when I deleted it, it did something that changed my BIOS. The black screen appears when I boot up and reads: 'System BIOS shadowed. Check time and date settings. System CMOS checksum bad--default configuration used.'" Robert says he's tried contacting both Phoenix Technologies (makers of the BIOS) and Emachines, and neither company could http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html help. (The BIOS dates back to 2003, and the system itself is long out of warranty.) Fortunately, this sounds like a pretty easy problem to fix. I don't think the driver-update utility is to blame here, but rather a poorly timed CMOS-battery failure. See, most desktop motherboards have a small battery that supplies power to the BIOS even when the machine is turned off. This battery might last two years or it might last 10, but when it fails, you'll often see an error message like the one above. (Your system will also fail to keep proper time, as the clock is one of the elements powered by that battery.) Most CMOS batteries are standard CR2032 "button" cells, which cost no more than a few bucks at your local drugstore, but check your motherboard documentation just to be safe. Replacing one is usually a two-minute job: pop out the old one, pop in the new one, and you're done. After that, you'll probably need to venture into the BIOS to reset the clock and double-check other system settings (lik

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
