CMOS Checksum error on power on
Hi,
I got a "CMOS Checksum Error" every time I power on my pc. How can I solve this? What's going on? I have replaced the cmos battery recently. TIA |

: battery is in backwards or is defective. you did not enter cmos, make appropriate changes, and then save those changes. I have entered the CMOS, made appropriate changes and save. As for the battery, I haven't any troubles before after the change. The problem is, the error would come up again on the next power up. TIA |

I have entered the CMOS, made appropriate changes and save. As for the battery, I haven't any troubles before after the change. Is this before and after? after the change? before the change? If your saying 'no troubles' before, why did you change the battery? If this started happening after the battery change, then the battery is wrong type or defective. A checksum error occurs when the cmos chip drains the power of the battery or there is no current to support the saving of information. The most obvious sign is when your time is incorrect after each boot. The problem is, the error would come up again on the next power up. TIA |

TIA Just for the heck of it, go into the bios menus again, and exit saving changes (even if you make no changes)... just do again even if you had already. I suppose it's a silly question but when you changed the battery, are you sure it was a fresh battery installed? Some places don't rotate stock properly and so inevitably someone ends up buying old batteries. |

: After changing the battery, did you short the pins next to the battery with the computer OFF? I guess a full story is in order. Sorry if I don't explain it sooner. The problem started with the old battery. Because of it, I changed it. No, I didn't short any jumper when I changed it. After the change, the problem persists for the next 2 power up boots, then everything back to normal. No checksum errors since then. This is what I meant by "I have no problem with the new battery before." About three days ago, I have what I believe is a blackout. Luckily I used UPS, and I can turn off my PC. Then I found out that my wall mounted power outlet have melted, somehow. Even the walls surrounding the outlet is searing hot. I panicked, cut the main power for my home and replaced the electrical wirings. The new wiring scheme seemed to work fine, at least I tried a dozen other appliances and they work fine for me. Then I tested my PC last. That's when the checksum error occurs again, and still until this day. So, am I required to short the pins when I change cmos battery? Strange, AFAIK it's not required. Which pins do you refer to anyway? The Clear CMOS jumper? TIA |

TIA you are not required to clear the CMOS when you change the battery... but since you are having problems you might as well do so and see if it can solve your problem. |

TIA that would be the one sometimes when changing the battery, you attempt to put it in and it slips out and proceed to reinsert it, this process powers the MOS temporarily and can corrupt it....clearing helps to fix this. |
