Responding to CMOS keyboard error.

November 18, 2016 at 09:49:25
Specs: Windows 7
There doesn't appear to be one answer out there on the web. I built a new computer and took a few parts from my old one. When i booted up my old one (right next to my new one with same monitor and keyboard), i got this message. Well i tried everything that people posted- from clearing the bios to changing the CMOS battery. Sure enough, i grabbed my old keyboard (USB, not PS2) that i had been using before and it posted and started up, no problem. Thought i would share that for those that haven't found any answers out there. My old computer wouldn't boot with the Logitech G110 keyboard but would using the old Dell kb212-b.

Seems to me that when seeing "keyboard error", the keyboard would be the 1st thing to check, not the 3rd or 4th.

Apparently both those are USB keyboards. The G110 has an additional USB port to plug in a mouse or flash drive. I'm wondering if perhaps you connected the keyboard to the computer through that secondary USB port. Or did you connect it through a USB/PS/2 adapter? Unless the keyboard was designed as a 'combo' an adapter usually won't work.

True- but when searching or shall I say scouring the internet there was no answer. Some said it was a bad battery or use a ps2 keyboard. Figure I would post something here to help. Both were USB keyboards but the Logitech wouldn't work with my older computer (it did last year before building my new one). Didn't seem to make sense until I used my old Dell USB keyboard. I tried all the USB ports as well- nothing would post until I switched to Dell.

No- both are USB. The Logitech prevented my computer from posting- I tried all 4 of my USB ports. As soon as I switched to my dell kb212-b; no issues. Hoping this post helps someone else out there to try something like this as I couldn't find any solutions for a cmos checksum error- keyboard.

Hi Chemmig,

I feel you have not been sufficiently precise in providing ALL details clearly. Read carefully through your first post and I think you will see what I mean.

Looking here:-

http://support.logitech.com/en_us/p...

Suggests different software is required for the Logitech, depending on the os in use..
Perhaps the sw is best removal when the Logitech kb is changed to another.

Good Luck - Keep us posted.

It is possible that the Logitech keyboard is bad and needs to be returned for replacement.
If the keyboard has a built in USB hub to allow mouse to be attached, the hub is likely bad and is the cause of the error.

You have to be a little bit crazy to keep you from going insane.

It's not. To sum up, I was using the G110 keyboard on my older computer. I swapped it out as my media server and built a new gaming computer. The G110 worked fine there as well. A year later, I built a new media server to replace my older computer as I went with the small form factor. I wanted to boot up my old computer (which was now near my gaming computer and plugged in the hdmi cable as well as G110 keyboard only to get that error. It didn't make sense as I have used the G110 keyboard for years on both computers. I finally subbed out the G110 (which still works on my main gaming computer) for the Dell kb212-b keyboard (both USB). The older computer finally boot up. Like I said earlier, everything I researched online said to reset bios or clear cmos or replace battery or even swap to a ps2 keyboard which I didn't have. Problem solved but I figure I would share for those looking for answers on the web. An earlier person said well that would be the first thing to look at which I generally agree- it didn't make sense because I've had this keyboard for years on the older computer (which now doesn't work) but I am still using it for my gaming rig.
