Hi, my keyboard layout seems to have randomly changed on my Lenovo Ideacentre K430.
If I didn't have a power-on/BIOS password set up on that machine, it wouldn't be a problem, I could easily find out what layout is being used from the log in screen and switch back to my preferred layout, or use the virtual keyboard.
Not so lucky: I can't boot, get to a login screen or terminal window and I'm running out of standard keyboard layout examples.
I tried:
If anyone has had the same issue and fixed it, I'd really appreciate if they could share their knowledge. I don't have a spare tower to install my hard drive in

Welcome to the Lenovo Community !
Sorry to hear of the password dilemma you are in. Removing the CMOS battery will usually clear the CMOS and remove all BIOS passwording on a desktop model. When the battery was removed with the machine unplugged from the wall did you press and hold the power button for 20 seconds or longer? Pressing the power button will help dissipate any remaining electrical charge on the motherboard and clear the CMOS. Otherwise some components can hold a charge for a while.

Hi Majestic. Thanks for the quick reply.
Yes, I've pressed the power button countless times, until I had cramps in my finger...
The motherboard has now spent 2 nights without the CMOS battery and the BIOS password still has not cleared.
One method to clear CMOS I read about indicates that one should power on the PC for 10 seconds with the jumper (or apparently 2 in my case) moved to pins 2 and 3. However, when moving the jumpers to those pins (whether individually or one at a time), my computer does not power on. It only does so when the jumpers are on pin 1 & 2. Is that normal behaviour or is that a sympton of a different problem, not just my keyboard layout settings having gone funky?
I also read that BIOS passwords can sometimes be stored on the hard drive. Could it be the case for the K430 series? (I don't think it is, else what would be the point of having Clear CMOS jumpers? I hope I'm right!)
Finally, do you know whether it's normal to have 2 Clear CMOS jumpers for that model, and whether they are supposed to clear the same thing (BIOS settings)?
Thanks again

I'm not an owner of your model and the documentation for the K430 model is rather lacking in detail in regards to the CMOS jumpers. I did a little search and found another discussion that refers to a second CMOS jumper so apparently there are two CMOS jumpers with the K430. Message #15 in the discussion I have linked below explains how another member was able to clear the CMOS. Hopefully that information will help resolve your issue as well.
The only BIOS related password that would be stored on the hard drive would be a hard drive password if that option is available for the K430 and one was set.
