B570 wont boot recovery key and f11 wont work.

Hello everyone I'm new here, I've had my B570 for over a year now with no problems what so ever, until last night my computer completely  froze and I was forced to power it down using the power button. I powered it back up and an error came on. It' said it was an unexpected error I/O error and it said something about a usb not being unplugged right, but a usb was never plugged into my laptop. So I was trying different boot options but none were working , I tried pressing f8 to do a safe reboot but f8 was not working. So I tried doing a factory reset by pressing f11 and nothing happened, I even tried plugging in a usb keyboard and once again nothing happened. Than I tried using the recovery key when the computer was turned off and it started up but it just would go straight to the error message. Anyone have any advice?

Re: B570 wont boot recovery key and f11 wont work.

Hi mrhoppp,


Thank you for posting and Welcome to Lenovo Community,


I’d like to ask you to turn off the machine and then turn on and during the boot please keep pressing on F2 to enter BIOS (setup utility) and then please make sure that the Hard Disk Drive is detected and then press on F9 to get the BIOS to default settings and then press on F10 to save and Exit,


After that please try the recovery one more time by connecting the charger and the battery and then press on the OKR recovery button and then select one key recovery if the error didn’t come up again with you and then restore from initial backup.


Hope the information helps. Let us know.
