Laptop not used for some years. could enter bios OK to reset Replaced U/S CMOS battery with no problem. Restarted............ Message press F1 ibm bios setup press F11 to invoke IBM product recovery...

I received an IBM laptop with same issue a few months back. The error message due to the drained out CMOS RTC (coin-cell battery), which retains and other BIOS settings.
The system is OK and all you have to do is to get the CMOS/RTC battery replaced by the a professional.
Good Luck!

IBM Laptop A22e Display an error 0175

The CRC error (POST = power on startup test) on boot up refers to the BIOS settings. This could be cause by a near flat BIOS battery and it needs to be replaces. If it is not the battery you need go to the BIOS to correct any faulty settings.

ERROR 0271

Are you a computer whizz? (do you know a lot about computers like me?)

Could be the Cpu fan (Central Processing Unit)
That could be lethal to the laptop.
Just as well it's a IBM other wise . . .
As for the error it means the time and date are not set.
soloution: run the bios setup utillity to reset time and date.
