*Description*
Is your Lenovo ThinkCentre M93p Tiny resetting the date and time, losing BIOS settings, failing to boot, or powering on with the fan spinning but no display? A failed CMOS battery or corrupted BIOS configuration may be responsible.
In this step-by-step repair guide, I’ll show you how to access and replace the CMOS battery, restore the BIOS date, time, and boot settings, and use the motherboard Clear CMOS Recovery jumper.
You’ll also learn:
• How to remove BIOS passwords
• How the CMOS battery stores BIOS configuration
• Jumper positions for Standard and Maintenance modes
• How to perform a proper CMOS and BIOS reset
• Which forgotten BIOS passwords may be cleared
• Why a hard drive password cannot be removed this way
• When a CMOS reset may fix no boot or no display
• How the jumper is used for Boot-Block Recovery
Boot-Block Recovery is a separate procedure that requires the correct BIOS recovery media. Moving the jumper alone will not repair corrupted BIOS firmware.
