Clevo Laptop Bios Update _verified_ May 2026

The Complete Guide to Updating the BIOS on Your Clevo Laptop

Clevo might not be a household name like Dell or HP, but within the enthusiast and prosumer communities, it’s a legend. As an original design manufacturer (ODM), Clevo builds the barebone laptops that are rebranded and sold by companies like Sager, XMG (Schenker), Eurocom, Origin PC, Falcon Northwest, and HIDevolution.

• Exact Clevo model number (e.g., P650RS, P870DM, NH70, L140CU). Find it on the underside sticker or in BIOS > Main.
• Current BIOS version – visible in BIOS setup or via msinfo32 (System Information).
• Reseller’s support page – download BIOS only from your laptop’s brand support site (e.g., Sager, XMG, Prostar). Clevo does not publicly host end-user BIOS files.
• AC adapter connected – never run on battery during update.
• Stable power – avoid any risk of shutdown.
• No overclocking or undervolt – reset BIOS to defaults before updating.

Troubleshooting Common Clevo BIOS Issues

• “BIOS file does not match system”: You have the wrong model or revision. Double-check your model number – a P650HS-G is different from a P650HS.
• Laptop powers on but black screen after flash: This is often an EC (Embedded Controller) mismatch. Some Clevo updates require flashing EC before BIOS. Check the readme.txt order.
• Fan runs at 100% after update: The EC needs to be reset. Unplug AC, remove the main battery (and CMOS battery if possible), hold the power button for 30 seconds, then reassemble.
• Bricked BIOS (no POST): Does your Clevo have a dual BIOS switch? Many high-end models (like the P775 or X170) have a physical switch to boot from a backup BIOS. If not, you will need an SPI programmer (hardware recovery).
