🔧 LEGAL Methods (For Owners)

✅ Method 1: Reset BIOS via Jumper (CMOS Reset)

1. Turn off and unplug the system.


2. Open the case.


3. Find the CMOS/BIOS reset jumper (usually labeled CLRTC, CLR_CMOS, or JCMOS1).


4. On the M920q, it's often a 2-pin or 3-pin jumper near the CMOS battery.


5. Move the jumper from pins 1-2 to 2-3 (or follow the label).


6. Wait 15–30 seconds.


7. Move it back to 1-2.


8. Plug in and boot — BIOS password should be cleared.



📌 Check Lenovo Maintenance Manual for exact jumper location. [Search “Lenovo M920q Hardware Maintenance Manual PDF” on Google]
