To perform a power drain, please follow these steps:
I. Disconnect all external devices and cables from the unit.
II. Power off the unit.
III. Press and hold the power button for 10-15 seconds.
IV. Power the unit back on.

BIOS/CMOS Recovery:
Please turn off the computer, ensuring the AC adapter is connected to power.
I. Press and hold the Windows + B keys, then simultaneously press the power button.
II. After 2-3 seconds, continue holding the Windows + B keys while releasing the power button. You may hear a series of beeps.
III. If the BIOS Update screen doesn’t appear, try the same steps using the Windows + V keys. If it still doesn’t display, your computer might not support this feature, or there may be a hard drive issue.
