Bootloader not strating

I am not able to start bootloader SencesCap. Not able toe switch into bootloader mode!

Which model of SencesCap do you have?

SenseCAP K1100 - The Sensor Prototype Kit with LoRa® and AI
The display is not functioning ether

First, run the Check Disk utility to scan the integrity of your file system and hard disk. It’s always possible that your bootloader error stemmed from physical problems with your hard disk. Second, use the System File Checker utility to scan for and fix any corrupted system files.
