Error when booting up the switch 2101-0001

Hey just wanted to see if anyone knew what to look for with this issue. I have seen it from DRAM to the M92T36. The switch wouldn’t turn on even on the charger, I put it a spare battery and when loading up I received the error. Instantly and couldn’t get passed it. Any insight would be great!

I fixed this with some combination of replacing the M92 and reflowing the DRAM.

I had it multiple times, always had to do with badly solder joints on/ or faulty m92 chip. Always solved it by reworking or replacing the chip.
