(IMBX20i does not power down on time (common problem) The common problem that IMB is connected to X200X201X201I or above is that 1 is that the BIOS is bad; If there are traces, use BAG to bake the board first. Fault scenario: plug in the power supply or put on the battery, sometimes it can be triggered, and even can be turned on. Press the power button immediately after inserting the power supply, sometimes it can run to 4A, sometimes it is E3, and sometimes it will power off after running the full code. There is a special phenomenon that is to take the swap adapter out of the machine for a long time (more than a minute), and then insert it, there is about a 60 hance that the machine can run the full code when it is running. If it is dialed down and then inserted, it may only go to E3, or even if the above-mentioned exchange light flashes, it will be powered down. (What problem can you think of from this scene?) It is still not possible to flash the BIOS first as a common problem. It should be that the machine has entered the maintenance state, and, according to the characteristics of IBM computers, this maintenance state is likely to be released by the TB chip.
