BIOS Dell Latitude 5580 cdm80 LA-E092P Rev1.0(A00) 2017-04-22
Hello sir
Can you help solve the problems?
There is no tpm and ptt
When I restart it, it does not boot again, just a black screen with no data
I press and hold the power button until it turns off and then restart it to make it work again
Thanks​...
