Hello.

Yesterday my mother encountered a problem with her laptop, which led to it not turning on and expressing the behaviour mentioned in the title (you press the power button and then it turns off after a minute)

Here is what happened:
At one point i was fixing a setting on the laptop to make the laptop properly recognize the NVMe drive i put in months ago. All worked until all of a sudden the computer blue screened. The screen said it would reboot, but it never did. So she held down the power button, powering it off. Pressing it again, the screen briefly turned...

Dell laptop (E7440, uses the notorious CD3301B power controller + MEC5075 EC + BQ24715 charger IC)
Symptoms:

• Laptop works normally on a pre-charged battery.
• Battery does not charge when adapter is connected.
• Without battery:
  • Laptop powers on from DC adapter, passes CPU/RAM init checks, then cuts DC power abruptly.(seems to shutdown one of the mosfets in the charger path). Then the loop continues indefinitely
  • Speakers “pop” when power cut occurs indicating harsh sutdown.
  • If RAM is removed, the system shows RAM missing blink error code indefinitely without cutting DC power

Hi guys,

I have a Dell Latitude 5320 that i have forgotten my BIOS admin password on, is there anyway to get a master password or would it be reading the BIOS chip manually?

Thanks in advance

Hello everybody
I have a dell latitude 5330 which does not turn on (except the power button and the keyboard backlighting for a second, no fan ..), I have the primary voltages 3.3v and 5v, the 13v from the battery, no processor voltage and no gfx voltage, and I have the 1.8v present I don't know what it is for (maybe the ram), if anyone has an idea what it could be?
nb: I flashed the bios and it's the same result
