Hello,

Is there any known way to check Dell BIOS dumps integrity after downloading from the chip?
I ask this to make sure that I don't get a corrupted dump.

Thank you very much!

Hi everyone,

I’m dealing with a firmware issue on a Dell XPS 9315. After PopOS build in firmware update tool found and install the BIOS v1.29.1, the laptop started showing TPM errors on boot:

• Alert! TPM could not be initialized.
• Alert! TPM device is not detected.

Since then, the TPM is completely missing in BIOS and in the OS.

Here’s what I tried so far:

• Downgrade is blocked because BIOS 1.29.1 is marked as “critical.”
• Reflashing the same version does not help.
• Left the laptop without battery for a week – no effect.
• Updated to BIOS 1.31.0 – problem

...

The customer gave me this for changing the old battery, and then I replaced the new battery. always showing this message. I changed many chargers and programmed the new BIOS as well. Does someone have any idea for this message?

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?

I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...

Hi All,

Bought a used Dell optiplex 5090 SFF that had an Admin Bios password. Basically just the unit with the motherboard and PSU. No heatsink, cpu, memory or storage. I've tried contacting Dell for a Master Bios Password code in order to unlock the bios. Even though I can prove I bought the unit from an IT reseller and that the reseller has confirmed it never came with any storage etc. Dell won't help me because I can't provide the original first purchaser details, as they say they i could have access to personal info (not sure how as the unit didn't have ANY storage, memory or...

Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same

I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.

i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights

Any recommendation on what I have to do next? Thanks in advance

Hello Everyone!
I would like to know the Jumper location for the 2 Amber 7 White Led Blink Code error. According to Dell 2,7 Led codes are for display or the Display cable failure. I didn't changed the display nor the cable. The issue happens only when restarting the machine from windows and from the BIOS. And when opening and closing the lid the display turns off and never turns back on. But the machine is working! I confirmed it by pressing the CAPS Lock key. Does anybody has this issue and fixed it by jumpering some fet near the display connector on the motherboard. If So Please Help...

Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

I am new to electronics repair, so my queries could be naive but I am ready to learn.

So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...
