Hi

Have no symptoms. But did have to let new laptop out of my possession shortly after receiving it (ssd in and out too many times and managed to strip on eof the screw heads using a screwdriver that was just slightly too large).

Anyways, I am now concerned that as this was a 'backstreet' type of service, i.e. no shopfront, no paperwork, minimal info on website) that it is possible that the bios coudl have been tampered with. It is probably unlikely but I am still being very cautious as I use the machine for financial transactions.

I have tried re-flashing the bios but it won't allow it becuase it reports the bios is up to date. Have tried cmd line forceit but that doen't work either. Dell eventually got fed up with my persistence (the first operative even had trouble understanding the terms I was using and just kept asking the same questions which demiobstrated a lack of understanding of the issue and what I had already done). Nex levekl technical support seemed at a loss to explain why the TPM they expected to see in BIOS was not present (even thought Windows reports TPM present and active). Call was eventually cut off and no-one called back.

So, asking here. I woudl like to force flash the bios again (with same version as is, as far as I am aware) installed. Machine is Dell DC16250 laptop. It has no Dell Support software on it as it is a clean install on a new SSD.

Any pointers very much appreciated. There must be a way to force flash the bios.

Hi Echo

I have definitly tried the exe which updated to latest version.

Trying to download the bios recovery image file gives me a webpage full of gobbeldygook...

How do I download and use that recovery file, the wesbite doesn't seem to say...

UPDATE: sorted by rightclicking link and and selecting 'save link as'. Presumbly that now runs from usb drive if I boot from it....?

I haven't had any experience with Dell systems but with my ASUS laptop and at least 2 of my desktops I've managed to flash an older version of BIOS replacing the new version sucessfully. If that works, boot your machine with the old BIOS and then shut it down gracefully, then try to reflash the BIOS with the newest version.

Hi Jabiru

Thank you I have flashed BIOS before on quite afew occasions. The issue here is that is will not flash again, reporting it is up to date when using the exe file on USB drive. I want to force flash. I've tried a command line approach to that but it didn't work. echo2446 is suggesting that I try the bios recovery file (.rcv file) but not sure how I use that.

A lot of devices do not allow you to flash to an older version.

In the end, it is easier to just use tool like rufus to bypass the TPM requirement,
