Looking for the Clean Me Bios dump for dell latitude E 7450 but not finding any working dump.
Anybody please help me?
I am a 62yr old (male) UK resident and am looking forward to an active retirement (although it may be a few years before I can afford it). I have an unfulfilled interest in electronics and have always wanted to be able to “fix things”. I am starting to investigate electronic repair as a hobby and I am making use of the internet and something called books🤪 which, for those younger members, are the analog version of google, you tube etc. I hope to learn and converse with the membership and then learn some more. I have a very basic understanding of electrical theory and will be learning mostly through watching you tube, reading and then trying things out in the real world. Hopefully I will not suffer from a premature home made defibrillator event and will try not to fry myself too badly, or burn the house down.
cheers and thanks for letting me join the membership

please help friends, I have 3 T490 units with the same case, the USB type C is completely dead, showing 20v 0 amp, loss of voltage VINT20_IN resistance to ground is fine, thank you
I think the problem is that I lost the voltage at PQ0008 pon 1 -PWRSHUTDOWN which should have been high which was picked up by R9512 VCC3SW, thank you very much for your help
Please help friends, thinkpad t480 nm-b501 is dead, help me fix it, thank you
usb meter 20v 0.00 amp, after I took the VSYS measurement the drop was only `9.2v which should have been 10.2v I measured from a normal matherboard machine, the VSYS path resistance to ground diode mode is 1900 thank you
