Re: Dell Latitude E5450 Power Short Circuit
I've already found the problem. It was a cap near the CPU as i mentioned above. I just removed and tested it, works perfectly again.
I would like to thank you for the help and effort.
Best regards

Re: Dell Latitude E5450 Power Short Circuit
All the coils show me a resistance value above 10k ohms, except for the two coils near the CPU. I have attached a picture of the two coils. I think one of the capacitors is broken. Am I right?
The voltage on the coils and capacitors is 1.7V without RAM. (MB still on) With RAM also 1.7V till the MB shuts itself down after 3s, so 50mV nearly 0V.
And no my CPU is not soldered....Last edited by Blitzbirnle; 10-25-2021, 11:03 AM.Leave a comment:

Re: Dell Latitude E5450 Power Short Circuit
Hello Guys,
I have a following problem with my DEll Latitude E5450 with Motherboard LA9412F Rev1.0:
The problem is that the notebook goes on for about 3 seconds and then switches off immediately. The LED turns on and the fan spins. If I remove the RAM, the notebook stays on...
I've already flashed the BIOS and changed the RAM several times. And I've already changed the CPU too.
Does anybody has an advise?Leave a comment:

Re: Medion md99530 bios
Hello,
i need help! I got the ch341A Programmer with ASProgrammer Software and I have a Medion Akoya E6416 99560 with a trash BIOS.
MB Info:
D15D MAIN BOARD rev 2.1
BIOS 1 MX25L1673E
BIOS 2 MX25L3273E
I found two BIOS chips (EC and Main). I would like to flash them, but the program does not allow me to do so or does not recognize either of them.
I put the clip in the right position (Red wire - 1) and tried to detect the chip, but it says "IC not responding". I checked...Leave a comment:
