I just wanted to add that the capacitor is 10uf if you are planning to replace it. Since there are only 2 per fet, I think it is wise to replace it. However, I am definately not an expert. -
Thank you very much for that. I had a feeling it was under a shield. Mine was the one right under your capacitor. And I can feel it with my pinky finger!Leave a comment:

I realize this is an old thread. I was hoping you could remember approximately where you found your shorted capacitor on this board. I have a short to ground on the drain of fet. It is taking a maximum of 3a at 1 volt, but I cannot find anything hot. Warm, but not hot. I once found a shorted cap on an xbox board with the temperature probe on a cheap multi-meter that I could not find with my finger or alcohol. Thanks in advanceLeave a comment:

This may help others. I had a similar problem. I had replaced the fet, controller i.c., a 100 ohm resistor and the startup capacitor. The power supply would not start. Then I noticed the diode (bat54c) and 100 ohm resistor at the gate were blown. Also the 4 resistors (0.15 ohm) at the source of the fet were blown. I replaced those and everything is good.Leave a comment:

I realize that this is an old thread. I have the exact same situation as the opening post. I have the same model power supply with the 5 caps mentioned replaced. Only one cap was vented. Also, I have no shorted mosfet's. Wondering if anyone else has resolved this one.Leave a comment:

Thinkpad T460s
Type 20FA-S03E06
S/N PC0L6ZCM
Would someone please be able to look at this BIOS? The machine works fine but takes 15 seconds to POST and the MEI Version is blank in BIOS. Intel ME will not install. I had used lenovo auto-patcher to remove supervisor password. That worked and I have since updated the BIOS to the latest version. Thanks in advance....Leave a comment:

Dell E6530 Bios Request
Could someone please have a look at this bios? I have brought Dell back to life with another BIOS but would like to keep ME Region. I am still learning to use ME Analyzer. Thanks in advance.
That is actually a Dell E6530. I made a typo with the filename....Last edited by duder; 11-24-2023, 12:42 PM. Reason: That is actually a Dell E6530. I made a typo with the filename. -
Re: Msi ms-17e9 (ge75 10sgs)
Thank you, but I have already tried that. Does the EC have to be done as well, or just the bios?Leave a comment:

Msi ms-17e9 (ge75 10sgs)
Would someone have a working dump for this machine? I had a dead machine and I programmed bios with download from MSI. Now I can turn it on & off but have no POST or video. LED's come up and fan spin. I will attach my original backup. Thanks in advance.... -
Re: dell E6530 LA-7761P bios
Thank you very much. That worked perfectly. After flashing those, I was able to run the Dell Bios update from Windows and clear the missing manifest. If it helps anyone, I was able to use the clip without removing the chips from the mainboard.Leave a comment:

Re: dell E6530 LA-7761P bios

Re: E6530 LA-7761p Bios and Ec file needed
Hello - I used these 2 files for an e6530 discrete which had no display. It works fine, but I cannot update past A02. I even tried A03 from Windows as well as USB and it will not update. Anyone have any ideas? I am not looking forward to taking it all apart again. I will post my original dumps. Thanks in advance....Leave a comment:

MSI MS-17E9 (GE75 10SGS) Dead
This machine appears dead. I get 5vsus and 3vsus for about 20 seconds when I hit the power button. 1.05vsus and 1.8vsus also come up normally for about 20 seconds. RSMRST is 3v when I hit the power button. This led me to believe the problem is either BIOS or PCH? I tried another BIOS with the same results. I do have battery charge led after BIOS program. Don't remember seeing that before programming BIOS.
Any help would be greatly appreciated. Thanks in advance. -
Re: dell latitude e7470
Wow! I am amazed. It restarted a few times and then I saw the display for the first time. Then I set it to UEFI and it booted windows and then restarted and updated firmware by itself. I was beginning to think that this wasn't a BIOS issue, except I had read other posts which had the same issue. What causes this to happen? My client said he used it one day without issue and the next day it would not power up. I guess my mistake was reading the BIOS while it was in circuit, even though I had the battery disconnected. The CMOS battery was still connected though....Leave a comment:

Re: dell latitude e7470
No, I never lost the originals and I put the original back on the chip after trying the others. Here are some other backups. Backup 1 and Backup2 were taken with clip and different software. I never modified the originals either....Leave a comment:

Re: dell latitude e7470
Ok - Here is the bios removed from the board and it looks the same as the one I did on board. Not sure what I am doing wrong. I am using CH341 programmer and I tried with Asprogrammer as well as NeoProgrammer. I picked winbond 25q128fv, hit read and then save. Then zipped file....Leave a comment:

Re: dell latitude e7470
Thank you for the quick response. I was using a clip with battery and power disconnected. I will try again after removing the chip.Leave a comment:

Re: dell latitude e7470
Hello - I have Dell e7470 that turns on with no display and shuts off after 30 seconds. I have tried numerous bios in this thread with different results but no display. I wonder if some could take a look at this bios? Service tag is 2PPDVD2. Thanks in advance....Leave a comment:
