Re: Lenovo M92p TINY 3238 lost ability to boot after BIOS update

sorry I did not update this thread but the issue is already resolved in another forum I asked for help, it was indeed the 8MB ME bios that was very corrupted

The 2mb and 1mb I posted are perfectly fine btw

System is already up and running again!

Hello!
yesterday I received from eBay a Lenovo M92p TINY model 3238 system with 4GB of RAM and a 500GB mechanical HDD.
I tested it and it worked fine, it booted to a fresh Win10 x64 French OS .
The plan was to replace the mechanical HDD with an SDD one and upgrade RAM to the max 16GB since I had 2x 8GB SODIMM modules.

I noticed that there was an update on the [url=https://pcsupport.lenovo.com/gr/en/products/desktops-and-all-in-ones/thinkcentre-m-series-desktops/thinkcentre-m92p/3238/3238br3/pb1427n/downloads/driver-list/]Lenovo support site[/url] so I thought...

Re: Help replacing 4 diodes with rectifier and improving old AT PSU

allrighty then! I'll do just that with a small change: nippon chemi-con caps instead of panasonic ones: I can't get another quality brand here other than chemicon (tbh I can't complain because the other alternative is LeLon caps....)

thanks again for all the help!

Re: Help replacing 4 diodes with rectifier and improving old AT PSU

Thank you all so much for the suggestions/help, seems like the diodes will remain in place.
There isn't any problem with them , I just thought a bridge rectifier would be better to have.

What about input filtering? Do you think I should bother installing missing components?

Hello!

I am trying to recap and improve an old AT PSU that I plan to use with a 386DX pc

Here is a photo of the pcb:

Input caps are Panasonic 330uf/200v so I left them in alone , all other caps were PCE-TUR and missing from the photo for obvious reasons

I will replace the missing caps with Chemi-con ones and I am thinking about replacing the 4 diodes with a rectifier and maybe adding some of the missing input...
