EXACTLY! So the difference is that the larger version is simply the STANDARD ATX connector and the other is the MINI ATX connector. I don't see that designation in the PS descriptions, just SFF (small form factor). So as I now understand it, this is a Dell-only thing. I only use refurb Dell PCs...

The only proprietary thing I see is the physical size of the connectors. I can't find a comparison or explanation of this size difference anywhere on the web. It appears to be a pin-for-pin configuration. both 24 pin, but one is 52mmm and the other is 36mm. My Amazon replacement PS just...

I have been trying to find a simple answer regarding power supply connector sizes and designations. I have a older Dell PC with a model: L235P-01 power supply. My guess is that it is bad, so I order a power supply tester off of Amazon. The test has a LARGE 24 pin socket, whereas the power supply...

Thanks for the replies. I think I have hit the wall on the BIOS update options. However, it seems UEFI may still be an option...although if it means a full OS reinstall...then probably not. This article is a good reflection of this kind of issue...

I added the Windows98_SE.img to the USB stick, booted it and it loaded. I then ran the BIOS update file for ver A15 which loaded and went through all the apparent paces. The PC then shut down, but did not power off. My guess is that it wanted to restart, but as before, it won't soft restart...

Also wanted to add that the Service Mode jumper is NOT installed. Says NC = Disabled.

Thanks for that detail buckeye... So , just to recap: I have a FAT32 formatted 4Gb USB stick with the MBR installed per the procedure. On that disk I have the custom menu.lst file and the grldr file. I also have the A20 and A15 copies of the BIOS .exe files in the root of the USB drive. Before...

Thanks for the informative reply. I'll give that a try. Also, still wondering if I should be set to UEFI or Legacy mode in BIOS and what implications a change to UEFI may involve. Not even sure what UEFI does exactly. Thanks again for your continued interest and assistance. I'd love to get...

Question: What boot mode should be used with Windows 10? My BIOS is currently set to "Legacy" mode, UEFI is OFF. Any time I leave the BIOS setting page, the PC just sits there with the power light on, and fans running. Same on restart...never restarts just sits there with fans running and power...

New drive. Old drive is on the scrap heap.

Wondering if some jumper or BIOS setting or power switch wiring could be causing the BIOS update problem. Seems to me if the BIOS or motherboard had a problem, I would be having other major issues. The BIOS battery is brand new...PSU is again stock, but problem remains. The system never...

Well, as I stated, I do have my own thread and offered my apology and link to the other thread. It's just that this thread contains useful into to both threads since I am running a third party PSU in a Dell 3020 as well. smh That said, you were right, there is no difference in operation with...

Well, fixed the hard drive crash and recovered the bad drive using minitool. That was worth the $99. New drive installed and loaded, Win 10 Pro back up & running...will test PSU theory today. Right now still running on the Thermaltake SMART 430w unit.

Yes, that is the adapter I have. So, not to hijack this topic, but as long as you have Dell expertise, why would the BIOS not update or the PC not do an automatic reboot? When I do a reboot from Windows 10, the box shuts down, but never reboots...power stays on...I have to them press the power...

Not from what I'm told, and particularly on a Dell Optiplex 3020 that supposedly "requires" their proprietary PSU. Using a third party PSU does not allow the mobo to automatically restart and it seems that also prevents the BIOS from being updated, possibly a missing status connection when using...
