Just a little bit of info.... you're doing this ALL WRONG!!!! You need to measure the circuit WITH A CHIP INSTALLED. Your multimeter is NOT reading the correct values, because the circuit is NOT COMPLETE.. There is NO amperage behind that 5v, the IC is NOT working on 5v logic level. Those programmers DO NOT NEED ANY MODIFICATION!! The problems with the assumptions everyone is making about these devices.. 1) Making the INCORRECT assumption that the CH341A IC is always driven at 5v, but it is not. The CH341A IC can be powered by either 5v, or 3.3v (when you change the selector, that's what you're doing) This is important to know, because the IC doesn't just pass the 5v USB signals through to the SPI/I2C lines.. that would be stupid. Instead, they are converted to SPI, or i2c internally, that means the i/o of those lines are DIRECTLY proportional to the supplied power. i.e. 3.3v/5v logic levels. 2) Yes, there MAY be up to 5v present on all of the pins, however, this is only true when there is NO DEVICE ATTACHED. Why you ask?? Because there's not enough amperage to be an issue.. literally, 0.0028 - 0.03 A measured. That's far to low to do any sort of "damage" to an IC. it's far to low to even program an IC with. And guess what happens when you actually connect an IC to those pins.... The voltage instantly drops to 3v (when 3v is selected) The second thing i see people doing, and trying to blame the device for. They use the device for IC's at run on less than 3.3v, but they do so without using the adapter that drops the voltage to 1.8v (yes, there's an adapter for that) At the end of the day, the people opting to "mod" these devices are doing so because they haven't taken the time to understand the circuit they are working with, and making assumptions based on mere speculation. Both approaches are flawed. Take the time to reverse the circuit, and how it functions. the 3.3v/5v jumpers literally dictate what power is being fed tot he CH341A, and thusly, directly dictates what logic level the programmer is working on. The 4.x volts your multimeter is seeing on the pins when no IC is attached, is literally just the build-up charge in the capacitors, there is no amperage behind that voltage, and as such, there is no risk of corrupting, or damaging the IC's.

Actually useful. Computers would encounter a lot less problems if they reported the CMOS battery voltage level. 0.6v, yeah that's an indefinite bios reset right there.

Just a thought... how common are this kind of failure's? Do u think it has any tng to do with PCH and CPU being on the same chip? If so how concerned should i be coz i got msi modern 15 laptop with the same design... pch and cpu on the same chip. I've had it for a yr and its a nice laptop. With worst possible screen hinge designs...

You never needed volt mods for these... I've seen quite a few people modding these for absolutely no reason. There is no amperage on the lines that idiots are measuring and thinking they need to mod the device. You can't program with voltage alone, you need amperage as well... yes, some of the pins may read 4.xV, but at 0.02A, it's not harming anything (mainly because those high voltages only show up when there's zero load, and drop to near zero once a chip is socketed)

there is easy conversion from legacy mbr to gpt system to boot in uefi in windows 10 with simple command so you can convert your legacy install to uefi boot without losing your data. (backup still recommended as with any intrusive disk operation)

Good information even though it is 4 years old. On the topic of why someone would need 30A is charging larger battery packs. I have several 60V and 80V 5+Ah and larger packs that can take 10A+ for charging. Its still hard to find a desktop supply that will give me 82V for my biggest battery so I have even considered buying two 42V and running in serial.

Also Legacy boot is a must if you're using dual-boot for Windows and Linux. If you install a Linux it deletes the Windows entry from the UEFI. If you install Windows, it deletes all other entries. The only way to have both is Legacy boot with GRUB. systemd-boot can eat my ass.

I was running a HP Z230 and an HP 800 G1, the E3-1200 series Xeons are pretty good, the E5 xeons are not good for gaming as they tend to be low clock speeds, I had the E3-1246 V3 that is Haswell 4 core 8 thread 3.5 to 3.9ghz. with igpu. That probably has something like a X series or W3500 Xeon. I got too much time on my hands.

I don't think you noticed that when you changed to a legacy boot again the boot order was different. Now the SSD was first, where as before it was second. There could be a boot sector on that hard drive that was trying to load, but had no Windows it could find on itself.

Such precise and spot-on diagnostics! Incredible work! Just curios though if there is a reason that you would not perform a BIOS update ( this was on like A07 which sounds original since most Dells of that era made it to the A20's) and also just wondering if there is also a reason you would not convert the Legacy Win install to UEFI since it only takes a matter of minutes with the MBR2GPT utility? I have just got into the habbit on these older Dells of always doing BIOS update and convert to UEFI since it only takes an extra 5 minutes total and greatly improves compatibility and performance, especially with Windows 10... Just curious😃

I tend not to change setups unless I'm doing additional work with them. If windows had been scrambled and I was going to re-image it or clean install, I'd go to the trouble of updating everything. But in this instance, it's working, leave it alone. I've had instances with older machines where you start updating things, and then something changes or breaks, and you spend the rest of the day swearing at it and thinking "It was fine. It was working. It was finished. Why did I start meddling? I can't charge for any of this because none of it has anything to do with what the system came in for..."

@@Adamant_IT Thanks so much for the thoughtful and detailed reply! I definitely understand where you are coming from. I guess I just instinctively have PTSD after working on so many OptiPlex 9020 SFF machines that were so commonly found in hospitals, schools, law firms, etc that had the issue with the worst power supplies Dell ever manufactured and they turned into ticking time bombs if you left them on the earlier BIOS revs (A00-A03) and the PSU was on its way out, the combination was nuclear and the BIOS would eventually just go kaboom to the point where the machine would become nothing more than an office ornament, lol... I remember decommissioning an entire fleet of them for a law firm once and out of 25+, all but a handful had already gone nuclear to the point of no POST and the 4 or 5 that were left were all on original BIOS and I upgraded them all (I believe to A18 or A19 at the time, we are talking 13ish years ago...) and there all still running strong, with the exception of one of them which the power supply finally went out and all I had to do was order an upgraded power supply and slapped it in and it still worked fine even after being powered on the failing power supply which was the previous cause of the BIOS losing its brain cells, but because I had made it in time with the bias upgrade to the latest version, it definitely saved those BIOS chips from imminent destruction! Yes that's why if I see any Dell at boot up touting a bios revision in the A0x range, my PTSD kicks in and I am compelled to upgrade the BIOS to the latest version, but I guess this does only apply to Dell workstations from that era as I have not seen that particular issue with the 9020 SFF on any other mobo/PSU combo. But over the years I've definitely been able to save quite a few of those 9020 SFFs from the landfill by just doing a simple BIOS update. As for changing from legacy/mbr to UEFI/gpt, I guess I've also formed a habit and so far I guess I've just been really lucky because I have not had The conversion utility in Windows or the switching in BIOS ever cause any major issues. I guess I just made a habit out of it because in my opinion, Windows 10 performance is extremely degraded when a system is in legacy mode as you're introducing another layer for the operating system to route commands in and out of, whereas of course in UEFI, the system is able to just directly communicate with all the controllers and IO on the mobo... I think maybe my obsession is that anytime I see a Windows 10 system booting with the Windows logo instead of whatever the OEM manufacturer or mobo manufacturer's logo is, I guess it just sets me off because I know it's not right in my heart and I know that the fix only takes a matter of minutes, so if I leave it in legacy and don't switch to UEFI, every time I reboot the machine I just get more fueled when I see the Windows animated logo again at startup, lol... I always make sure that I do extensive research to confirm that the mobo for sure supports UEFI before I go down that road, lol...But I guess it's just a matter of myself ending up in your shoes where I'm doing a "simple" conversion from legacy to UEFI and things go south for no reason and then I would probably end up on your bandwagon of the more or less "if it ain't broke, don't fix it" mentality....🤦♂️😉
