[image] We’ve developed an RTC Battery Substitute module that can sit in place of the coin cell battery to keep the RTC circuit powered. Note that this does require soldering a single wire on the top side of the Mainboard. We are currently preparing the process for requesting this module, but ha…

[image] BigT: Technically, your OS should auto-correct the clock as soon as you connect to the internet Yup. I even do the overkill and run chrony on a consumer laptop… [image] BigT: but hey, and advantage is an advantage, lol And don’t discount lazyness – I’d have to work to undo the…

With the RTC Substitute solution, if the main battery is really dead / really low voltage / disconnected, then it’s essentially a mainboard reset. You immediately lose BIOS password, date / time, boot order, memory training…etc. (Yes, this board will not retain BIOS admin password on a mainboard r…

As I don’t see my latest post, I can easily assume you have removed it. So, in short, shorted the mainboard. In other words fried it. Ah well, lesson learned.

MJ1 Good advice. Too late, fried the sucker.

Finally installed it today. To be honest for me it was more difficult than the UltraHDMI mod I installed on my N64… The wire just didn’t want to stick. I can highly recommend magnifying glasses as well. Everything worked well except for the PTM7950 installation. I gave up after three tries (yes, I …

[image] Simon_Nienhaus: The wire just didn’t want to stick. Didn’t stick to what? Generally I’d approach it like this: Tin the wire with solder Add a small blob of flux on the capacitors on the mainboard Use tweezers to hold the tinned wire against the capacitors, as shown Tap it with a hot…

[image] Jonathan_Haas: Didn’t stick to what? To the solder. I’m not used to stranded wire. At least that’s what I think caused my issues. I could not get a blob of solder on the wire somehow. But I got there in the end.

[image] Simon_Nienhaus: To the solder. I’m not used to stranded wire. To be fair, the wire Framework uses seems to be pretty terrible. I’d have replaced it with solid core enamel wire, like it is used in inductors.

I have also come around to installing my RTC substitute module today and found it pretty easy. The most nerve wracking part was finagling the module into the RTC battery holder, as it seems to be about 0.5mm or so too thick and the holder is very fragile. The laptop booted right afterwards and eve…

[image] chrisp_chicken: I did not, however, remove the mainboard from the notebook and just did it in-place. I don’t endorse doing it this way, but for me it worked just fine. Yeah, I left the mainboard in place too. I fully removed the battery, but left the mainboard in place. I made a vid…
