About JCRM87

Hi all; I have a Medion E4271, it's a simple laptop that I use mostly for work but also for some light gaming. Recently I installed an SSD (it was very easy, M2 accessible without needing to open the whole thing) and reinstalled Windows 10 in it. The problem I'm having is that the laptop won't start up if it's not plugged in. Once plugged, it starts and runs perfectly but if I unplug it, it will shut down immediately. Surprisingly, if I plug it back in and start it, everything continues pretty much as if nothing happened, just a soft restart. After the Win10 reinstall, every driver seemed to install itself pretty quickly and easily, even the touch controls (the laptop has a touchscreen) but it seems like the battery manager is screwed somehow. Things I've tried: Turning it off, holding Power for 30 seconds, starting it. Nothing changes. Updating battery drivers, Win10 finds nothing. Changing energy plans, everything seems fine, and even after changes the problem persists. Looking for new drivers on the manufacturer's website. Nothing for my model. Things I haven't tried: Updating the BIOS: I have a bad experience from a different laptop and I'm a bit afraid. Could this fix it? Is there any foolproof way, app, or tutorial somewhere? Opening it up, fiddling with the battery. I'd rather avoid this. The battery is built in a solid metal casing. Installing the M2 was easy because of the dedicated port, but that's it. NOTE: I really doubt this is a battery issue. The battery ran perfectly before the windows reinstalling. Also like I said, installing the M2 SSD was super easy. It has its own port so I doubt anything got damaged internally. ... View more
