Update...again. In English. (it was Deepl helping with some technical language my basic German couldn't handle... Es tut mir leid) Used a 3A charger and noticed the battery percentage increase from 75% to 100% in about 1 hour. But battery icon does not show the battery is connected. Also laptop thinks it is still on battery. Tested in windows settings power and sleep. 4 minutes timer to switch off the screen on battery. 10 minutes time to switch off the screen on power. Screen switched off in 4 minutes. Battery was connected and charging during that teat Conclusion. The battery management software is not working as it should. (unlikely). The charge card is malfunctioning. The battery circuit is damaged. More information.... Using the laptop today on a 90% charge. After 4 hours normal use, (emails, Web, Google Docs and sheets), battery dropped to 62% and windows reports 7 hours remaining. Battery settings are set to mid way between Best Battery Life and Best Performance. Device manager shows Intel Battery Management Device and Microsoft AC Adapter drivers as being installed. Intel Battery Management Driver is installed with the chipset update from Medion Site (needed to install this to get touch screen working after fresh install of Windows) Disabled and enable both but nothing changed. Went into BIOS. No battery settings there, but left the laptop running for 22 minutes. Screen stayed on. Thanks for the help. Perhaps battery is ending its life and these are the symptoms? When the laptop was handed over with the request to see if it could be repaired, I beleive the batter had been discharged to zero for some time. Not good for a lipo battery I beleive. Thanks
