Hi, my 3year old lenovo t440p laptop shuts down after few seconds when it's attached to AC and battery is inserted. It also does not start up when the battery is inserted and connected to ac power. It's running fine when connected to ac power and battery removed. I tried my charger and battery on another laptop and they are working, I'm experiencing the same issue when using different battery and charger. I tried to push power button for 11th times and WA like this but no luck. I was thinking to update the BIOS, but I'm not sure if it possible without battery..
