Thinkpad T490s No battery recognize
I just bought a new T490s battery. The Lenovo Diagnostic said no battery. Open check the battery socket from motherboard it shows no voltage should be 11-12V. The usb-c power adapter had 20v and the laptop came up with ac adapter plug in. What should I check next?
