Hello, Iets try to update the BIOS. Unplug all cables and remove the bottom cover. Unplug and remove battery. Unplug the CMOS battery for at least 1 minute and press the power button while all is disconnected for at least 20 sec. Watch this YouTube video  Reassemble the laptop. Try the BIOS Update afterwards again. Does this solve the problem? If so, disconnect the Docking Station and connect the power supply directly to the laptop. Pls post result.  Best regards  Peter              
Hi there, I have the following problem with my E7470. Symptom: Every now and then Windows 10 keeps shutting down ONLY when laptop is plugged to power supply. At some point the fan suddenly speeds up and the system gives the message: "shutting down" and then Windows shut down. This never happens when the laptop is only running on battery. It doesn't seem to be a temperature issue as sometimes it happens immediately after boot when the computer is running with no load at all. What I tried: - different power supply (tried 3 pcs) - same issue - removing the battery - same issue - different SSD with new Windows 10 - same issue Do you have any solution?
