You may have experienced that your Lenovo ThinkPad Carbon X does not power on any more. You exchanged the power adapter but it still does not power on. Well, the solution might be that it is mission an existential bios update about power management. You can revive your laptop by having a service provider unplug the battery for one minute and then plug it back in and the laptop may power one again. After that you have to goto the support website of lenovo and do all updates, which may take about 4 hours, amongst them the bios update.
