No after multiple calls with Lenovo Tech support they determined this computer can NOT charge through USB-C Thunderbolt 4 port. I tried two very expensive Lenovo ThinkPad Docking Stations that have the capability to charge but there is an error from the computer. Don't buy this if you want to charge through Thunderbolt 4 port.
Sorry, there was a problem. Please try again later.I am confirming what DeanD responded with. This laptop, as of this writing, can only be charged using the supplied power adapter. I will take the response a step further and state that the charger uses a proprietary tip. So universal power chargers will not work. If you lose or damage it you will have to buy a Lenovo replacement. That being said, the charging and battery life are the only issues I have with this laptop. Everything else is phenomenal.
Sorry, there was a problem. Please try again later.The charger that comes with this is USB-C and the charger is a 140 watt charger.
