Since my time with the laptop included power supply is (but of course only after the warranty) broke down after a short time, in my opinion, I have first a combined power supply of "Hama" fetched for different power connectors. Unfortunately, the given function - of several available plugs - also the weak point, so that the only-set-up plug and also the connection have wobbled so that you no longer moves the laptop best. So I again found me an original AC adapter. The plug - to connect to the laptop - fits perfectly again. The only annoyance is that the connection of the socket is for power supply from a power cable attached and is slightly loose in the power supply. In addition, I am How long because of the problems still skeptical effectively the power supply.
