as the "original charger" was not working, I wrote the fa. in at Manchester. I was pleasantly surprised offered as me a second charger free and prompt sent wurde.das pitch was that also the second charger only intermittently worked hereby was unusable. since I started, but to doubt my Acer laptop .As the destination in forgotten original charger suddenly showed up I noticed that my laptop with its original charger perfectly charge read. my assessment must therefore be less unfortunately negative.
