Unlike the slightly older sibling, the AH502, AH512 with matte display but has a glossy display!
I run the device under Windows 7 and am impressed by the long battery life of about five hours. An earlier problem with the complete discharge of the battery when the notebook is turned off for more than a week and disconnected from the mains [230 V] remains, the manufacturer has in the meantime also dissolved (keywords: "Anytime USB Charge" & BIOS / Ver 1:16.)
Small drawback: The laptop has no USB3, but only USB2 and the mouse buttons make a slightly sagging impression.
My experience with the vendor support are good: Fujitsu was able to solve my problem geschildertes competently with the complete discharge of the battery.
I bought in the meantime two AH502 and AH512 and a shared within the family.
