3. Test on <90% charged battery without the adapter @ Full Brightness, Wifi+Bluetooth On, etc. (Max Performance)

4. Test on <90% charged battery WITH the 90W Adapter @ Full Brightness, Wifi+Bluetooth On, etc. (Max Performance)

5. Test on 100% charged battery WITH the 90W Adapter @ Full Brightness, Wifi+Bluetooth On, etc. (Max Performance) AND charging disabled in the BIOS

6. Test on <90% charged battery WITH the 90W Adapter @ Full Brightness, Wifi+Bluetooth On, etc. (Max Performance) AND charging disabled in the BIOS

7. And possible the most important one: repetition of tests 1, 4, 5 and 6 WITH a 130W Adapter.



* Be sure to check that your Power Management profiles have not automatically changed to a lower performance/maximize mattery life type profile.
** In tests 5 and 6 with battery charging disabled in the BIOS this naturally means that this setting (battery allowed to charge) is kept as default/factory settings in the previous tests.
I will be doing my own run soon, my 1645 was shipped yesterday. I'll probably receive it early next week.
