I have a dell e1505. windows 10 upgrade was halted do to x1400.
here is my workaround .
install windows 10 upgrade on another laptop ( i used my dell d630).
swapped the hard drive back into my e1505, and away you go.
windows 10 will use Microsoft basic display adapter , as the driver.
all functions and programs work.
some video may be choppy , but i can deal with that.
