Ok, so ive been out today and bought a 1gb stick of ram to add to my sisters laptop, ive fitted it all good and theres also 512mb of ram in there aswell, however when i start up the laptop and i check how much is installed, it only shows up 898mb, i was thinking this could be the power supplies fault, what do you think?
It is not a power supply issue. its a motherboard issue. ur mother board can not read it all. ether the motherboard dont support 1g of ram or ur ports are fucked.
