Dell Inspiron 1501 laptop running 32bit Vista. Original memory consisted of 2 x 512 Mb chips and both the BIOS and Windows displayed 895Mb available to the system. Ran the Crucial.com scanner and that advised could upgrade to a maximum of 2Gb so ordered & installed the 2 x 1Gb chips to replace the original ones, the BIOS shows 1.9Gb available but when Windows loads still shows only 895Mb. I've reseated them, swapped them around, tried 1 x 512 and 1 x 1Gb in all combinations and still shows 895Mb in both Control Panel/System and in CCleaner's header.
Ran the Crucial scanner again and it correctly identified 2 x 2Gb chips installed, so I'm now at a loss.
One point that may be important is that I'm running it off of a generic power supply - the battery is U/S - and at the moment I'm having to 'press any key' at boot because the system down't recognise the type of power supply. I've ordered a new one but I don't know if this will have any effect.
Anyone have any ideas?
