I have a Compaq Presario2100US laptop (Win XP, Serv. Pack 2) 1.6MHZ. It had 1 stick of PC2100 256MB memory. I ran a scan on the crucial website that showed a max allowable amount of memory of 1GB. I purchased a stick of PC2700 512MB of memory and installed in the open slot. The computer only read the new memory as 256MB. I tried taking out the old memory, but that didn't help. I also looked in the bios, but there isn't a memory setting that can be adjusted.
Any ideas?
Thanks
