hardware limitation. http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T60p-4gb-but-3-gb-available/td-p/11078 Dave, If I'm reading this correctly, it looks like the system is using all 4g. What do you think?

Dave, Thank you for your response. The rest is not present? Mapped by the BIOS? Mapped by the OS? It's been suggested that I have a BIOS problem and should upgrade. THANKS again, George... it's a hardware problem. It can't be fixed. The way the chipset has been wired will only address a maximum of 3G of memory. The other 1G is lost. Dave, Ok. Thank you so much for your help and patience. Regards, George... |
