I thought that I read somewhere that the new cpu now are at 4ghz or 5ghz now. Which cpu are they.
Commercially available desktop processors are available at 4GHz and faster: http://www.newegg.com/Product/ProductLi ... erSearch=1
In the T420 what size hard drive that fit in it is it a 2.5 or is it smaller then a 2.5 inch drive.
It would fit a 2.5" drive that is 9.5mm (or less) in height.
On this T420 where is the Bluetooth card at?
One of the biggest advantages of a ThinkPad is that Lenovo produces detailed service manuals that list every part and how to completely disassemble and reassemble the unit. That manual has the answer.
I see that there are driver for it but I can't get the Bluetooth to work.
Make sure the Bluetooth module is installed, enabled in the BIOS Setup, turned on via the Hotkey Features Integration software, and you have the latest drivers installed. Scott.
