Been awhile but I finally got me a nother laptop. HP Compac 8510w. Intel Centrino dual core 17500 @ 2.2 gHz, 2 gigs ram, 150 gig HD, 1920 x 1200 resolution screen, nVidia control panel. Ccleaner...MalwareBytes...MSE and everything is up to date. Sweet machine for $180.00 US refurbished. Win 7 Enterprise Edition. I don't know what that is, 64 bit. Gonna get back into stuff just as soon as I get it set up. Question...will my 320 gig HD from the other HP be compatible with this one. Can I swap it out?
