Lenovo T60 - durable battle tanks are quite a value nowadays down from their original MSRP - shipped with Core2Duo T2400 32 bit CPU with 2MB cache, still speedy enough for office use, but are limited to 3GB memory. The Zero-Insertion-Force Socket 478/N, Socket 479 or 'Socket N' - a simple half twist of the lock 'screw' releases the chip to lift away like a breeze and swap in this recommended replacement. The next chip up is the top t7600 which adds only the ability to overclock and are $40 or more. I found lot of 10 Core 2 Duo T7400 2.16GHz with 4meg cache running on 667MHz DMA bus at $10 each $11.50 with tax and shipping from China SpeedPak. While worth the wait I was surprised at half of the estimated month delivery. YouTube shows how simple it is to DIY swap. I vacuumed the fan/heat-sink while I had it out for the CPU replace - remember to scrub off the thermal paste residue & don't forget to reconnect the fan plug or get 'fan error' on boot. One can utilize existing memory but speeds will be limited unless rated above 666MHz - while you have it open swap 'em if you got 'em. For me the simple upgrade allows more powerful Win7Ultimate which dual boots with 64bit Ubuntu (easier to upgrade and far less intrusive as Win11 to my personal life) increases my software options. The CPU chip has a greater surface area and runs several Watts hotter so I'm glad my seller included a squeeze packet of thermal paste. Graphene is a superior heat conductor and I have a gallon of Slip/Plate #1 to drip onto the fresh cleaned CPU surface -more than I can use up in a lifetime but hard to remove completely when dry. Performance is not a straight comparison of 64bit v. 32 CPU as the memory is effectively halved because each memory location is now twice as wide yet the former. The old 3GB limit now recognizes 4GB so drop in 4GB (2x2GB) while I was in there. Choose 666MHz DDR 2 with 8 small RAM chips each side as opposed to 4 large per side as they are twice as efficient seek time. The real comparison comes by application - Teaching my grandchildren computing/programming/penetration-testing/networking. The revived e-trash has a modem, can burn a DVD, can go to class and take notes, docks with a huge variety of legacy devices and takes a bookbag/knapsack beating and keeps on running on. The original concept was to supply them each with a raspberry pi. For about the same price as fully outfitting a Pi with a keyboard and monitor et cetera for each kid. the price was a bit less to enhance existing laptops. I can USB LiveBoot any number of OS as with a Pi and any lessons learned from a Pi3+ can be learned by using the laptop to SHH into a headless Pi Zero. The backwards compatibility and wide utility of laptop upgrade cost less, is more versatile and durable enough to follow them through college. It might be taxed calculating astrophysics but a quiet durable keyboard and Notepad are all one really needs for a doctoral dissertation and for that the upgrade from T2400 to T7200 should outlast the application. ======== BOTTOM LINE =====eBay build out===== $11 CPU +$20 laptop + $12 0.5TB SSHD + $10 4GB mem +$14 battery +$7 charger + free Linux (w/ optional MSwin license = MegaTank for less than 3/4 C-note pro vs. con RPi dangle-wire outfit kit for slightly more.Read full review

My laptop had a T2300 CPU by default. I pulled into its socket the T7400 CPU and now I have a more powerfull laptop. It takes just 10 minutes.
