Here’s the proof you don’t need to upgrade the CPU in this old war horse below. Haswell is certainly a better CPU, but honestly, Ivy Bridge still has plenty of life in it. The chip in the P150EM is quite decent: The quad-core Ivy Bridge has a base clock speed of 2.7GHz and will Turbo Boost to 3.7GHz. If you’re concerned about battery life or do a lot of video encoding/editing, then yes, you might need the latest and greatest CPU. Much to Intel’s agitation, a lot of gamers really don’t need to stay with the fastest CPU if “all” they do is play games. The “Eurocom” P150EM is actually built by Clevo, which means the GPU upgrade for it should fit many other laptops too. With just the main hatch open though, you have full access to the GPU and CPU.

If this were a full upgrade, I might ditch the hard drive for an SSD, or at least also slot in an mSATA SSD into the available slot to improve my drive access times. There’s another door that covers the 2.5-inch drive too.

On the P150EM, remove four screws and slide off the bottom cover.
