Chosen Solution
hi forum i have recently bought a lenovo u510 which runs average but i want to upgrade the cpu it’s currently a Intel core i7-3537U 2,00GHz
U Series chips are always soldered :-(. No, it can’t be done. The good news is you bought an i7 system, so you don’t have a poorly aged i3 that’s EOL over a soldered CPU. The problem is they’re designed for thin and lights, but got abused in recent years and put in everything. So now you have this dumpster fire of soldered laptops that are compromised which wouldn’t have been if a normal CPU was used when it was a normal machine.
If you have not already done it, replace hard disk drive with a SSD drive and increase the RAM. https://www.how-fixit.com/laptop-repair-… and then upgrade all drivers. This will produce a much more dramatic improvement in performance than upgrading CPU or GPU, especially the SSD.
