Attempting to upgrade my laptop is the plan. They share the same socket, but my model is really old. It's an HP Pavilion G6. I'm hoping for help, and if it doesn't work, I'll just give it away. Will the new CPU fit? Updated January 1, 2023 by XsunaTera66 — question answered (kind of).
You cannot modify laptop components in that way, since they are typically fixed and soldered onto the board 99% of the time.
It wasn't soldered, so I took it out to reapply thermal paste before
Did you take out the cooler? You’re not removing the CPU to change thermal paste. Unless you can actually detach the CPU, most laptop motherboards and CPUs are soldered—even after a BIOS update they usually won’t work. Swapping CPUs for laptops is only new lately unless you had a desktop-style setup with a board and CPU inside. That wasn’t common for Sandy Bridge or Ivy Bridge models.
During the Sandy Bridge period, these processors were likely installed in sockets rather than soldered. However, there could still be issues with chipset or BIOS compatibility. Upgrading from such an outdated chip to a newer one might not be a good idea. For a used laptop from that time, lightweight Linux distributions seem like a practical choice.
It’s going to be slow even after the upgrade. Replacing the old spinning HDD with an SSD can improve speed for everyday tasks without breaking the bank, but you won’t be able to play games on this machine.
I thought getting an SSD would help since the new HDD isn’t working. The HD4000 can’t handle it either. It also doesn’t support the latest generation. The BIOS won’t work with it. You might save around $200 and get an 8th-gen laptop with a basic MX330, which should get you started. It’s not perfect, but it will function.
