1: hp laptops are easy to work on - one back panel and everything is accessible. Some screws are under the rubber feet 2: m.2 ssd is your storage, most likely a 2280 nvme, which is almost all of them. Open the laptop and measure the length of the ssd to confirm. They come in 80, 40, and 30mm lengths (2280, 2240, 2230). Get a 1TB minimum. 3: Upgrade that 8gb ram to 32gb (2x16gb). Assuming this is a clearance laptop with ddr4, that 8gb it has now is not enough for Win11 and daily use - Windows takes up to 5GB on its own, the remaining 3 will be eaten by a browser tab in chrome or firefox. In addition, your onboard graphics can eat up to 2GB of RAM as well, so you’re strangled by that small RAM amount no matter what. Don’t be shy about slamming more than you need - it’s future proofing. 4: look up your hp model on their website and get the service manual. It shows you how to rebuild the laptop from the frame up. Use this to figure out how to unbolt the back panel. 5: While you’re there, look at the specs - what kind of ram, how much it accepts, and what ssd it has.
