Sahil19 :
Thanks so much for the help! I also had some other questions.
1) Would upgrading the RAM improve the performance of the iGPU? Since it uses part of the ram, and
2) what is the difference between DDR3 and DDR3L?
3) Also looking at the document the specs aren't all the same, is that a problem?
4) and it also says "Switchable discrete graphics" so does that mean I can upgrade?
5) And if not, am I able to change the motherboard to have discrete graphics? (Sorry for all the questions)
1) Not really, though sometimes probably a bit. Faster RAM can help iGPUs a little bit in gaming, but your motherboard doesn't support anything faster, If however, you're running out of RAM and paging (which is certainly possible, even likely with the 4GB you have now), having extra RAM will help everything, including the iGPU. BUT, if you're wanting gaming performance, the iGPU will only ever do a mediocre job at
very lightweight games (SC2, LOL, etc).
2) DDR3L is low voltage (1.35V), DDR3 standard (1.5V). Most SODIMMS (smaller size usually for laptops) are the low voltage variant.
3) No, as long as I did actually link the correct model. You can use your service tag on the HP website to download the correct service manual for your laptop. You absolutely want the right document before you start disassembling it.
4) Don't start trying to add graphics... I'm sure some people have managed it at some point, but there are loads of issues with this. Cooling and power being just two of the key ones. Generally speaking, beyond storage and RAM, laptops should not be seen as upgradeable.
5) No
That is a portable laptop meant for office work. If you're trying to something other than that (like gaming), you might be able to make it marginally less terrible with a few upgrades, but that's the best you can hope for. You're very likely better off trying to sell what you have and get something better designed for what you're trying to do with it.
