I would recommend you first drain the battery (or if that's not an option, simply shut down the laptop completely, take out the power lead of course and once you're inside the unit, disconnect the battery from the motherboard).
Its also preferable you use anti-static gloves when removing the bottom cover and working inside the laptop.
Next work on removing the heatsink.
Once you remove the heatsink, its a matter of simply cleaning the old thermal paste (use some Isopropyl Alcohol on a cotton stick and apply it gently to the old thermal paste until you remove it from both the CPU and GPU).
You should do the same on the CPU/GPU spots on the heatsink.

After that, ready your thermal paste (Thermal Grizzly Kryonaut for example or GC Gelid Extreme) and apply it to both the CPU and GPU.
The application of thermal paste will depend on the user really.
For laptops, I usually use a grain of rice blop in the center of the CPU and GPU dies and then I just apply the heatsink to allow the thermal paste to 'spread'.
However, various laptops come with very uneven heatsinks, so its sometimes better to spread the thermal paste in a very thin layer across the CPU and GPU dies yourself.

I'd also advise you to clean out the fans and exhaust vents from dust.

After you've done that, simply put the heatsink back into place by screwing it in place and close up the unit.

That should be pretty much it.
If I'm missing something, someone should chime in.

busu3 as it was already mentioned above im just reinforcing it u need a mobile phone disassembling kit (with the proper screwdriver tips to not damage any screws)  and pry tools isopropyl alcohol 99% cotton buds a brush kryonaut or similar (use the spread method only a thin layer covering both diodes its enough too much past its bad) and if the thermal pads arent damaged you dont need to replace them but if they are you need some  and patience also having your windows optimised and undervolted and keep the back lifted   good luck

Is the anti static gloves really required? If i keep the laptop on a wooden table would it still be affected by static discharge? Also will 70% alcohol be enough to clean the thermal paste? In some videos I noticed there was a tape connecting the fans to the motherboard, will that tape stick back when i paste it once am done? Thanks.

Another thing do I have to remove the hard disk and RAM sticks?

Anti-static gloves aren't strictly necessary. If you drain the battery entirely, or just disconnect it from the motherboard and press and hold the power button for 10 seconds after that to drain any excess charge from the electronics, you should be fine.

The anti-static gloves are just a recommendation. If you're working on wooden table, you should be fine.
70% alcohol should suffice. I used to use baby wipes to remove thermal paste from CPU/GPU dies without problems mostly, but applying the alcohol is advisable to clean it properly (and as I said, 70% alcohol should be just fine).

I'm unfamiliar with any tape connecting the fans to the motherboard. Usually, fans are screwed down to the motherboard and have a power cable connecting them to the motherboard [which usually need to be disconnected if you are cleaning out the fans and replacing the thermal paste], but they are not taped in. Once you open the unit, examine it to make sure the tape you speak of is not a ribbon tape of some kind (in which case you need to be careful on how you remove it).

No.
Unless you need to tear down the entire unit to reach some hw (which in this case shouldn't be necessary since your unit allows access to the CPU/GPU and cooling assembly by removing the back cover) you should not have to remove the HDD or RAM sticks (draining the battery, disconnecting it from the motherboard and then pressing the power button for 10 seconds to remove any excess charge from the electronics would suffice).

Ok thanks for the help!

busu3 i never used anything anti-static on any laptops/desktops its recommended but not required never had any issues and 70% alcohol should be ok in some countries its not available more than that and if you are repasting i always remove everything all drives (non m.2) and ram also remove the wifi adapter (because i completely disassemble everything to clean and repaste everytime) try to memorise where the black and white antenna cables are connected

Ok I will try that too. Thanks
