Hi everyone, welcome to HowFixit.
In this video guide, I gonna show you how to disassemble Dell G7 7700 laptop, clean
it from dust and replace thermal paste.
To disassemble dell g7 7700 laptop, you will need the following tools:
Phillips 1 screwdriver Antistatic brush
Thermal grease Plastic opening tools
Tweezers I also recommend using a magnetic mat during
the repair process, which is especially useful in case of Dell G7 7700 laptop.
Throughout this disassembly, keep track of each screw so you can put them back in the
right places - this will help successfully reassemble your device.
And don't worry about losing any of screws, all of them will definitely remain on the
magnetic mat.
In the description, I left links where to buy all necessary tools.
Turn the laptop over and remove all the screws on the bottom cover.
Use a plastic tool to open the laptop case.
I recommend using a plastic tool so as not to damage the laptop case when opening it.
Disconnect the battery cable from the motherboard.
Now let's begin removing the cooling system.
Disconnect fan cables.
Let's begin cleaning the cooling system from dust.
Remove all dust from the heatsink and fan.
Remove all screws on the cooling system.
Pay attention to the order of removing the screws; I recommend unscrewing in the specified
order.
Now you can remove the cooling system by lifting up from the motherboard.
Remove the old thermal paste from the CPU and GPU as well as from the heatsink.
If the thermal paste is very dry and difficult to remove, you can use isopropyl alcohol to
wipe the paste.
How to apply thermal grease.
Apply a small amount of thermal paste to the CPU, then take a plastic tool and spread it
evenly over the entire surface of the chip.
If you still don’t know which thermal paste to choose for your laptop, in the description,
I left a link to a video where I test different thermal greases and choose the best one for
the laptop.
Now you can install the cooling system and tighten all the screws.
Please note: how I tighten the screws on the heatsink.
It is necessary to tighten the screws evenly on each side, with a few turns of each screw.
If you tighten the screw immediately and completely, there is a chance that you may damage the
processor chip.
If your Dell G7 7700 laptop is still overheating after cleaning and replacing the thermal grease,
I recommend watching my video about the cooling pad for the laptop, or how to undervolting
CPU and GPU to reduce heat and increase laptop performance.
All links you can found in the description.
Well, that's all, you were on HowFixit and see you guys next time!
