legion5i Can I clean my laptop with a vaccume cleaner?

[Mr.Stork]

I recently bought my first ever laptop, Lenovo Legion 5i, 3 months ago and the dust has been building up on the back panel vents, we usually have excessive dust in India, and before it becomes too much I wanna know how to clean it as I have never owned a laptop before I don't know much about cleaning one.

 

So can I blow or suck using laptop without opening the laptop back?

Should I use a brush to brush off the dust? Does opening the back void warranty? Also, does changing parts like ram and ssd void warranty? (Slightly offtopic).

 

If you can please share more details other than the questions I asked if you feel like I need to know. Thanks.

Maybe take look at what people talked about here: Laptop & Desktop cleaning tips anyone ?

and yes you can use vaccume cleaner but i would never recommend it, because you could kill your hardware(static charge), compress air is one of the best solutions in my opinion.

To properly clean out the laptop you need to open it. Otherwise you just blow the dust into the laptop and it will be sucked back to the vents. The legion 5 is easy to open so that isn't a problem.

 

The general rule with a vacuum cleaner is to not suck as that does generate a bit of static electricity. How I always clean laptops is use of compressed air, compressed air cans or something that blows a powerfull gust of air through a small nozzel (max 2bar of pressure as more can hurt a system by accident). Then use a brush to clean the fans and heatsinks + blowing some air interchangeable or at the same time depending on how hard the dust is to remove. It is ok if some stays just that the biggest parts are gone. So a vacuum cleaner with a blowing function is fine as long as the air can be concentrated a bit as otherwise it won't do much.

 

Warranty should not be void by opening a device or changing out parts. This does depend on your country. Always change things back to stock when sending it for warranty as it can either be rejected, the parts be removed or you lose the laptop + your added parts.

Possibly also depends on the model. For example my laptop's manual explicitly mentions that the drive and RAM is user serviceable. A previous model had two RAM sticks, one behind a cover, the other below the keyboard. The manual explicitly stated that the second one was not user serviceable (didn't stop me from replacing it though).

 

For a model where stuff is soldered I'd say the answer is a clear yes (voids warranty).

It's better to open the laptop and cleaning it by blowing air instead of vacuum cleaning it, because if you just vacuum cleaning it through ventilation hole there a chance not all of the dust get sucked
