Xiaomi RedmiBook 9 Pro is a popular model among users who value performance and accessibility. However, even the most reliable device requires maintenance over time: dust clogs the ventilation grilles, the thermal paste dries, and the keyboard accumulates dirt. Untimely cleaning leads to overheating, reduced performance and even breakdowns. This article will help you understand how to properly clean the RedmiBook 9 Pro laptop at home – from tool preparation to thermal paste replacement.
We will consider not only basic dust cleaning, but also nuances specific to this model: design features, cooling system weaknesses and recommendations for care. IPS-It's important to remember that the RedmiBook 9 Pro has a non-shattered battery and brittle plumes, which puts limits on the disassembly process. If you've never cleaned your laptops yourself, carefully study all the warnings and prepare your workplace.
Preparation for cleaning: tools and safety measures
Before you start, gather the necessary tools. RedmiBook 9 Pro will require:
- 🔧 Screwdriver kit: cross PH00 flat for plastic latching
- 🧴 Alcohol napkins (70-90%) oropropyl
- 🖌️ A brush with soft pile (suitable for watercolor)
- 💨 Compressed air cylinder (do not use a vacuum cleaner!)
- 🧴 Thermopaste (e.g. Arctic) MX-4 noctua NT-H1)
- 📱 Plastic mediator for disengaging the body
Important: work on a table with good lighting. Put your laptop on a soft cloth so you don't scratch the case. If you have long hair, tie it up -- getting a hair on the motherboard can cause a circuit. Also prepare the screw containers: RedmiBook 9 Pro uses screws of different lengths, and entanglement will damage the case.
⚠️ Warning: Do not start disassembling if the laptop was turned on less than 30 minutes ago. capacitors on the motherboard can keep the charge. Also make sure the battery is turned off (this model requires the physical disconnection of the plume).
Disassembly of the body: step-by-step instructions
The RedmiBook 9 Pro is supported by 12 screws and plastic latches. Start by turning off the power and removing the bottom cover:
- Turn over your laptop and unscrew all the screws (they are hidden under rubber legs - gently tuck them in).
- Start on the right side: insert a plastic mediator into the gap between the top and bottom of the case.
- Carefully drive the mediator along the edge, disengaging the latches. Do not force - if the body does not respond, check if all screws are twisted.
- After removing the cover, disconnect the battery plume (it is under a black insulation tape).
In the RedmiBook 9 Pro, the touchpad plume runs under the battery — it can't be detached without completely removing the battery. Unless you're planning to replace the thermopaste, just clean the dust without touching the motherboard.

Cleaning the cooling system and cooler
The main problem with the RedmiBook 9 Pro is the rapid dusting of the radiator due to its compact body.
- Take off the cooler (4 screws) Be careful - its cable is short and fragile.
- Remove dust from the blades with a brush, then blow the radiator with compressed air on the back side (so that the dust flies outward, rather than deeper into the body).
- Wipe the radiator with an alcohol napkin. If the thermopaste has dried (darkened and became hard), it should be replaced.
To replace the thermal paste:
- 🧪 Carefully remove the old paste with a napkin.
- 🎨 Apply a new paste in a thin layer (about the size of a pea) on the processor and chip of the graphics card.
- ⚠️ Do not use metal objects to remove old paste – it will scratch the CPU crystal.
| Symptoms. | Reason. | Decision |
|---|---|---|
| The laptop is very warm when loaded | Dust in the radiator or dried thermopaste | Cleaning + Replacement of thermopaste |
| Cooler operates at maximum without load | Faulty thermal sensor or clogged air channels | Diagnostics of the sensor or complete disassembly |
| The laptop is turned off when playing | Overheating due to inefficient cooling | Cleaning + Possible Cooler Replacement |
💡
If the cooler is still making noise after cleaning, check the bearing. RedmiBook 9 Pro often has a backlash fan problem - in which case a cooler replacement is required.
Cleaning the keyboard and touchpad
The RedmiBook 9 Pro keyboard is backlit, so you can't clean it with wet wipes.
- 🖌️ Dry brush to remove crumbs between keys
- 💨 A compressed air canister (hold it vertically so as not to freeze the plastic)
- 🧴 A napkin soaked in alcohol (crush it so that liquid does not drip)
You can take the keys off for deep cleaning, but in this model, they're attached to fragile plastic latches. If you're not sure about your skills, you better go to the service. The touchpad is cleaned just like the keyboard, but avoid pressing too hard, because there's a plume underneath.
⚠️ Warning: If the keyboard becomes stuck after cleaning, check if moisture has fallen under the membrane.This requires a complete drying within 24 hours (the laptop must be turned off and the battery is off).
Screen and body cleaning
RedmiBook 9 Pro screen has an oleophobic coating that is easily damaged with aggressive detergents.
- Turn off your laptop and let the screen cool.
- Use microfiber cloth soaked in distilled water (don't press hard).
- To remove greasy spots, use special wipes for monitors (without alcohol!).
The case can be wiped with a damp cloth with a drop of dishwashing agent (not abrasive!). Avoid getting moisture into the vents and connectors. USB-Ports use a toothpick dipped in alcohol.
What can not clean the screen
Assembly of a laptop and checking of working capacity
After cleaning, assemble the laptop in reverse order:
- Connect the battery plume (make sure the connector sits tight).
- Install the bottom cover, starting with the latches near the touchpad.
- Twirl the screws cross-cross to avoid skewing the body.
Before activating, check:
- 🔌 All connectors are connected (especially cooler and speakers).
- 🔊 Are there any extraneous sounds when the cooler is rotating.
- 🌡️ The temperature of the processor in HWMonitor (must be no higher than 45)°C to the plain).
If the laptop does not turn on after assembly, check:
- Is the battery plume connected?
- Will the cable be hushed somewhere (a frequent problem with careless laying of the touchpad plume).
- Whether all screws are twisted (the missing screw can block the motherboard's contact with the body).
💡
If the processor temperature has not dropped after cleaning, it may be necessary to replace the heat pads on the VRM chips (they are located next to the processor and also warm up).
Prevention: How to Clean Your Laptop Less Often
To keep the RedmiBook 9 Pro clean for longer:
- 🖥️ Use a laptop on a hard surface (not on a bed or sofa).
- 💨 Blow the ventilation holes with compressed air regularly (once in a week). 2-3 month).
- 🚫 Don’t smoke near your laptop – the tar quickly clogs the radiator.
- 📦 Keep the device in a case when not in use.
It is also recommended that:
- 🔄 Update. BIOS (In new versions often improve control of the fan).
- 🛠️ Use temperature control software (ThrottleStop or HWInfo).
- 🔋 Every six months, disassemble your laptop for preventive cleaning (even if there are no visible problems).
If you live in a dusty room or have pets, you will have to clean more often, in which case you should consider installing an additional filter on the ventilation grilles (sold in computer stores).
