However, over time, any laptop requires maintenance: cleaning from dust, replacing thermal paste or hard drive. Disassembling this model has its own peculiarities, which you should know about in advance, so as not to damage the fragile connectors or break the plastic latches.
In this article you will find step-by-step instructions with photos, a list of necessary tools, as well as typical beginner mistakeswhich lead to breakdowns. We will analyze not only standard disassembly for cleaning, but also the nuances of access to the motherboard, cooling system and battery. We will pay special attention The unique design of the keyboard mounting in this model is different from most laptops Acer that period.
Preparing for Disassembly: Tools and Precautions
Before you start disassembling Acer Aspire 5750G, prepare your work area and tools. You will need:
- ✅ Phillips screwdriver
PH0(small, for laptops) - ✅ Plastic spatula or pick (to separate the latches)
- ✅ Tweezers (for removing small screws)
- ✅ Thermal paste (if you are planning a replacement, for example,
Arctic MX-4) - ✅ Antistatic wrist strap (optional, but recommended)
- ✅ Containers for screws (to avoid confusion during assembly)
Important: Aspire 5750G has Hidden screws under rubber feet - they are easy to miss, which will damage the housing when trying to remove the cover. Also, this model uses screws of different lengths, so record their location (eg take photos before removing).
⚠️ Attention! If the laptop was turned on before disassembling, allow it to cool for at least 30 minutes. Contact with hot components (especially the radiator) can cause burns. Also, do not touch the motherboard without an antistatic wrist strap - static electricity often damages the south bridge in laptops Acer 2010-2012.

Removing the back cover and accessing the main components
Start by unplugging your laptop and removing the battery. B Aspire 5750G The battery is secured with two latches - slide them to the sides, then pull the battery up. Next:
- Turn the laptop over and remove all the rubber feet (there are screws hidden underneath them).
- Unscrew 11 screws on the back cover (note: 2 screws are shorter than the others - they secure the hard drive).
- Using a plastic spatula, carefully pry the cover off, starting at the corner near the power connector. The latches are fragile!
After removing the cover you will have access to:
- 💾 Hard drive (
2.5" SATA) - 🖥️ RAM (
DDR3 SO-DIMM, 2 slots) - 🔋 Cooler and radiator (partially)
- 📶 Wi-Fi module (
Mini PCIe)
If the screws do not come off, do not force the Acer Aspire 5750G Threaded inserts often get stuck. Try a drop WD-40 or lightly heat the area with a hairdryer (no higher than 60°C).
To fully access the cooling system and motherboard, you will need to remove the keyboard and top panel - we will talk about this in the next section.
Disassembling the top panel and keyboard: hidden traps
Keyboard in Aspire 5750G it is attached in a non-standard way: in addition to the latches around the perimeter, it is fixed two screws under the screen frame. Many users break the latches when trying to remove the keyboard without first removing these screws.
Procedure:
- Unscrew the 2 screws under the top frame of the screen (they are hidden under the caps).
- Using a plastic spatula, carefully pry up the keyboard, starting in the upper right corner.
- Disconnect the keyboard cable from the motherboard (the connector is secured with a latch).
After removing the keyboard you will see:
- 🔧 Motherboard mounting screws (4 pcs.)
- 🖱️ Touchpad cable (carefully disconnect)
- 🔊 Speakers (attached with double-sided tape)
⚠️ Attention! B Aspire 5750G The touchpad cable runs under the motherboard. If you plan to remove it, first disconnect this cable - otherwise you may break the contacts when lifting the board.

Cleaning the cooling system and replacing thermal paste
Cooling system in Acer Aspire 5750G - one of the weakest points of the model. Dust clogs the radiator after only 1-2 years of operation, and the factory thermal paste dries out, which leads to overheating. To clean and replace thermal paste:
- Unscrew the 4 screws securing the cooler (they are spring-loaded - don’t lose the washers!).
- Remove the heatsink from the processor and chipset. Be careful: thermal paste may stick to the crystal.
- Clean the radiator and fan from dust using a brush and a vacuum cleaner (do not use wet wipes!).
- Apply a thin layer of new thermal paste (~0.5 mm thick) to the processor and chipset.
Recommended thermal pastes for this model:
| Thermal paste | Thermal conductivity | Service life | Price (for 3g) |
|---|---|---|---|
Arctic MX-4 | 8.5 W/mK | 4-5 years | ~500 rub. |
Noctua NT-H1 | 8.9 W/mK | 3-4 years | ~700 rub. |
Thermal Grizzly Kryonaut | 12.5 W/mK | 2-3 years | ~1200 rub. |
DeepCool Z5 | 7.5 W/mK | 5+ years | ~300 rub. |
What happens if you don't clean the cooler?
A radiator clogged with dust reduces cooling efficiency by 40-60%, which leads to:
- Constant processor throttling (performance drop by 30-50%)
- Accelerated wear of the video card (in Aspire 5750G discrete is used NVIDIA GeForce GT 540M, sensitive to overheating)
- Failure of capacitors on the motherboard (a typical problem for laptops Acer 2010-2013)
After replacing the thermal paste, reassemble the cooling system in reverse order. Tighten the radiator mounting screws criss-crossto avoid skew.
Replacing the hard drive and RAM
Acer Aspire 5750G supports up to 16 GB DDR3 (2 slots) and hard drives 2.5" SATA III (or SSD). For upgrade:
Replacing HDD/SSD:
- 🔧 Unscrew the 2 screws securing the hard drive (they are shorter than the others!).
- 🖥️ Pull the drive away from the SATA connector (do not force it - the connector is fragile!).
- 💾 To install the SSD, use an adapter-sled (usually not included with the drive).
Replacing RAM:
- 🔧 Press the latches along the edges of the slot.
- 🖥️ Insert the memory bar at an angle of 30° and press until it clicks.
- ⚠️ B Aspire 5750G dual-channel does not work if the slats are of different volumes.
Compatible memory modules:
| Manufacturer | Model | Volume | Frequency |

| Kingston | KVR16S11S8/8 | 8GB | 1600 MHz |
| Samsung | M471B5273DH0-CK0 | 4GB | 1333 MHz |
When replacing HDD with SSD in Acer Aspire 5750G Be sure to update your BIOS to version 1.25 or later - older versions do not support drives larger than 1 TB.
Common mistakes during disassembly and how to avoid them
Even experienced users make mistakes when disassembling Aspire 5750G. Here are the most common:
- Broken keyboard latches - occurs due to an attempt to remove the keyboard without unscrewing the screws under the screen frame. Solution: Always check for hidden fasteners.
- Torn touchpad cable — the cable runs under the motherboard and is often forgotten when removing it. Solution: Disconnect the cable before lifting the board.
- Overtightened radiator screws - leads to cracks on the motherboard. Solution: Tighten the screws with a torque of no more than 0.6 Nm.
- Lost rubber feet — without them, the laptop will “walk” on the table. Solution: Glue them with double-sided tape before assembling.
Another typical problem is incorrect assembly after replacing thermal paste. If you forget to connect the cooler to the motherboard, the laptop will not turn on (overheating protection). Check all connectors before final assembly!
Assembling a laptop: checking and testing
Collect Acer Aspire 5750G in reverse order, following these tips:
- ✅ Make sure that all cables are connected tightly (especially the keyboard and touchpad).
- ✅ Check the fastening of the Wi-Fi antennas - they should fit tightly to the lid.
- ✅ Tighten the screws without fanaticism: in a plastic case it is easy to break the threads.
- ✅ After assembly, turn on the laptop and check the temperatures in
HWMonitor.
Normal temperatures for Aspire 5750G after cleaning:
- 🌡️ Idle: 40-50°C (processor), 35-45°C (video card)
- 🎮 Load: 70-85°C (processor), 65-75°C (video card)
If temperatures are above normal, check:
- 🔧 Correct application of thermal paste (there should be no bubbles).
- 🖥️ The tightness of the radiator to the processor.
- 💨 Fan operation (should spin without extraneous sounds).
After replacing the thermal paste, let the laptop work for 2-3 hours in normal mode - the thermal paste will “settle” and the temperatures will stabilize.
FAQ: Frequently asked questions about Acer Aspire 5750G disassembly
Is it possible to replace the discrete video card in this model?
No, NVIDIA GeForce GT 540M soldered to the motherboard. The only way to improve graphics is to use an external video card via ExpressCard (but this requires additional adapters and is not always justified).
How to remove the screen if the matrix is cracked?
The screen is secured with 4 screws under rubber plugs in the lower corners. After unscrewing them, carefully pry up the frame with a plastic spatula (starting from the bottom edge). The matrix cable is secured with a latch - do not pull the wires!
The laptop does not turn on after assembly - what to do?
Check:
- Connecting the cooler to the motherboard (connector
CPU_FAN). - The tightness of the RAM (try reinstalling the strips).
- Power button - sometimes it gets stuck after disassembly.
If that doesn't help, reset the BIOS (remove the battery for 30 seconds).
Which thermal paste is best to use for long-term effect?
For Aspire 5750G optimal:
DeepCool Z5- the most durable (5+ years), but slightly less effective.Noctua NT-H1- the best balance of price and quality.Thermal Grizzly Kryonaut- the most effective, but requires replacement every 2 years.
Avoid cheap thermal pastes (eg. KPT-8) — они высыхают за 6-12 месяцев.
Is it possible to install two SSDs instead of an HDD and a DVD drive?
Yes, but you will need an adapter for DVD drive (For example, NBM mSATA to SATA). Please note that the second SSD will operate in SATA II (up to 300 MB/s) because the DVD-ROM connector is connected to a slower controller.
