Disassembling the Lenovo G570 laptop: a complete guide with photos and secrets

Laptop Lenovo G570 is a popular model from the early 2010s that is still used by many users. Over time, any laptop requires cleaning, replacing thermal paste or upgrading components, but not everyone knows how to properly disassemble it without the risk of damaging fragile parts. This article will help you understand the intricacies of the process: from preparing tools to dismantling key components.

It is important to understand that laptop disassembly - it's not just about unscrewing screws. There are pitfalls here: hidden latches, fragile cables and non-obvious fastenings. For example, at G570 The plastic clips on the keyboard cover often break if you try to remove it without knowing the design. We will analyze each stage in detail so that you can avoid common mistakes.

Preparing for Disassembly: Tools and Safety Precautions

Before you start disassembling Lenovo G570, make sure you have everything you need. Without the right tools, you risk damaging the case or internal components. Here is the minimum set you will need:

• 🔧 Screwdriver set: cross PH0 (main), flat 2.5 mm (for prying latches), Torx T5 (for some screws)
• 🧲 Magnetic mat or container for screws (so as not to lose small parts)
• 📸 Smartphone for photographing disassembly stages (useful for reassembly)
• 🧴 Alcohol and lint-free cloth (for cleaning contacts if necessary)
• 🔌 Anti-static wrist strap (optional, but recommended to protect electronics)

Pay special attention power outage. Even if the laptop is turned off, the capacitors on the motherboard can retain their charge. To completely de-energize the device:

1. Turn off the laptop and disconnect the power supply.
2. Remove the battery (to G570 it is removed after snapping off the two latches on the bottom cover).
3. Hold down the power button for 10-15 seconds - this will discharge the residual capacitors.

⚠️ Attention: If you are disassembling your laptop to replace thermal paste, do not use metal spatulas to remove the heatsink! Aluminum fins are easily deformed, and the copper base can break off. It is better to use a plastic pick.

Removing the bottom cover and accessing internal components

Let's start by dismantling the bottom panel. U Lenovo G570 it is secured with 11 screws: 9 under the rubber feet and 2 under the battery. It is important to unscrew them in the correct order so as not to deform the case:

1. Turn the laptop over and remove the battery.
2. Carefully pry up the rubber feet (they are glued, but can be removed without damage). The screws are hidden underneath.
3. Unscrew all the screws, starting with the corner ones, then along the perimeter. Don't unscrew them completely - leave in the holes so as not to confuse the length.
4. Use a flathead screwdriver to pry the cover along the seam (starting at the corner near the battery) and slowly separate it from the body.

Under the cover you will see:

• 🖥️ Motherboard with processor and chipset
• 💾 Hard drive (2.5" SATA) and DVD drive bay
• 🔋 Battery connector
• 🌡️ Cooling system (radiator + fan)
• 📶 Wi-Fi module (mini PCIe)

⚠️ Attention: When removing the cover, do not pull it sharply upward - the touchpad cable is attached to it! First, carefully disconnect it from the motherboard by pulling the black tab on the connector.

Take photos of the location of the screws and cables|Disconnect the battery and discharge the capacitors|Use an antistatic wrist strap or periodically touch a grounded object|Do not touch the connector pins with bare hands (risk of static discharge)|Mark the different lengths of screws (e.g. with sticky notes)-->

Removing the keyboard and top panel

Keyboard on Lenovo G570 secured with 3 screws (under the cover) and many plastic latches. To remove it:

1. Remove the 3 screws on the top of the case (they are marked with a keyboard icon).
2. Carefully pry up the keyboard with a flathead screwdriver, starting at PgUp/PgDn (there are fewer latches).
3. Lift it and turn it over - you will see a train. Disconnect it by pulling the white tab upward.

Hidden under the keyboard:

• 🔑 Power button (soldered to the motherboard)
• 🎛️ Touchpad and indicator cables
• 🔊 Speakers (attached with double-sided tape)

Important: on some revisions of the G570, the keyboard cable is glued to the case with hot-melt adhesive. Do not pull it by force - heat it with a hairdryer (60–70°C) and carefully separate it.

To completely dismantle the top panel (if matrix or hinge replacement is required):

1. Remove the screen frame by prying it off with a plastic spatula (starting from the bottom corner).
2. Unscrew the 4 matrix mounting screws (2 on each side).
3. Disconnect the matrix cable (it is secured with tape - do not tear it!).

Disassembling the cooling system and replacing thermal paste

Cooling system G570 - one of the most vulnerable places. Over time, the thermal paste dries out and the heatsink becomes clogged with dust, leading to overheating. To clean it and replace thermal paste:

1. Unscrew the 3 screws securing the cooler (they are spring-loaded - don’t lose the washers!).
2. Carefully remove the heatsink, rocking it from side to side (the thermal paste may have “stick”).
3. Clean any remaining paste from the processor and chipset with alcohol. For GPU use lint-free cloth — his crystal is fragile!
4. Apply new thermal paste (eg Arctic MX-4) in a thin layer (the size of a pea).

To clean the cooler:

• 🌀 Remove the fan from the radiator (by unscrewing 4 screws).
• 🧹 Remove dust with a brush or a can of compressed air.
• 🛠️ Lubricate the fan bearing with silicone grease (1 drop in the center of the sticker).

⚠️ Attention: If after assembly the laptop does not turn on, check whether you forgot to connect the cooler power cable (thin white connector next to the radiator). Without it, the system will shut down due to overheating after 5–10 seconds.

Replacing components: what can be upgraded in the G570

Lenovo G570 - not the most upgradeable model, but some components can be replaced:

• 💾 Hard drive: Instead of HDD you can install SSD 2.5" SATA (up to 1 TB). To do this, you will need an adapter for mounting (the holes in the HDD basket do not match).
• 🖥️ RAM: Maximum - 8 GB (2 sticks of 4 GB DDR3-1066). Modules from Samsung, Hynix And Kingston.
• 📶 Wi-Fi module: Can be replaced with a more modern one (for example, Intel 7260 with support 802.11ac), but driver modification will be required.
• 🔋 Battery: Original batteries (L11M6P21) are no longer produced, but there are analogues from Camelion or Green Cell.

What it's impossible replace:

• ❌ Processor: soldered to the motherboard (models with Intel Core i3/i5 2xxx).
• ❌ Video card: integrated Intel HD 3000 or discrete NVIDIA GT 520M (also soldered).
• ❌ Matrix: only similar (resolution 1366×768, connector eDP 30-pin).

If you plan to install an SSD, keep in mind that the BIOS G570 no mode AHCI default. To enable it:

1. Boot into BIOS (button F2 when turned on).
2. Go to Advanced → SATA Mode.
3. Select AHCI instead of Compatibility.
4. Save the settings (F10) and reinstall Windows (if you change the mode, the system may not boot).

Typical problems during disassembly and how to avoid them

Even with careful disassembly Lenovo G570 You may encounter unexpected difficulties. Here are the most common of them and ways to solve them:

Another common mistake is damage screen hinges when replacing the matrix. On G570 it passes through the right side of the body and often frays. If vertical stripes appear on the screen after assembly, check:

• Integrity of the cable (no kinks or breaks).
• The tightness of the connector to the motherboard.
• No dust in the connector (sometimes it is enough to blow it with air).

If the laptop starts turn off spontaneously after disassembly, the reason may be:

• 🔌 Faulty battery (check the voltage with a multimeter - it should be ~ 11 V).
• 🌡️ Overheating (make sure the cooler is spinning and the thermal paste is applied correctly).
• 🔌 Poor contact in the power connector (move the power supply - if the laptop turns on, soldering is required).

Assembling a laptop: reverse order and check

Assembly Lenovo G570 should proceed in the reverse order, but taking into account several nuances:

1. Trains: Connect them last so as not to interfere with the installation of the cover. Start with the keyboard cable, then the touchpad and matrix.
2. Screws: Screw them crosswise (like the wheels of a car) to avoid distortion of the body.
3. Cooler: Before installing the heatsink, make sure that the thermal paste does not get on the resistors around the processor.

After assembly, check:

Test your keyboard (all keys, including Fn)|Make sure the touchpad is responsive to touch and gestures|Run a stress test (e.g. AIDA64) to check temperatures|Check all port connections (USB, HDMI, audio)|Make sure the battery is charging (the LED should be orange)-->

If everything works correctly, but the laptop has become make more noisethan before disassembly, the reasons may be as follows:

• 🌀 The cooler is installed unevenly (check the gaps between the radiator and the processor).
• 🔧 The cooler screws are overtightened (loosen them half a turn).
• 🌡️ Too much thermal paste (excess may get on the fan blades).

⚠️ Attention: If, after replacing the thermal paste, the processor temperature under load exceeds 90°C, most likely the heatsink is not pressed sufficiently to the chip. Try adding a 0.5mm thick copper pad between the heatsink and the graphics chip (if you have one).
