How to disassemble Lenovo ThinkPad T570 and P51s laptops.

In this guide I explain how to disassemble a Lenovo ThinkPad T570 or ThinkPad P51s laptop. Both models are almost identical. The guide will work for machine types 20JW, 20JX, 20H9, 20HA.

For your convenience, at the end of this guide I will link to the official Lenovo hardware maintenance manual which explains how to properly maintain or troubleshoot the computer in a case of hardware failure.

Some of the Lenovo ThinkPad T570 and P51s laptop design features:
– It’s very easy to remove and replace the keyboard.
– You can have two batteries installed. One mounted outside and another built-in.
– This machines will support either a 2.5″ hard drive or a PCIe NVMe M.2 solid state drive.
– There are two memory slots available for RAM upgrade.

Removing the keyboard

STEP 1.
Unlock and pull out the removable battery. Loosen three captive screws securing the keyboard on the bottom of the laptop.

STEP 2.
Shift the keyboard towards the display. The top side of the keyboard will move under the bezel. It’s possible you will have to apply some reasonable force to make it moving. I had some trouble with that. Eventually I was able to move the keyboard after I used both hands and shifted it in a quick motion.

Shift the keyboard towards the display.

You know you did it properly when you see a gap between the lower side of the keyboard and the palmrest. Also take a look at the top row of keys, they are almost touching the bezel

Both connectors must be unlocked before removing the cable.
Lift up the locking tab (red arrow) to unlock the connector. After that lift up the cable and pull it out (yellow arrow).

Unlock both connectors and remove the cables.

STEP 5.
Now you can remove the keyboard completely.
If you need to find a replacement keyboard you can search by the FRU part number printed on the original part.
Lenovo ThinkPad T570 and P51s keyboard part number (US model) is 01EN928.

Now you can remove the keyboard completely.

Removing the built-in battery

The built-in battery is removable but it’s mounted inside the case. It’s necessary to remove to bottom cover in order to access the battery.

STEP 6.
Loosen for captive screws securing the base cover.

STEP 12.
Lift up the right side of the 2.5″ hard drive bracket. There is a small latch securing the bracket on the right side. Pull the black tab to the left to unlock the latch and remove the bracket.

This laptop supports two hard drive interfaces – SATA and M.2 PCIe.

Lift up the right side of the 2.5" hard drive bracket.

STEP 13.
In my laptop I had a 256GB PCIe NVMe M.2 drive installed. It’s connected to the motherboard through a M.2 SSD adapter.

Remove two screws from the SSD heatsink and remove it.

If you have a regular 2.5″ hard drive installed and would like to upgrade it to a PCIe NVMe M.2 solid state drive, you will need to buy a M.2 SSD bracket with adapter (FRU part number 01AY476) and an SSD cable (FRU part number 01ER035).

You can upgrade regular 2.5" hard drive to a PCIe NVMe M.2 solid state drive.

STEP 14.
Remove the memory module. This particular laptop came with only one RAM module installed but the motherboard has two slots. You can easily upgrade the memory. ThinkPad T570 and P51s supports up to 32GB RAM DDR4-2666 SODIMM (2x16GB) RAM.

Remove the memory module.

STEP 15.
Disconnect two antenna cables from the wireless card.

Removing the display panel

In the next few steps I show how to remove the display panel. It is not necessary to remove the display in order to remove the motherboard, it’s just they way I’m doing it.

– Trackpad cable (pink).

I will leave the CMOS battery connected to the motherboard to preserve the BIOS settings.

Remove two screw securing the motherboard and disconnect all cables.

I will leave the cooling module (heatsink and fan) connected to the motherboard but it can be easily removed. Simply loosen four captive screws and disconnect the cable. After that the cooling module can be separated from the processor. The heatsink assembly FRU part number: 01AY473.

I will leave the cooling module (heatsink and fan) connected to the motherboard but it can be easily removed.

STEP 25.
Carefully separate the motherboard from the top case and remove it. As you see, I left the heatsink assembly connected.
