Remove the SATA HDD, RAM meory module and WiFi mini PCI card More detailed information for this step you can found in this manual:   Acer Aspire E1-571 - HDD / RAM Memory / WiFi card Replacement .

RAM doesn't need to come out for mainboard removal, although it takes half a second to remove it.

The black antenna cable needs to be picked out of the groove so that it can pass through the hole of the chassis later for mainboard removal.

Remove the 2x screws and disconnect 5x flex cable connectors: 2x Loudspeakers cable connectors LCD Display cable connector
  • Remove the 2x screws and disconnect 5x flex cable connectors:

    • 2x Loudspeakers cable connectors

    • LCD Display cable connector

    • Microphone cable connector

    • USB board flex cable connector

  • Don't forget to remove the Card Reader Blanking Plate.

  • To take out the Motherboard, pick-up it first from the right side (near to the DVD drive connector).

At this point, the black antenna cable can be pulled through the hole in the mainboard. It is also held to the mainboard with tape on the left hand side (the grey path in the picture, from the hole in the mainboard up across the heatsink/radiator and over the top-left mainboard screw.

Clean the radiator by using soft brush. Clean the radiator by using soft brush.

An aircompressor or a can of compressed air from a hobby or electronics shop will blast the dust out of the fins more effectively. On models with a secondary graphics chip (chip would be in the blank spot at the top-left of the second picture), the heatpipe comes down and turns and then travels across the CPU next to the CPU heatpipe and then joins to a much larger radiator with longer fins and is much harder to clean.

What did you use to remove the old thermal paste? Did you use Arctic Silver ArctiClean?

Models with secondary graphics cards have two more screws to release the GPU heatsink. The heatpipe for the GPU and CPU are bonded together and go to a larger radiator.

Put a new thermal paste. Cover the entire surface of the CPU crystal. Install the Heat-sync system and screw the screws at a few steps. Install the Heat-sync system and screw the screws at a few steps.

Cleaning the factory paste off is usually easy due to it going brittle and no longer sticking well. I use a soft facial tissue to scrape the CPU and GPU clean and then apply Arctic Silver 5 paste to my finger tip and paint it onto the chip fairly evenly.

Steve Rand - Reply

Place the heatsink on the chip and give it a little jiggle around to spread the paste a tiny bit, locate all four screws and do them up very loosely, then tighten one finger-tight, then diagonally across, then back to the first side, then the last screw. Repeat again but doing them up until they stop. This evenly-tightened method will help the heatsink sit flush with the chip and help spread the heatpaste evenly.

Assemble the laptop and after switch-on it check is the fan working.
