I haven’t done many technical posts for some time but I have spent a great deal of time looking for a solution to using Wake on Lan (WOL) on an Acer laptop when the lid is closed. In my case it sits in an entertainment center and I have to pull it out and open the lid to wake it, but I want to be able to wake it up remotely with WOL.
I found posts that said to use a registry hack with the ‘LidAlwaysOpen’ command and the ACPI lid fix, neither of these did what I wanted, WOL would not work when the lid was closed. No power settings or bios changes fixed the problem.
I knew from searching that the sensor for the lid position on the Acer laptops is magnetic so after more than a year without a fix I got brave and started looking around inside the laptop, which incidentally is a 5552 but this should be the same for most Acers.
I gently, GENTLY pried the plastic back from the bottom of the screen, on the left side (when you are facing the screen) and found a small bubble of masking tape. I picked at the tape with a paper clip and uncovered a rectangular magnet, which I easily removed with a small pair of computer pliers.
Fixed, it works like a charm, the computer no longer knows when the lid is closed and WOL works like a charm. The screen snapped together again easily, it is a super easy fix.
- Shut down the computer and remove the battery just to be safe!
- Pry the plastic away from the bottom left of the screen
- Locate the magnet (may be covered with tape) just to the right of the hinge
- If you are unsure it is the magnet, use a paperclip to see if it sticks, if it does, well that there is a magnet my friend.
- Remove the magnet, being careful not to scratch the screen or plastic bezel.
- Snap the bezel back in place and you are good to go.
If you are careful and keep the magnet you will be able to reverse this very easily.
