Laptop freezes when moved or lifted

Problem description:

The laptop freezes when moved or lifted. When the laptop is on a table and not touched, it works fine. The laptop freezes only when moved.

Possible cause:

1. Poor connection between memory module and motherboard.
2. Faulty memory slot.
3. Faulty motherboard.

Possible troubleshooting steps and repair solution:

When the laptop freezes if moved or lifted it’s likely that the problem is somehow connected to the memory module/modules.

Maybe one of the memory modules is not making good contact with the memory slot, or the slot itself is faulty.

Here’s how you can troubleshoot the problem.
1. Try reconnecting memory modules and test if it fixes the problem.
2. Test the laptop with each memory module installed into each slot separately. Move or lift the laptop and see if you can find the failure pattern. If the laptop works fine with both modules installed into the slot A but freezes with both modules installed into the slot B, most likely the slot B is bad.
If one of the memory slots is bad, you’ll have to replace the whole motherboard or use it with only one memory modules installed into the good slot.

If reconnecting or moving memory modules from one slot to another doesn’t help and the laptop still freezes, most likely there is a problem with the motherboard. Apparently, there is a faulty solder joint somewhere on the motherboard. When you move or lift the laptop, you actually flex the motherboard and because of that it fails and freezes the system.
