How to kill a laptop (HP G6) and how to prevent this issue

How to kill a HP G6 Laptop The easy way to kill a HP laptop

We've just had a HP G6 laptop in that would not power up, show any lights or do anything at all - the owner said: “We shut the lid and put it down by the bed before we went to sleep, then in the morning it just wouldn't power up at all!”.

Our first thoughts were that the power jack or mains charger could of burnt out or become damaged in some way - only on further investigation did we find the below (on removing the heat sink and fan assembly):

Compacted dust build up Solid compacted dust blocking airflow through the cooling fins

Unfortunately it's too late for this laptop motherboard - it needs to be replaced, one has been ordered already.
A few simple rules will help prevent your laptop from over-heating and causing the same problem.

Preventing laptop over-heating problems

Prevention really is the best medicine here to avoid a costly repair job - 3 tips to prevent this problem follow:

  • 1. Try to operate your laptop in a low-dust environment - this includes making sure pet hair can not be easily drawn into the fans air vents
  • 2. We recommend that you blow the dust from your heat-sink through the side vent with a can of compressed air - this should ideally be done monthly
  • 3. If the laptop starts to feel hot to touch (on the under side) it's probably time you booked it in for a clean up session


In Summary

Heat kills laptops (and Computers/desktops) - if you budget for a laptop/PC clean up about once a year or every 18 months you can avoid having these problems nearly altogether - if you detect heat: get it checked out.
