Many laptop users may have experienced such issue, the laptop shuts down suddenly.
Yes, it is a common problem for laptop. Recently, I am tortured by this issue.I owned
my hp g62 july last year. It has been working for a long time. However since last week,
it will shut off automatically. I am a computer illiterate, so I need to seach this issue
on google and ask help from expert. From endeavors, I collect the following reasons
and solution for this common problem.
Possible Causes:
1) My hp g62 power adapter is malfunction.

3) My hp g62 is overheating.
Solutions:
1) For charger's malfunction. We may borrow a hp g6 charger from our friends or
purchase a new one from online store which is fast and cheap to check it out. If
another charger can't change the situation, that means the real issue is not lying in
your laptop power adapter.
2) For troubleshooting loose dc jack, you may try the following step:
If you have to wiggle your laptop ac adapter on a position to let it plugged in, it is
confirmed that your laptop power jack is loose or dead. Meanwhile you may fix it by
yourself on the basis of the following instructions article. The premise is that you are
good at tech. Otherwise you are required to take your laptop to a tech center for
examination.
3)Indications of laptop overheating problem:
1、The keyboard and the bottom of your laptop are very hot when the laptop is
working.
2、The CPU fans are working all the time at maximum rotation speed and
operate much louder than before.
3、The laptop suddenly shuts down by itself without warning. When it just

2. started, the laptop was shutting down after 1-2 hours and how it shuts down after
5-10 minutes of operation.
4、The laptop works fine when it runs idle, but shuts down as soon as you start
using any memory demanding applications (DVD player, image editing software,
video editing software, etc.).
And Possible Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned
air and just blow it inside the laptop through the openings on the bottom and on the
sides. It’s nice as a precaution measure, but it might not work if your laptop already
has a problem and the heatsink is completely clogged.
1、Open the laptop case, so you can access the CPU fan and the heatsink. In
some cases you can access the heatsink through the latch on the bottom of the
laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the
laptop case all the way down.
2、Carefully disconnect the fan cables on the system board and remove the fan.
If the fan makes unusual sound when it spins (grinding sound), I would recommend
to replace the fan.
3、Clean the fan and the heatsink with compressed air.
4、I would also recommend removing old thermal grease from the CPU and
applying new grease for better heat conductivity.
