laptop suddenly shuts down by itself without any warning. Sometimes it
works fine for hours, sometimes it shuts down in 10-15 minutes.”
This complaint we hear from our customers over and over again. About
15-20% of all Toshiba laptops we get for repair, suffer from an
overheating problem. Yep, OVERHEATING!
This is one of the
most common problems with Toshiba laptops we deal with.
laptop overheating problem:
- The keyboard and the
bottom of your laptop are very hot when the laptop is working.
- The CPU fans are
working all the time at maximum rotation speed and operate much
louder than before.
- The laptop suddenly
shuts down by itself without warning. When it just started, the laptop
was shutting down after 1-2 hours and how it shuts down after 5-10
minutes of operation.
- 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.).
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
- 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 you have to open the laptop case all the way
- 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.
- Clean the fan and the
heatsink with compressed air.
- I would also
recommend removing old thermal grease from the CPU and applying new
grease for better heat conductivity.
