Windows 7: HP Laptop keeps turning off randomly

XP Pro (x86) | 7 HP (x86) & (x64) | 7 Pro (x64)


I have a Toshiba Laptop purchased in 2012. For about a year it was randomly shutting down.
- I had a very old Acer with Linux on it and the fan firmware in the machine was not recognized by the Linux OS
- the Acer/Linux lasted about 20 miniutes then would shut down. Let it cool for 15 minutes and it would start again for a too short time.
Assuming my Toshiba was overheating I propped the back edge up on a length of wood. The problem was the "strip of wood hindered the air flow, the heat from under the laptop was quiet obvious.
Another symptom of over heating is weird behavior of open windows, it starts to look like a collage/jig-saw of bits of open windows.

No amount of extra fans, over heating detectors etc ... will remedy a dirty heat dissipation problem.
The ONLY solution is to clean the inside of the PC. Fan and Heat sink

Search YouTube for how to clean your HP laptop, there is no easy way to clean,
some YTs advocate using all sorts of bazaar ways to blow air into the out vent or at the heat sink, with a drinking straw and a piece of dry bread in your mouth. Definitely a no-no.

By using DuckDuckGo search engine you can use a shortcut to search for only YouTube videos.
DDG: DuckDuckGo
Search: !yt xxxxxxxxx
- where xxxxxxxx is what you are looking for
- the !yt trick only works with DDG search engine

It took me a few days to find a half decent video on how to clean my Toshiba.
- there are a lot of crappy videos in YT land, but there are some gems
Britec is a very useful YT channel, all his videos a first class. But keep searching and list the videos that look promising on Notepad or any TEXT editor (or Word pad, or even Word), eventually it will fall into place.

There are no quick fixes to an overheating PC. Like a teenages bedroom, when you cannot close (or open) the door it is time to CLEAN !

Don't rush it when you do get into pulling the laptop apart. Gently does it. Clean means clean, not just rearrange the dust and crud, Domestic vacuum cleaners are way to savage and can cause damage. Compressed air (in a can) is safest, because it is dry.

My Toshiba, was so old the bottom case fell to pieces (because the previous owner had left out some serious screws) plus I broke the keyboard connection. Toshiba's are a dog to clean. A new case cost me $23 and I have a "rescued" laptop

My Lenovo laptop is a dream to clean, just take off the back plate and there is the fan and heat sink.

Here is a bad example of how not to clean a HP laptop how to clean the hp laptop fans - YouTube
- blowing all the crud back into the machine and around the heat sink
This good YouTube How to Fix an Overheating Laptop - Step by Step Fan Cleaning - HP Pavilion dv6500 is one video that got me started.

Cleaning the heat sink AND new thermal paste, is recommended with any machine, especially considering the age of you HP Laptop.

In 2 months time I will be 72 ... if I can do it anybody can. I have now cleaned (rescued) 3 laptops.

Good luck ... ::)

Since laptops are notoriously easy to get dirty and hard to clean, I caution all my laptop users/customers to never set their laptop on a bed or rug or any fibrous surface. Only set a laptop on a clean, hard, surface, to avoid it sucking dust and dirt up into the cpu/gpu heatsink.

I've successfully blown the dirt out of the heatsink using compressed air, while preventing the little cooling fan from turning, by inserting a thin rod into the fan to prevent the blades from turning. Over speeding the fan can cause damage to the blades. It's kind of a touchy process, but if done right, it can greatly lengthen the life of a laptop.

Cheers Mates!
