How to fix the HP Laptop are shutting down by itself

hi.Fan Always Runs Or Laptop Overheats And Shuts Itself Off
Warning! Before Disassembling Laptop always unplug power and remove the battery.
Laptops that shut down without warning are often experiencing overheating issues. Overheating may be a symptom of age, of clogged ventilation or impending failure, but it can also result from simply using the laptop in a bad location. Before you try to take the laptop apart to look for problems, it pays to patiently troubleshoot the symptoms and see if an easy fix is possible. I wrote The Laptop Repair Workbook to teach basic laptop technology and troubleshooting to regular people and techs in training. The overheating flowchart below is one of twelve flowcharts in the book.

its either a bad power chord or the power supply or fan

Open Control Panel, Power, power settings, change power settings to high performance, Disable Hibernation, sleep. When your laptop is not in use shut it down and unplug. It will last longer and a boot everyday will reset the laptop.

its similar to the problem that with the laptop that get warm and shut down, the chip inside get warm and then it shuts down
its not worth to fix this problem

Clean the laptop battery connector point.
This will fix the problem.

Sounds like a failing HDD and/or overheating.

Hi..

If the laptop shutdown maybe it cause overheating.
Laptop shuts down? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed. Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

Good luck !!!

installing an auto update fixed this problem

Laptops are designed (by software) to shut themselves off as a protection measure. The most common problem is high temperatures. Do you hear your fan racing while you are using it? Do you sit your laptop on soft surfaces (like the bed or carpet floor) while using it? Do you smoke around your laptop while using it? These are common things that cause high temperatures on your laptop and will cause it to shut down. May not be your case but just a though. I would take it somewhere or open it up yourself(if you are pass your warranty time ONLY) and clean out the dusk with some air.

Hope this helps!
