HP Pavilion DV4 Laptop
My computer is not reliable & I think it's due to a power problem.
It used to destroy inverters when I lived in a van. The fan is always on, and it does get hotter than other computers. When I first had it it sometimes had problems charging the battery, and used to turn itself on sometimes.
I set the computer to shut down with 15% battery because it can simply cut out with the default settings. Unfortunately windows update has a habit of returning the power settings to default, with the result that sometimes the computer turns off suddenly due to lack of battery.
This results in problems in the configuration of the OS.
I thought the poor running was due to virus (which was a factor too), and I have disinfected twice, with help from geekstogo, and formatted three times
How do I repair the operating system (other than using system restore)?
How do I safeguard my power settings?
Is there a hardware solution?
