if your laptop has the hp quickweb function then try booting it through that i think that it is the f5 button to launch it when your computer is shut down. let me know if this works. :)
With a laptop, much of the chip & motherboard design is bespoke (to fit it into the space and power constrains of a laptop) and does no lend it self to upgrades.
The powersuply. In a laptop it might be the powersupply or the battery (when unplugged).
Send it to the manufacturer and wait
Unplug the powercord and run on battery. I have an external that flickers with the cord in so i uplug it for awhile and it fixes it. Ive heard a two prong power cord fixes the problem.
Hardware components of a laptop are: Motherboard CPU RAM Expansion cards Power supply Optical disc drive Hard disk drive Keyboard
Your motherboard is attached to a power supply inside your system if it is desktop, and a mobile power supply if it is a laptop. The motherboard is built so it fits right into your computer and plugs in. Once it is plugged into that power supply in your computer, then everything else you put in it follows with it. That includes your GPU (graphics card), your CPU (processor), memory, hard drive, the fans for the CPU and GPU, and other things. There are alot of things that a motherboard attaches to.
It is most likely that there is a problem with your power. If your machine is plugged into mains power, check that the plug socket has power, check that your power adapter is okay, check that the power cable into your laptop is okay.
A motherboard is compared to a power strip or a mother.
To be specific, I don't mean the power adapter , but the part it connects to. The part you plug the charger into. I need to know the name of it so i can replace it.
There are no differences between the power connector of an AT motherboard versus that of a BabyAT motherboard.
Every laptop has a different power rating.
You should not bother to check any power supply in the motherboard. You need to take the motherboard to service centre if faulty.
