Laptop Not Powering On Issues & Resolutions:
There are quite a few different reasons why a laptop can have issues powering on. The most
common would be a faulty DC Jack. Though other things like a faulty GPU, or incorrectly seated
RAM, or a blown motherboard component, a bad battery, a damaged hard drive, a short in the ac
adapter, or even liquid damage can as well… So you see; it is not only the power area that can fail
rendering the laptop unable to power on and stay powered on it can be a variety of different issues,
and it will be up to you to do process of elimination testing to rule out all other possible problems
and pinpoint the exact component causing the issue.

I will go ahead and give you a few scenarios and then resolve the issues for you by showing
you how to do process of elimination testing.
1) Let’s Say… The laptop in front of you will power on when the power button/switch is pushed,
it will even splash the BIOS screen (the screen showing the Laptops manufacturers logo), then shuts
itself down.
Okay, Now for the process of elimination testing to determine the issue.
You will want to first check all the easiest things that you can, the easiest parts to access get looked at
first.S tart by removing the battery. Plug the AC Adapter in and try powering on… If the same,
continue on…
Next, remove the RAM cover on the underside of the laptop (some RAM slots are also situated under
the keyboard on the top side of the Motherboard; you will determine the location and reseat both
sticks. Then attempt to power back on after reseating the RAM. Reseating the RAM means that you
remove both RAM sticks and place them back into the DIMM slots again to ensure they are in straight
and not at an angle or slightly ajar.
If you are still getting the same failure when powering on, then pull out both sticks of RAM again
and just use one stick, placing it in DIMM 1 first, then checking Power, then trying just DIMM 2, then
trying to power on, then taking the 2nd stick of RAM and doing the same thing… trying DIMM1 then
DIMM2… That will either rule out the RAM as being the issue if nothing changes, or it will correct
the issue, which would also tell you that you have a faulty DIMM slot if the laptop Runs and Powers
on good with 1 missing RAM stick…
N ext you can move on to the Hard Drive by simply removing it. You want to remove/unplug it
from the port and set it aside, then try powering up the laptop because if the hard drive had any issues
with it that were stopping the laptop from powering on, removing the drive should bypass the issue
and allow the laptop to turn on. Liquid damage to the hard drive is a common reason this can
happen… Liquid damage to the internal components can cause power redirection where the contact
pads join and when this occurs, it will tell the motherboard to shut down to prevent further damage. If
the laptop is still not powering on, continue with process of elimination testing…
