My Gateway NV5378u laptop does not turn on. I have tried swapping the battery from another computer (NV5378u also) and running it on just ac. When the power cable is connected to the computer, the cord loses power (the green light turns off and when connecting to the other computer, must be unplugged and plugged back in before it has power)

SOURCE: Gateway 7330GZ laptop. Good battery, good Ac Cable will not turn on?

The system board on the laptop needs replacement.


Hope this helps :)

Could be your connection inside the laptop itself.

I also had this problem. I turned it off and it would not turn on. I found the solution. First, extend the laptop screen as far back as it will go. Don't just stop the screen at a ninety degree angle. My laptop screen pulls back to about 135 degrees. Now press the power button. It should start up.

Why do I think this works? Well...I used to own an older model thinkpad that had a short "male" connector on the screen, that when the screen was folded down would enter into a "female" connector on the base of the unit and trigger sleep mode on the unit. This is how the system could automatically hibernate when the screen was closed. The little male connector broke off, and I couldn't get the system to wake up, because the connection to tell the laptop that I had the screen up or down no longer worked. I couldn't even power it up. I had to take an ink pen and push the connector through the female end to indicate to the motherboard that I'd opened the screen before it would even turn on.

It appears that the same type of mechanism is built into the long BAR under the screen of the NV52 and somehow it can't determine when the screen is open or closed. If it detects that the screen has not been opened, it won't power up. This safeguard prevents the laptop from being turned on mistakenly while closed up in your laptop bag. Extending the screen back resets the mechanism and it should turn on. Sorry for the long explanation...

Seems to be a problem of not enough power.

First check the voltage output of the charger(adapter) and match it with its specs.


Also try to reset the hardware using the following steps:

1 Disconnect battery and the charger
2 Let it sit for 1-2 minutes.
3 Press and hold down the power button for 30 seconds.
4 Reconnect battery and charger and try to start by pressing the power button.

This is a factory reset protocol.
