Laptop will not switch on

I have a Gateway mt6452. It's been a good machine and gone with me around the world. When I press the "on" button, it turns blue for a second, and then nothing. In the past few months, I would press the button 674238923 times (just kidding), and one random time it would start-up. Now, the machine won't come on at all. Any ideas? Bad switch?

    Rogervista, the machine will not power-up at all. I'm using Vista Home (when it finally boots).

  • episcopaul Jan 17, 2009

    Honest1abe, I've done all you've recommended. Nothing. The only thing that consistently happens is: If a/c or battery is connected, I get a momentary lighting of the blue button that I'm pushing to attempt start.



    Could it be that switch that's gone wrong?

Shut down the system, disconnect every thing you can possibly disconnect and remove the battery.

Press and hold the power button for 15 seconds. Reconnect A/C power and try to boot up.

If no change, remove the CD/DVD drive and if you feel comfortable, the hard drive. Reconnect power and try to turn on again.

If you still get nothing, check for any loose screws on the bottom of the case and snug them (DO NOT OVER TIGHTEN). Just finger tight so the screw is not turning loosely. Remove and reseat the RAM. If you get no power, remove the RAM and reconnect power to see if you get beeps from the system.

Let me know if you need to go further than this.

    It indeed may be that on off switch or the plastic piece that connects between the button and the actual microswitch on the mother board.

    Search your local area for laptop shops offering free diagnostics. If it is the plastic piece, should not cost much to fix.

    If the switch on the MB is failing or is loose in the connection to the mother board, that is typically a MB replacement. You would then want to evaluate the cost advantage of repair versus replacement.

The power button in my Gateway laptop MT6451 got pushed it can't be accessed from the top. How can it be accessed from the button?


Quite easily Sergio

The plastic Power On button you see, presses against a carbon button Power On switch, below it.

I suggest removing the Switch Cover, and then you can access the Power On switch's carbon button, and press it down to turn the laptop on.

You can also, then see about repairing the Power On button assembly, or replace the Switch Cover.

1) Remove ALL power. Remove the AC adapter {Charger}, and Battery.

2) Laptop closed, laid on it's top; Bottom side up.
Turn it so you are looking down in the Battery Compartment, where the Battery was......

Down in the Battery Compartment are 4 Philips head screws to remove. You need the smaller No.1 Philips screwdriver, or the equivalent Jewelers screwdriver.

Here is the Base Enclosure, (Bottom Cover), not installed on the laptop,

http://www.ebay.com/itm/39MA7BATA10-Gateway-MA3-MT6451-Bottom-Case-Cover-39MA7BATA10-Genuine-/321101430142?pt=LH_DefaultDomain_0&hash=item4ac322fd7e

There are 4 views. The page automatically opens, with a Bottom view, and the Battery Compartment at the top.

SET, your mouse cursor in the middle of the photo. This allows the Zoom In feature.
Go to the top where the Battery Compartment is, and view the 4 holes going along the Top.

This shows you where the 4 screws to be removed are.

Same design, different Gateway notebook,

http://www.insidemylaptop.com/remove-keyboard-from-gateway-mt6704-model-ma7/

Go to the third photo down. Has two screws circled in Red.
I just want you to look at the Battery Compartment. (Not the red circled screws)

Look under the whitish - www.InsideMyLaptop.com -
You can see the first two screws pretty visibly. Almost make out the 3rd one, no to the 4th screw.

Once these 4 screws are removed, turn the laptop over.
Open the laptop.

Now you are going to remove the Switch Cover.

In the above link scroll down to the 5th photo, and 6th photo.

This video also shows you,

http://www.youtube.com/watch?v=KjOVOLOW1Hc

From 0:45 to 0:47
Please use care when removing, it is plastic.
The video has been sped up.

This is a look at the Switch Cover removed,

Gateway NV78 laptop turned off and won't reboot.


So reformat a computer that can't access the hard drive, interesting trick. I believe the OP said the machine hangs in limbo with Power Lights on, I assumed the Lights are on, but no one is home, sort of like some of these solutions. Why am I not paid millions of dollars for being the smartest man alive?

Gateway nv52 won't turn on


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...

My gateway MT6728 laptop is not working at all, when I turn it on the screen kepts off, can't hear nothing (only a cooling fan) and basicaly can't do anything


The cooling fan spinning is a good sign. Your laptop might still be functional.

First, try taking the battery out. Then press the power button 10 times and on the 10th time hold it down for 10 seconds. This will purge any remaining power in the laptop.

Put the battery back in its place and attempt to turn the laptop on. Observe the behavior.

If the problem still exists, your video card might be malfunctioning or the inverter (monitor's power source) might have gone bad.

Try hooking up the laptop to an external monitor, if an image is displayed, it's most likely the inverter.

You can take the laptop to a repair shop to get it fixed.

My Gateway laptop shuts off after five minutes. I


Hi there.
There is probably dust trapped in the air vents and around the CPU fan, the best way to clear it is to turn the machine off, get a can of compressed air and give short blast through the air vents.
The CPU fan is usually located under the laptop and give a couple of blasts through that too.
Once your happy that all the dust is removed you can turn the laptop on again and it should stay on for much longer.
The cooling pad won't make any difference if the issue is dust.

Good luck and thanks for choosing FixYa!!
