Gateway laptop computers don't start

I now have 3 gateway MT3422 laptops that all will not start - leds blink, dvd drive spins, cpu fan runs, No display laptop or external VGA batteries ok hold charge battery lights work OK. Need schematics to troubleshoot or at least parts placement diagram. This must be a common problem with gateway - any ideas?

    These are laptops - there is no clicking that I can here - the DVD drive does run - I have tried restore disks with no progress. I took one apart and cleaned up heatsink and redid with artic silver. I think it is a common Gateway problem an need help and schematics to troubleshoot. I am a EE and have lots of computer experience but cannot tell where or what is happening here.

  • john cleland Apr 25, 2010

    Sorry forgot to include, I bought 2 new mem sticks and tried them - did not help on any of the 3 laptops.
    One of the nvidia graphics chips shares the CPU hat sink so I used artic silver on that also.

    Do you mean I should unhook the LCD signal cable that goes from the MB to the LCD display and then try an external display through the VGA connector?

  • john cleland Apr 25, 2010

    Tried that did not work still no display or sign of BIOS.

  • john cleland Apr 25, 2010

    Thanks - I will try that in a few - have to disassemble some stuff to gt to the LCD connector. Later

  • john cleland Apr 25, 2010

    No Beeps from internal speakers don't have external speakers available right now.

  • john cleland Apr 25, 2010

    Unhooked the lcd cable and tried external VGA no luck nothing on external monitor.

Hi,
Even i had the same issue. This is a common problem not only for gateway but for other models also. Mostly this problem occurs due to overheating caused by using the laptops without proper bottom ventilation, like when up keep it above bed, pillow or so. Overheating usually blows up the graphics card, by which normally we have to replace the motherboard. I hope the laptops you've mentioned is not brand new. They never happen in them.
If the laptop is under warranty get the motherboard replaced. Else i would recommend you to approach a technician for the part replacement, if you are not well aware of the hardware part.
Gateway Manual to disassemble if you are an expert.
Thanx :)

A. Shut down the laptop and disconnect it from power cord. B. Remove battery after turn it over. C. Hold down the power button for 30 seconds. D Connect the power cord and try to turn it on. E. Now, at the start up try F8 and choose safe mode with networking. F. Else, at the startup press F2(Delete or F1) to go to BIOS and set BIOS to default settings. Hit F10, ESC once and choose Save and Exit and hit enter. G. If all of this does not work, you can try to reset your computer to factory setting by inserting the gateway recovery disks. Note: This process would delete all of the data of the computer. H.If this all also does not work, please try to reinstall the operating system. I.If this does not work, you can visit http://support.gateway.com.

Sometimes this problem occurs on gateways, due to the power converter for the LCD display. Since there is connected the LCD the signal isn't going at the external monitor. I suggest you open the case and unplug the internal vga cable in order to check the external monitor, and try to find power converter for the LCD as a replacement (maybe you should try change over between the 3 pieces) In case of a problem or clarification, don't hesitate to post me a reply.

    Exactly, I mean to unhook the internal cable for lcd display and use the laptop's connection for external monitor. This is because as the LCD is connected gets priority 1st class.

    In case of a problem or clarification, don't hesitate to post me a reply.

    Faulty memory or CPU could be the problem too. As I can see you already changed the memory modules with no luck. What about beeps during the boot up?

    In case of a problem or clarification, don't hesitate to post me a reply.

If either lcd ner external vga do not light up...and you hear the windows logging sound...it means that the video card is out ..and you have to open it ..and see whats going on ..it is either a loose plug or wire or is dead for good..and need replacement ...
another issue if it sounds like a loop booting ..is the ram memory (in this case it do not boot to windows at all and you do not hear the sound..) and it makes a click like sound each time it boots ( a few seconds apart )
In this case remove the power and battery ...get the ram memory out and place it back ...start it again and see what happens..
also try to open it up ..remove the keyboard ..and remove the bios battery for a few seconds..it may have a odd setting that disabled the video card or so ...and this will default it ..
if non of this work ...it is the video card for sure ..but ...try first to replace the ram memory from one that works ...cause if the ram memory is out ...it behaves like this too..cause the ram memory is the first thing a computer sees..
meanwhile I will look for a scheme or something ..but I dont think you need one ..cause things are simple ...better a video to see how you have to open it ..inside they are
pretty compact and on modules...not too many wires so ..you can make anything wrong..
and for Ram memory you do not need to open it ..but just remove the back lid..

    I still suggest to change the ram memory ..if there isnt any sign that it actually boots all the way ...I did had some problems like that when the ram memory was dead ..and it behaved just like that ...with nothing at all displayed..

  • Catalin Turcu
    Catalin Turcu Apr 25, 2010

    hmm after I sow what you posted and the other comments I got to think that you are right and it is a factory issue with the motherboard ...From what I see you have tried about all but changing the videocard...but like I said if it was that it should had sound...on boot..

How to repair start-up on my computer


How long is shortly? If it runs and brings up the Windows Desktop and you are allowed to work for 10 minutes or longer then it shuts down, most likely the laptop is overheating. One way to tell if it is overheating is to immediately try to turn it back on after it shuts off. If it will not boot back up, it's overheating. If you let it sit and cool off for a while, then try to boot it back up and it does it successfully, it's overheating.Causes of Overheating:1) Dust all inside the computer. Fans clogged with dust, dust around the vents.2) Fan not working 3) The Thermal Past around the CPU has dried up or is too thin the keep the unit cool.When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Gateway MT 3422 problem


There has been a lot of problems/ complaints about this particular product. That is why I always recommend HP notebooks.

You can take it to a service centre where they deal in Gateway products but I bet you might need to replace your motherboard.

Good luck.

Gateway boot problem


This mostly happens when your motherboard is bad or one of the memory modules is bad.

The led light comming on indicates your power pack is ok but a component is failing to start especially when the laptop stops at the first screen stage where the manufacturer names appears.

The steps needed to solve this kind of problem would require technical skills and physical inspection.

If you still have a waranty period then seek a free service repair from an authorized or certified gateway service centre at the nearest centre closest to you.

If your warranty has expired, i still advise taking your Laptop to the closest Gateway service centre.

Gateway Laptop overheated and stopped working.


Usually when the laptop overheats the CPU shuts down, and after it cools down you may be able to power it up again, unless the CPU has failed.
If you are able to get the laptop working, get the fan replaced, if it laptop doesn't boot up then there is a serious problem (most likely a costly one).
