    Well nothing happens when you push the power button. The model #MA7 worked fine until one day went black and nothing since. We are a tech savoy family, also have freids who work in that area but laptops are different.I really would like to get the solution so I can have my computer back and yes it was 500.00 dollars

    i have a gateway mt3705 and its not getting any power? i tested the power cord and it works, the battery shows 75% power....but i cant turn it on and it doesnt show a charging light when plugged in. whatts wrong? send replys to

    I was using my gateway ma7 and it just cut out. Went totally dead! I checked the fuse in the power adapter and it works. I reckon its an internal power problem as the battery did have some charge in it, so it wouldn't have just completely died the way it did if it was the power adapter.

    any ideas?? I have read a few other posts mentioning the motherboard..?? Could that be the problem....I really need to get my laptop up n running again as I have tons of work on it and dont want to lose any of it.

    Thanks in advance.

    I have the Gateway MT3705 (Vista H.P./ out of warranty). It powers on (the power and charge lights both are blue) and on the touch pad there is the icon that looks like a cup (to me) that stays on for about 30 seconds, but the screen stays black and no sound. When I put a bootable disc in it spins and makes noise for a minute then just completely stops. Nothing else.

Hi flady_98,

You don't specify model, so what follows is fairly generic. If you can provide more details, perhaps I can too.

If it's booting (start-up chimes/sounds), then I'd suspect the display (either the back-light, or perhaps the inverter/controller circuit board). Backlights require (in my experience) replacement of the display, likely more than the value of the laptop if it was a refurb (~$500 and up in my exp.). Inverter boards are less spendy, but you have to get the right one, and get it installed (how tech-savvy are you?)

If it's not booting at all, (don't hear the hard drive spooling up, etc), then we start looking at power supply issues and go from there. But I really need more details.

If I can be of further assistance, let me know, and include as much detail as possible (you should be able to load digital pictures onto this space using the toolbar above).

If this solves the issue, please rate it accordingly.

Thanks in-advance for using,

Hello, zx4300 black screen, fan is working, led light works test another hard drive still will not work, very confused please help

I'm beginning to think that the gateway zx4300 all in one has a major defect problem with the motherboard. Mine is 8 months old and the screen went black on me a couple of times then totally went out. I took it back to best buy (still under warranty) they sent it to Kentucky (gateway) 3 weeks later got it back and it's starting to do it again. I'm not happy and am pretty ********** at this point. I use my computer for business and this has been a major inconvenience and money loser. I want to have gateway trade this for a different computer. 8 months old for this to happen is unacceptable.

My Gateway went black screen no lights what happened

I don't know exactly what's going on, but I'm going to give you some basic guidelines to help you troubleshoot this.

First of all, it may be of little use in this situation, but here is the basic component replacement manual: 8512061 - Component Replacement Manual . Keep this PDF handy for reference purposes. Other documentation for your model can be found on the Gateway site as well.
I suspect that this is due to one of two things: either video or power.
While I find it unlikely, you could have a bad video controller (built onto the mobo), a bad cable connector, or a bad FL inverter. The best online guide for fixing your own video problems is here:

One post on the same site refers to a similar Gateway model and implicates either the power jack or the mobo: See if the power jack (where you plug in your AC adapter) seems loose. If so, you could have a bad power jack connection, which would explain the off again/on again nature of all this, though typically you would eventually end up with a depleted battery.

This link illustrates a Toshiba model, but the principle is still the same:

I it IS your mobo and if you are comfortable doing it yourself you can probably find a replacement mobo online.

Good Luck!

I'm betting that you need a new "Inverter" board, especially if it's a Gateway 450ROG.
There is an inverter that Gateway used in several models that has a known defect.
Inverters are relatively inexpensive ,and easy to replace. You could ven do it yourself if you have a little skill at disassembly / re-assembly. Tell me the model number of your laptop and I can help you more
