Could be the power supply, the power button, the connector on the board, or the motherboard. Try taking out the battery and see what's happen.

Is there an internal fuse for the incoming power for a gateway laptop computer


No... there aren't usually fuses for laptops. You may have a bad power cord... it's a transformer that converts 100-250VAC to 12VDC usually. Get a new one, but before you do, borrow a friend's with the same brand of computer to see if that's your problem or you can have them charge up your battery pack and see it your laptop powers up normally. If it doesn't check my pther post on a gateway laptop that fails to boot up normally. Could be something else!

Is there a power input fuse on a Toshiba Satellite C655D?


no, there is no internal fuse, unfortunately- because this sounds like a dead motherboard. the aftermarket power supply could have been over-volting, or delivering unsteady power- burning the motherboard.

OR the old power supply shorted, and blew the motherboard's power circuitry, and you were just running off battery power when you first got the replacement.

please keep in mind that, at times, the physical power input jack on laptops can also break, or come loose from the motherboard.

The CMOS batter could have been solder onto the motherboard. In most laptops, the batteries are not removable. They only power the BIOS settings (time, date, computer configuration, etc.) They do not power the LCD.

Sounds like you have something else wrong.


I don't get paid for advice so if this answers your problem, I would appreciate 4 thumbs.

Hello. I can help you. As you indicate the problem could be the computer itself, the battery, the charging system, or the outlet you are using to plug into.

That said, begin by shutting the computer down and removing the battery for two minutes. That will reset some parameters and may solve your problem.

While you are waiting the two minutes, plug something else into that outlet, say a lamp just to be sure there is power there. If there is no power then go to your electrical panel and check the fuse or circuit breaker, which ever you have.

Now plug the computer in, still leaving the battery out and turn it on. if it operates that way unplug it again and reinstall the battery.

If the computer works on direct electricity but not on battery you could consider buying a new battery.

Regards, Joe.

I accidently connected a 28volt charger to my evo


if the battery charger powers the computer, then i would imagine the motherboard is fine...

there should be some kind of fuse insode the battery to prevent things like this from causing them to explode.

Gateway solo mt6840 power input is not working


I had the same exact problem, the computer techs I talked to all said it was either the DC Jack or the Motherboard. They will need to open your computer to check this out and they usually charge to do this. I had the DC Jack replaced and still had the same problem so their next suggestion was to get a new Motherboard which can set you back quite a bit. Try to find a Computer repair shop who will give you an estimate at a minimum to no charge, also ask if they are able to fix the Motherboard without totally replacing it if this is the problem. This will most likely be at half the cost of a new Motherboard. My computer was fixed for a total of $220, that was $150 for a Motherboard repair and about $50 for the DC Jack repair. The only drawback was the company ended up damaging the body of my computer and won't own up to it. Whatever you do, don't send it to Pell Technology and get it done in the near vicinity. Also take pictures of your computer before you leave it with any computer repair shop.

Compaq Armada E500 shut off and won't restart.


The notebook does have an overvoltage and overcurrent protection inside the computer itself. The problem is definitely in your low voltage power supply section of your notebook. Since you do have a multimeter and know how to use it. Take your notebook apart so that you can see the board that your power adapter actually plugs into. Your notebook may just have a normal fuse that you can see is blown since they do make that little popping sound and do not leave any discernible smell of an electronic component that burned or blew up so to speak. That you cannot smell anything like that is good. If you do not see a regular fuse, there are what are called bell fuses that look like miniature glass diodes or resistors but are actually inline fuses. Your entire notebook should not have more than two or three. Sometimes they are made of ceramic, but that is only used for high amperage uses like on plasma screens and such. If the fuse is visible and checks blown try another one and watch it as you power the computer up. If it blows again check your on/off switch without power to your computer to be sure it is not shorted out. Then trace your voltages into your computer with power on and see where you do not get any voltage down the line. It is pretty straightforward in tracing the voltage from your adapter into the computer. Remember though that the intial voltage from the adapter is broken down into smaller voltages for the logic circuits. It is apparent you are not getting any voltage past right inside your computer's power supply and voltage regulator section. You in my opinion have an open circuit instead of a short right now. If you find fuse and it blows again then you have to find the shorted component. Let me know and I will be glad to help further. Good luck.

Does it come on when you are using your power cord? if so, then my assumption is that your battery is dead or something is wrong with it if it is a new battery. If your battery/computer is new and still under warranty, you can petition your computer manufacturer, under the warranty, to replace the battery. If your computer does not come on even when plugged up, then there is probably something wrong with the power source on the computer, and it needs to be repaired. If your computer is still under its warranty, then contact your computer manufacturer and explain to them what is going on. They will assist you on where to take it, if locally, and/or where to send it. They should provide all shipping boxes/paperwork.
