Unfortunately, you can't solve this problem. What I have learned as the tech working on a customers gateway mt6451 is that Gateway dropped the ball when they bought a cheap (they spent 5 cents instead of 20 cents) motherboard component that allows the adapter to charge battery and run the notebook without the battery installed, the component seems to have a 1 year if that life. I am surprised they haven't been sued or forced to extend the warranty (like HP had to with their dv8000 series notebooks) althought they would have to replace the motherboard with one that has an improved component on it. How do you sue a company or force them to extend the warranty for a replacement that is made with a better component?

Anyone have troubleshooting info?


Im not an expert by any stretch i have a vizio with the same issue and I have also replaced the powersupply / dc inverter board. I suspect we both need new mainboards. A site named shopjimmy offers many replacement parts at good rates. I am in the process or replacing the Tcon and LED driver boards now (they are much cheaper than the main) if either of those corrects the issue ill post a comment. FYI My problem on the Vizio TV was corrected by replacing the main-board after all.

Charges but lights flicker when trying to turn on then lights turn off and nothing happens.just bought new charging cord oem.


Not all oem's are created equal, this sounds like a power supply issue. I would be tempted to try another power supply, first remove the main battery and press power, if it comes on the rechargeable battery is bad, replacement only option.

I think my HP Pav powersupply is dead. When I plug it in and try to turn it on, nothing happens to the HD and computer except a green light flashes on the back of the power supply. It is a Bestec...


all atx powersupplies are generic-it dous not really matter what computer it comes from unless its a high end pc requiring loads of power-if your machine is intel you may need a supply with an extra twelve volt lead(two yellow and two black leads in a little block)-but for that pc i would just harvest a powerpack out of a dead machine

Flashing orange light on front of my dell 5150 desktop, will not turn on, even after unplugging for one hour. when plugged back in, flashes orange, no fan, no power. JK


So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?

First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button.
Try to boot the pc.

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker, put the powersupply in a different pc, or try a different powersupply in the problem computer.

Could be bad ram, motherboard, cpu, powersupply, videocard.

Emachine T3624 desktop PC won't turn on?


I can guarantee 100% you have a bad motherboard. I have seen this exact problem with hundreds of E-machine PC's (especially your particular model).

What happend is the power supply went bad and took the motherboard with it, e-machines use very cheap OEM powersupplys that do not have any fault protection to protect the motherboard from damage if the power supply gets a surge or other damage.

You should not waste your money repairing the hardware in this PC, i would buy a new PC and transfer the data over.

Simpletech 320gig hard drive crashed?


I like ones like you who already understand that a lightening power surge can really kill the computers will to live lol

1. always put the computer on a surge protection strip or even better a UPS backup device to protect it from surges , and in the case of brownout the UPS backup would take care of that circumstance
or at least some kind of VR , voltage regulator ... not that computer powersupplies do not protect the PC , the PC powersupplies of today to have some built in protections , but ooops there went your power supply anyway if you know what I mean.

2. if you suspect the power supply is the culprit , you can test by using another power supply
which is a good investment because if it was the power supply you just got yourself a nice new one
and even if it's not the power supply , you still have a nice new one in your hand

a power supply in the hand is worth two in the bush :-> lol

and if it's the motherboards fault , at least you'll already have your nice new power supply for that new motherboard you get.

a good strong power supply is a good investment no matter how you slice it.

I always keep any spare power supplies I get , because you can use them while your dead power supply is being RMA-ed or sent back. ,, that time gap is not fun lol

Beeping Upon Bootup


dependent on how many beeps you hear is dependent on what might be the problem. A fuller explanation from pushing the power button to nothing happening would be more than helpful. Beeps in a Poweredge can mean motherboard, memory or as you said power supply problems.

Red light flashing on power button


Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.
