Laptop won't turn on, blinking blue light

I am very concerned with this problem. I was using my computer normally, I had it plugged in with AC power. But then I noticed it was running out of battery. That seemed ridiculuous at the time since I had it plugged in. So evidently it wasn't getting AC power so it was on battery power. The computer turned off after the battery drained completely. When I tried to turn it on again, having it connected to AC power, the power light blinks rapidly and the computer simply won't turn on. I sent it to the repair center and they simply tell me it's the motherboard and that it will cost me $800 or more... What I don't understand is... If my computer's motherboard is fried, how come my computer was working perfectly until the battery went out of power. Honestly, what I thought at first is that there was a problem with the AC adapter :( Any ideas will be greatly appreciated.

Re: Laptop won't turn on, blinking blue light

First suggestion :
if some 1 with the same computer model can lend you his battery or ac adapter or both for a while u can then make sure if ur battery is ok.

second sugestion:
get to the mainboard
there is a jumper near the cmos battery usually shows the
word (jbat) near it , try to change its position for some
seconds while power is off , this way will clear cmos and set the
mainboard bios to default settings.
start the system hit delete or F2 to enter setup then exit saving changes.

Power light blinking on nv53a gateway

Your Gateway laptop comes with a series of LED lights that alert you to the state of your computer. You'll notice there are blue, purple and red lights that either blink or display solidly. Each light, blinking or solid, has a different meaning. The blue blinking light on your laptop indicates that it is in Standby mode. Your laptop goes into Standby when you close its lid without shutting down the computer. To turn this light off, you'll need to take the computer out of Standby mode, and if you want to ensure that the blinking blue light does not return, shut down the computer after each use.

Open the lid of your Gateway laptop and press the power button. Once Windows loads, enter your password if required. The blue light will no longer be blinking because the computer is no longer in Standby mode. Shut the laptop off when you finish using it rather than simply closing the lid to stop the blue light from blinking again. Click "Start" from your Windows desktop and click "Shut down." Change your computer's power settings to keep if from going into Standby mode when you close the lid if you'd rather not shut down your computer every time you use it. Click "Start" and click "Control Panel." Click "System and Security" and then click "Power Options." Click "Choose what closing the lid does" from the list of options on the left side of the window. Select "Hibernate" from the drop-down lists under "On Battery" and "Plugged In." Click "Save Changes." Your laptop will now bypass Standby mode when you close the lid and it will enter Hibernate mode instead. Hope it helps.

Toshiba Satellite C655-S5082. Won't power on. Worked fine last night. Today it won't turn on. Plug it it and no power light. With power cord plugged in when I push the power button the light for...


Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.

Good luck.

My laptop will not turn on even if i plug my charger in. what's wrong with it?


If you cannot see any sign of power like blinking lights, then there are three possible reasons why your laptop is acting like that.

1. Battery
2. Motherboard
3. AC adapter

Enable for us to know what causes the problem, try the following troubleshooting steps:

1. Take a look the ac adapter whether the light is lit. If there is no light then it's the ac adapter that needs replacement.

2. If there is power in the AC adapter, then, unplug it from the computer. Remove the battery of the laptop. Plug in the AC adapter, and turn the computer on without the battery on it. If it does work, then the battery is not working fine and you need to replace it.

3. If you have tried the above troubleshooting with no go. It is now the time to touch the whole computer.

NOTE: Troubleshooting 1 and 2 can be done by any computer owner. A computer owner can also open up a laptop and try fixing it but I suggest that you bring your computer to a technician if 1 and 2 does not fix the problem.

Laptop won't turn on, blinking blue light


It depends what failed on the motherboard. If the charging circuit is failed then you may indeed need a new mobo. The fact that it was working wouldn't be affected by the dead circuit as it only effects th laptops ability to recharge the battery or run from power.

Try talking to hp online tech support as they offer a $500 flat rate repair on many models. They can be access by going to and clicking the "contact us" link the the chat with live technician link.

Laptop won't start

You didn't mention the brand? First, take out the battery and plug in the AC adapter. Does it boot?
Leave the battery out of the computer a couple of hours, now put it back in and connect the AC adapter. Does it boot? If you still get nothing the computer needs to see a reputable repair person.

Power light blinks

Try using a different AC power adapter. It sounds like the laptop is not getting the proper power or not getting any at all. Have you taken out the battery and tried to power the computer on while plugged in? Also, take a pen or something similar and see if the DC jack (place on the laptop where the power cord plugs in) moves or appears loose.
