Flashing battery power LED

I noticed that the battery indicator had a big red X through it. I powered down the laptop and it wouldn't boot up again. The battery LED flashes amber several times but no boot up. Have taken out the battery to use AC power and when this is done, there is no activity at all (not even a flashing LED). Is this a battery problem or something more serious (possibly motherboard?)

Try this

1. Remove the battery and the AC adapter. Hold down power button for 5 seconds. then insert the AC adapter only and see if you can power up the laptop. if it does power up, dont use the Battery anymore as it might be the cause of the problem

Plug into outlut but screen and power buttons dont light and dvd player doesnt work


Do you get any indication that the laptop is trying to boot - do you have a Power LED that is lit, any other LED indicators that flash at all?Have you tried to connect the laptop to an external monitor and if so, do you get any error or progress messages shown on that display?If the laptop will not power on at all, then try removing the battery then plug back in the power supply and see if it will boot with the battery pack removed.

My sony vaio vgn-nw320f was totally dead.i had pulled up the battery cause it could not log off.please help me.....


Most sony laptop power supplies have a power LED that indicates if the device is A) plugged in {ok it happens!}, or B) fried and not providing power to the laptop. Check this first. If the power supply is plugged in and the LED is on (usually green or red) then see if you have ANY lights on the laptop itself. Its possible that your LCD display went bad but that the laptop is otherwise running. You may see a power, hard drive or wireless network light on if the laptop works but the LCD went bad. You can also connect an external monitor to the laptop and power it up to check the LCD.
I've also seen where the battery goes bad and it keeps the laptop from booting. Try removing the battery and power up (with the ac adapter plugged in) again.
If neither of these helps, you may be looking at some kind of internal short on the motherboard which is big money. Hopefully that isn't the case.
Hope this helps!!

The main unit beeps every 30 seconds


This is battery related. On top of your unit is a battery pack with three colored led lights. You can tell what is going on by looking at these. This information is in your manual or here it is.
GREEN LED: All systems are normal. A solid LED light indicates the batteries are fully charged. A flashing LED indicates the batteries are being charged. NOTE: Batteries do not have to be fully charged to operate the motor unit. YELLOW LED: The motor unit has lost power and is operating off of the BBU. A solid LED with beep, sounding approximately every 2 seconds, indicates the motor unit is activating the door and is operating off of the BBU. A flashing LED with beep, sounding every 30 seconds, indicates batteries are low. Once the power is restored the BBU will recharge. This is indicated by a flashing green LED. RED LED: An error has been detected and the BBU will automatically shut off. The BBU will attempt to restart by reconnecting to the batteries. If the error is still present it will shut itself off again. This process will repeat every 5 minutes or until the error has been resolved. This is used to prevent further draining of the batteries. If a red LED remains on when the power is restored, and is accompanied by a beep sounding every 30 seconds, please call for service.

3 lights o right hand side of laptop what do they mean


The user manual will supply an in-depth explanation of the led-indicators, aswell as there are normally small icons assigned to each light, sometimes engraved in the plastics, normal lights to be active at average usage are the Power led indicator, will glow as long as device is turned on, the Wireless led indicator will glow when the wireless network module is active, the CPU led indicator will flash occasionally when system is idle, and rapidly when system is active under load, and the Battery led indicator will be active when device is running on battery power. When device goes into sleep or hibernate mode the sleep led indicator might continuously glow or slowly switch on & off varying between systems.

Batt light flashes 4 red and 1 green over and over vostros laptop


Hi there. If your battery light is flashing 4 red and one green on the battery light indicator (as in the one next to the power and hdd led), then this is an indication that your battery is nearing the end of it's life, and it's time to get a new one. It will last a bit longer, depending on how much you use your laptop, but there will come a time when it won't work at all.

Power problem


Seeing as you notice that your battery life is half, this most likely means your battery is no longer able to hold a charge, or a full charge. It could also mean the battery is defective.
If your laptop is still under warranty, the manufacturer may replace it. If not, you'll have to buy a new battery, unless you always keep it plugged in anyways.

My ibm thinkpad booting and hanging fault


Try this... to see if your video card is bad...
Connect your laptop to an external monitor and press the Function key plus F5 on the laptop... if your OS shows up on the monitor screen, then you have a bad video card...

If its not the video, Bad Ram might be the cause.
And worst case.. Need Motherboard replaced...
