    I was thinking the mother board was toast. I've tried it with just the power cord and no battery with the same result. I can try a different battery.

Battery light just flashes on acer aspire 5155 no power


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

My dell inspiron mini 10 won't boot.There is just a flash of white light then a flash of amber light when I press the power button. That's it, nothing else.


Remove the main battery and try again, also! the power adapter charger should be checked for correct voltage, if okay! pull one stick of ram and test, and the second piece not forgetting to put the first one back and power up, if all this fails you will need to get it assessed.

Gateway M-6862 laptop will not turn on; battery light flashing re


Seems to be a problem of not enough power.

First check the voltage output of the charger(adapter) and match it with its specs.


Also try to reset the hardware using the following steps:

1 Disconnect battery and the charger
2 Let it sit for 1-2 minutes.
3 Press and hold down the power button for 30 seconds.
4 Reconnect battery and charger and try to start by pressing the power button.

C500 Laptop won't come on power button just flashes


Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

Laptop wont boot and the battery and power lights flash


a simple power cycle might work. Take out the battery but keep the ac power connected. hold the poewr button down for 1 minute. then hit the power button again and it should poewr back up. If this doesn' t work. iyou said hte battery light flashes so the problem isnt the battery..the problem might be hte ac power adapter..if you have a warranty this would be a good time to call them. Try the power cycle first though this fixes the problems lots of the time
