It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.

My Acer 6800 on button light comes on, wont shut off! Wont boot up all the sudden!


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 laptop acer extensa 5420 doesnot turn on. The power switch light went i hit the on/off switch?


Sounds like the motherboard. Take the cover off the tower and when turning your computer on inside there is a green light and if it goes to an orange light and stays flashing the motherboard needs replaced

Problem with emachine m5124 startup


Take the battery out and unplug the power cord. Press down the power button continuously for a solid 30 seconds without stopping. This drains all the power out of the circuits and resets whatever invalid state your computer is in.

Now, leave the battery out but plug in the AC and turn on the laptop. If it works, turn it off again and insert the battery. All should be well.

My computer would not take a charge, so I bought a new battery, but it still want charge. What else could be the problem.


I'm confused.. you post this question on the pc desktop session... desktops do not have a battery... did you mean the power supply maybe??
if you actually have a laptop and you purchase a new battery please provide details on the lights that appear on the front of the computer when the computer is connected., there's a power light when the computer is plugged and a battery light that when charging is yellow/amber and when fully charged is green or blue.
if you in fact have a laptop and just replaced the battery depending on the lights you see in front it could be the connection on your computer attached to the motherboard right where you plugged your power cord, it's a fairly common problem that that little piece eventually starts crapping out on you. you need to get a replacement (ebay) and have it soldered onto the motherboard.. pay for it if you don't know how to do it.. it's a fairly delicate procedure.
again, depending on the lights you see, the othe problem could be your motherboard and your bios, flashing the bios may be something you may want to try.

post more details to see if there's something else that we may suggest.

My lap top turns off *** soon as i remove the power cord.... its like my battery will not take charge at all.. the battery light flashes 2 green and one orange... its a dell 9100


Dell has problems with that motherboard not recognizing the battery or the adapter. If you get error messages about the battery not being correct or recognized, the board has issues.

If this notebook is always plugged in then the battery has shorted and won't hold a charge.

Best option is to try another battery. Another thing, if your system is more than a year old, the battery needs replacing anyway.

If you are going to use this plugged in, get another battery, charge it up and remove it.
