My Acer Aspire one won't turn on.

Has the laptop been damaged? Dropped? Same on battery? Remove battery, try AC only. Try another cord/charger with the EXACT same power specs. Reseat Memory mods. Test the DC volt output, at the laptop plug in, with a multimeter. Power issues are difficult to diagnose long distance.

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.

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.

Unfortunately, if the light is on, but the computer won't power on, it means one of two things. Either the power cord is broken in some way and no long sufficient to power the computer, OR the motherboard is dead. You can try to purchase a universal cable from Best Buy for instance, and then return it if it doesn't solve your problem. A motherboard repair would be best done through Acer themselves, although, it can cost over $300.

Unplug the power cord then press and hold the power button for 20 seconds. Plug the power cord back in and press the power button. Did you see any lights or hear any fans? If not, the power supply is probably bad.

most likely a motherbaord problem.

unplug power cord, take out the battery.

hold power button for approx 90 secs.

try to power up the laptop again.

if this fails then try a new power cord, that could be also faulty and not regulating the correct power output

Turn your computer off.
Make sure both cords from monitor are plugged in.
Make sure you have pressed any required "on" button on front or side.
Try your monitor on a friend's computer.

Tell us whether or not it worked there and what kind of monitor it is.

U ARE HAVING PROBLEM WITH UR POWER CORD OR YOUR BATTERY

disconnect the battery from the laptop and only hook up the ac adaptor. Turn the laptop on and if it still cuts off after 5 seconds then reseat the memory back into its slots. Also make sure your air vents are not clogged with dirt or dust as lack or air flow can cause the laptop to shut off. If that doesn't do it then take out the hard drive and dvd drive and turn on the laptop. If the laptop still cuts off then it has to be a faulty motherboard at that point which means to much voltage is going thru and the components on the motherboard are not regulating it properly.

If you dont see any green lights and you dont hear any boot up sounds ( hd, fans, etc) try to take out battery and just plug in the AC adapter to a known good power outlet. Make sure your power plug is good too. If you hear boot-up sounds, see green lights but no display then toggle on the "fn" key and or try on an external monitor.

take out the memory from bottom, and battery, plug into wall, and try again..
