Have an emachine M5105. I plug in the power cord, the light won't stay on but for a few seconds. The battery won't power up. I now cannot turn my pc on.....now what

The battery might be dead. Batteries only have a useful life and after that they have to be replaced.

Does your laptop work ok off the AC Adapter Power Cord? If so, your battery is dead and your power cord is good. If the laptop does not work off the Power Cord then either your Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. In either case a good battery will not charge if the power cord or the DC Jack is bad.

Check your DC Power Jack which is where the power cord plugs into the compute. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Give us more details on what happens when you hit the power button. Does it try to turn on? See any lights or hear any beeps? Hear any fans?
If you really want help give details to get a solution.


Remove the Power Cord, Remove the Battery, Remove the Memory Cover 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.

Try A Hard Reset

Remove the battery and charger/ac adapter/power cord from your Sony Vaio laptop, press and hold the power button for 20 seconds to discharge any residual current inside the laptop.

This clears your RAM and is like a hardware reset.

Replace the battery and charger/ac adapter/power cord
and turn your laptop on.

If that does't work try removing ram and reinstall. Sometime this works with these laptops.

either a bad battery, or charge port. even if the battery was fully charged it will still keep the light on, try this. plug it in, and power it on, then remove the battery completly, the computer should stay on, as its running off the plug power cord. if this port is a bad one the pc will shut off immeadatly. and if it stays running then it will be the battery.

Remove the battery and just leave it off the computer, then plug in the power cord and try it. If it works with no battery...the battery is completely dead and you need to replace.

Did you flash the main board ??

1.) remove battery
2.) press and hold the power button for 10 - 30 seconds
3.) replace battery.
4.) when the system boots it will say press XX (e.g F2) to load defaults and continue ,, press that key.

It could also be the power button is stuck!.

find were it connects to the main boad and unplug it
bridge the 2 pins it jacks into to turn the computer on. if it works u will need to replace that button or the case.

The eMachines M5105 is notorious for failing to boot if left unplugged and powered off long enough for the battery to become mostly discharged. Plugging it in to AC power will cause the battery to start charging; and the hard disk drive to spin while the CPU cooling fan cycles on and off vigorously. THE UNIT WILL NOT BOOT UNTIL THE BATTERY IS NEAR FULLY CHARGED; then THE AC DISCONNECTED; and then THE (charged) BATTERY REMOVED AND RE-INSTALLED! Most units will boot after following the foregoing procedure.

i suspected the IDE cable is not properly connected to your hard disk. Check connections and boot up machine normally.

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.

The laptop is in sleep mode. Take the battery out,then plug in the ac then as soon as you do hit the F3 key and wa la   it wakes beck up..

Best wishes enjoy.........emachines got to love em to play with em  !!
