Laptop Acer does not see AC power

my laptop Acer (TravelMate 4152LMi) does not see that it is connected to the AC power and it run the battery until it is exhausted and now I cannot use it at all.
When it still had the battery, the AC power indicator would disappear for no reason and appear only after the restart.
Now, when I plug it into AC power, the green light of the charger is lit on, the power light of the laptop is lit for some seconds, then it blinks at regular intervals (half a second after some noise, probably, of the hard disk but I am not sure) and it does not charge.

    Dear Wiz,
    Without the battery it works fine.
    Does it mean that the battery is faulty and I have to change it?
    Thank you!

    Actually, when it works on AC power, it is all fine until a sudden moment when it stops as if the electricity were cut.
    So, I suppose the problem is not the battery (or not only).

  • gskcbr Mar 30, 2008

    It really stops working abruptly and next time I switch it on, I have "to check the disk for incosistencies because the computer was not shut down properly" (on a blue screen before I can log on into Windows)
    The last time I switched it on (to try settings of hibernate) it turned off while checking the disk for incosistencies.

  • gskcbr Mar 31, 2008

    Hibernate was at 6 hours, I put at "never", and several seconds after that it switched off completely.
    (I couldn´t/ did not have time to enter into safe mode)
    And when it switches off, it is not like hibernation, it does a fraction of a second, without any preparation, as if unplugged.

AC adapter 4750z

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

Just bought a second hand acer travelmate 4200. I have never owned a lap top. How do I change from using battery power to outlet power

On the left side, towards the rear is a DC jack. Plug the power cord in there. It should automatically start operating on AC power, and charge the battery.

I cant remember the start up password for my old acer 520 travelmate how do i boot my laptop please

The older Acer computers stored their passwords in the CMOS, so all you have to do is remove the CMOS battery for 30 minutes. Here is the proper procedure to do it correctly.

Disconnect the ac power adapter and remove the laptop battery. Push the power button for 10 secinds to drain any residual power. Remove the CMOS (RTC) battery for approx. 30 minutes. Replace the CMOS battery and attach the AC power adapter only, leave the main laptop battery out for right now. Power the laptop up and let it post. If it still asks for a password, leave it blank and try hitting enter. If it accepts the blank entry and posts, then you can enter the BIOS and change your settings.

Below is the link for your service manual to assist you in the removal and tear down of components for your system.

Power up issue

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

Wireless only available when powered by intergral battery


Did you double post this question? I think you might have a hardware profile set up not to turn off wireless when in plug mode. If that isn't the case look in the BIOS and see if there is a setting in there. You could also check the power settings on your laptop.

Good luck,

Battery status LED blinkings amber

Try removing the power cable and battery, while these are removed press and hold the power button on the laptop for 30 seconds. this is called a hard reset, what it does is drains any residual power in the laptop. if this does not work, that means there is an issue with the motherboard. to have it sent in would cost about $398, give or take.
