It has a power pack..that goes into the wall, and the other end of the power pack goes into an opening on back or side of laptop.

I'd recommend you get a basic computer training course.

Tha half moon light blinks green,standby light also blinks with battery light orange light when charger is connected to my thinkpad t61p ,no booting


Step 1:
Try removing the battery from the back and then running it directly through the AC adapter. Sometimes the battery and AC adapter have conflicts and it can cause a laptop to become inoperable.

If this doesn't fix the problem in any way, I would recommend trying a new battery or AC adapter.
hope this helps Take the battery out, plug in the charger and see if the laptop works. If it works, the battery may be the problem. Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop. Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity. If that light isn't on, try a different outlet. Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it. If it still does not light up, your adapter could need replacing. Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery. Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection. Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.

Acer laptop shut of during power outage .


From the Acer website:

Issue
Power Issues or Will not Boot
Solution
If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?

Acer aspire 4920 charging mechanism failed


Most laptops, as in 99%, have one board and everything is on it. They don't really have a power supply since the AC adpater provides DC voltage already. There is just a voltage divider that take the incomming voltage and changes it to the various voltages the machine needs. The charging mechanism is also on the mainboard. I've very seldom seen a seperate power or charging board in a laptop. Unfortunately since you've already replaced the battery and the ac adapter and since the adapter is powering the laptop then there is definitely a problem with the charging circuitry on the mainboard. This isn't something one can repair unless you start changing micro components and ICs on the board which isn't recommended. Looks like a new mainboard or a new laptop is in your future if you want it to run off battery.

Another option is to get an external battery that mimics your ac adapter but that wouldn't give you a very long run time compared to the internal battery.

Don't forget to rate my solution in your premium thread as FixYa if you think I helped solve your problem. Thanks.

Acer aspire 4920g charging mechanism failed


Have you tested the adapter to see if there is any power getting to your notebook period. Use a multimeter to check for DV voltage. If you can't get your multimeter probe into the middle of the plug then I use a paper click to get in there. If your adapter is not supplying any voltage then there is a problem with it. I get a replacement adapter for my wife's Acer on eBay for about $30. Just search eBay for 4920g and you should get quite a few hits for the ac adapter or power cord.

If the adapter is providing power then the motherboard in your notebook is faulty since you've already replaced the battery. A replacement motherboard might be available from eBay. Replacing the motherboard could be complicated depending on your experience so I would leave that up to a notebook technician. An Acer certified shop may also be able to sell you a replacement motherboard.

I don't think it's the motherboard, my money is on the adapter. Test it out or have it tested.

Laptop does not seem to charge when I plug the charging lead in. Occasionally it will work if you twist/turn the head of the lead. Need to know if its a lead or laptop problem


Hi,

If it works part of the time, then chances are that it is a minor problem. Your options then are:
  • AC adapter plug. To check, use a DVM while the adapter is plug into the mains. Measure the output voltage while bending/twisting the junction of the wire to the plug. Voltage reading should not cut out and remain steady. If not, the plug has to be replaced and the wire cut about an inch from the junction;
  • If the adapter's plug checks OK, then it would be the jack of the laptop. Often problem would be a loose connection or a cold solder. This is a relatively easy repair, however, what is more demanding is opening the casing of the laptop and exposing the bottom side of the board in order to re-solder the jack pins to the board.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Hi when i turn my ACER 5315 LAPTOP on it runs for 5-10secs before turning off again please help thanks


Hi,


We can try some work around to narrow down the issue.

I think your notebook might be getting power from the Ac adapter. The remaining power in the battery might be giving power for few seconds and trning OFF again.

To check this, once remove the battery from the notebook and turn on the laptop with only AC adapter.

If there is no power at all, then what I guess is correct. Issue might be with the AC adapter or with the power jack on the motherboard.

If the notebook turns ON even with the Ac adapter and turned off aftetr few seconds without battery, then you have to contact service center as it could be the hardware issue.

Backup you files and documents to DVD then reload Windows using the restore DVDs or CDs the notebook came with. This will solve your space issue as well as your mass storage controller error.

Also sounds like you may need a new AC adapter and battery, both should be faily easy and inexpensive to purchase on eBay. Just search by you Acer model number and both the AC adapter and battery should show up. I would at least get the AC adapter, sounds like there is a break in your cable. I got one for my wife's Acer for under $30.

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.
