Acre Aspire -- 3000 series notebook -- Power adapter issue

problem in mother board power supply unit check any dry soldering

Try wiggling the plug around a bit to see if you can get contact. You could also try borrowing a power supply if you know someone with the same machine to isolate the problem.

Hi there,
This issue is going on quite a lot but It seems to me that currently there is no choice but to try a known good working adapter. Because the BIOS wont update or Flush(if you would install the same version) without the AC adapter.
Faced a lot of this issues with DELL laptops so hopefully the replacement adapter would work.

= if your laptop computer will not start =
laptops have power supplys that can lock up
the power adapters conectors break all the time 
and the batterys are designed to be "con$umable$" 
so 

- - -- - -- - -power reset - - -- - -- - -- - -
remove the power adapter's wall plug & 
leave the power adapter plugged into the computer 
but pull the laptop battery out of the laptop.
press the power button just like you are trying to start it 
but press it longer, this will drain & reset 
the internal supply, now relese the button.

-- - -- - -power adapter only test - - -- - -- - - 
reconnect the power adapter's wall plug 
press the power button to start it with just the power adapter , 
If the power adapter starts the laptop on its own go down to  
"If the computer can be started"

If the power adapter does not start the laptop on its own 
leave the power adapter plugged into the computer but 
remove the power adapter's wall plug & press the power button 
just like you are trying to start it again, 
then relese the button 

- - -- - - battery only test - - -- - -- - - 
unplug the power adapter & put the battery back in  
press the power button to start it with just the battery

if the battery starts it on its own go down to 
"If the computer can be started"

if the battery ALMOST starts it on its own 
DO NOT BUY A NEW ONE! it may only be discharged 
locate another laptop just like yours and charge it, 
and yes this is crazy and yes i am sorry!.

- if your laptop computer cannot start at all - 
- - - - - - - - - - - - - - - - - - - - - - -

this can be caused by a bad; 
connector ($5-$60), power adapter($5-$60), 
battery ($70), internal supply ($40-$90), 
or main/mother board ($100-$300)

If the internal power supply is bad or if the 
power conector fails at random (intermitant) 
most of the cost is determined by how dificult 
finding parts and dismantling the laptop is 
and if it's external or internal 

Just plug the computer into the wall with the supplied power cord (while the battery is in the computer). This will charge your battery.

I would replace the battery if you had for some time. Over time charging a battery will slowly not take a charge. If you tried two adapters, about the only thing is left is the battery.

Is the connection loose? If so, that means that your DC Jack will need to replaced or resoldered. Unfortunately, there is no other way to connect a power adapter. You will have to get it replaced. We see this in my shop all the time, unfortunately.

Did the battery seem to lose it's charge rapidly prior to this, this would be an indication of a battery losing it's useful life, or a problem with the charge system.

Have you tried to take the battery out, plug the computer to a wall outlet granted you have the power adapter which is the same as the charger cord I would think. If that works I would say you need a new battery. Sometimes the plug port where it connects in the computer wears, so try and wiggle the cord if you didn't get something the first time.

Try removing the battery..then attempt a power up. make sure there are no USB devices connected as well. Take some time, it happened to me, it was caused by a non USB compliant lamp! The machine would not start at all.

Unplug you ac adapter from the wall and plug a lamp in to verify that the wall plug is working correctly. Pick up the adapter to see if it feels warm. Most adapters will feel warmer than room temperature if they are working,
If the cords on your adapter can be unplugged from the adapter, reseat them. Try the ac adapter in another wall plug to see if it comes on. The adapter may have an LED on it that indicates whether or not it is on. If it doesn't, about the only way to check it is to use a multimeter to see if there is any voltage on the plug that goes into the back of the laptop. If something else will work in the original wall plug and the adapter won't work in another wall plug, you will need to obtain another ac adapter.
Once you've tried these things, let me know and we'll go from there.
Thanks!
