Help! My charger light blinks when its in my Laptop. and my laptop wont charge

could be just a bad battery

cheers ...

Were you able to fix the problem? The same exact thing just happened to my computer.

I'd go with another battery first.

cheers ...

Actually, I know its not the battery. I just got a new one, and I've tried it without the battery in the computer. And I know my computer works without the battery in it because that's what I did before i got my new battery. Any other suggestions?

So, the battery is ok, but it is not charging? The AC next?

cheers ...

just got a new one today. i'm not completely techtarded, i've tried opening up the machine and using an air duster to blow it out, i've cleaned all necessary contacts that i could safely get to, I've plugged in just the ac without the battery, with the battery, just the battery. I've reset the power, and nothing works. I can't get any signal light on the computer to light up, the only thing that happens is the blinking light on the charger. I bought a new charger because i thought the old one was broken, but the new one does the exact same thing. I don't think its a virus because i keep everything updated and secure.

Never implied, nor hinted :-)

I can only think next is the power module, where the power jack is, needing replacing.

What happens when you lightly and gently move the connector around, where the power jack is?

cheers ...

Have you tried to replaced the battery?

Sounds like a mainboard or powerboard issue

This has happened to me twice now with my Aspire 3680.
As per the reapair person: I "fried the power source." They said that it blinks green because the computer is "spitting the power back out." (They gave it to me in non-techie language)
I think it may have something to do with the little blue spark and popping noise that occurs when I plug the AC into the wall.

Anyways its going to need some profesional help. (The extra money I spent on the extended warranty was the best investment I ever made)

I have the same problem with my Aspire 5552-- I have concluded that it has to do with overheating, but that's just a guess / process of elimination.  It always has worked for me to unplug, cool, and re-power.  The more cooling I have (laptop cooling pad, ambient temp) the less this problem arises.

 best wishes!

Have you ever got into the fan/processor/heatsink area and cleaned out the dust....If not, over time, dust and hair can mat together around the heatsink to almost like a felt consistency..maybe time to do a serious cleaning

Oh, I've disassembled and cleaned the whole machine a bunch, and even enlarged the intake holes in the bottom of the case.  I'm next considering hand-winding the fan motor to see if I can get a few more RPM.  I'm not excited about underclocking (Phenom II triple core, but only @ 2.1GHz; with 8GB ram; 500MB Western Dig Scorpio/Blue), but I would consider disabling one core if necessary.  I'm considering replacing the thermal pads on the heat pipe, but I don't really know much about them, and I'm not sure if I can just substitute AS5...

 

other suggestions?

 

 

 

Thanks!

99.9% of the time the issue is down to a faulty DC socket... If its not soldered onto the motherboard and you can get hold of a module (ebay) you are quids in, other wise the old socket needs to come off and a new one soldered on...

How did you solve your problem with the acer laptop...it not charging?? I have the same problem with mine and don't know what I should do. Please help.

Give the above suggestions in other posts a shot?

cheers ...

I had the same problem, and this is what I've tried so far:

 

1. I had originally thought the non-charging might be a result of heating.  I am regularly in the habit of cleaning my radiator fins and fan-way.  I've even cleaned and re-pasted the heatsink/pipes with AS5 (properly, I might add), and have taken a few other steps to ensure adequate airflow.  The problem happens even when the core temps are low, however.
2. I own and use two separate power-bricks: the problem occurs with both the OEM brick (Delta Electronics ADP-65JH DB) and a decent aftermarket (Kensington) brick.  Both show steady (and appropriate) voltages/polarities.  I suppose it's possible that there is fluctuation that I've never waited long enough to notice, but that's a stretch of the imagination.
3. I have tried resetting the OS's data on the battery charge:  I have fully charged the battery, then run it all the way down to dead on battery, then held the power button down with the battery out (2 minutes PLUS) to discharge any residual charge.
4. I bought and installed a NEW (third party / non-OEM) battery.  Though it was a cheapie (in the $25-35 range), the seller had a long and nearly perfect record  (i.e., a domestic/US seller with 99.6% satisfaction across hundreds of transactions).
5. I have checked the BIOS-- it is the most up-to-date on acer's website.

 

the machine is a Aspire 5552-5898 that I bought new in Feb 2011-- less than one year ago from now-- and the problem has been happening for almost 2 months at this point!   I run Win7Pro64, 8GB with a cool-runnning WD scorpio BLUE / 500GB; I use the machine for personal/educational purposes.

 

some thoughts:

1. I can usually get the machine to resume proper charging if I unplug / wait / replug the brick from the laptop.  Sometimes this takes MANY repeats before it "takes", and sometimes my machine hibernates/dies before I get it to charge.
2. If I run either powerbrick WITHOUT any battery, the laptop functions perfectly with no hiccups.  The power and charging LEDs never flash or do anything else out of the ordinary.
3. I have wondered if the powerbrick is over/heating; I have no direct way to track temps, but I have noticed that the bricks seem warmer than I'd expect when I think to touch them (i.e. usually when I'm having the problem, and not at other times.  Nope, scratch that-- the brick was room temp (unplugged from the wall / off, sitting on the brick floor in a temperature controlled room ~70F) and I plugged it in to the PC and--voila--flashing / no-charge.
4. I have never noticed the machine to spontaneously resume proper charging without my interference.
5. When the power/charging lights are flashing, removing the battery will instantly power down the machine-- no power from the brick seems to be used to run the machine.
6. I have not bothered to test the voltages on the two batteries, but they each run the laptop for 1-2 hours under normal conditions.
7. I'm a former student of electrical engineering, and I'm very comfortable working on PCs and all sorts of appliances (electrical and mechanical).

 

 

I bought this machine because it was the cheapest at the time that suited my needs, but a 10-month usable life is WAY worse than I had bargained for-- I was expecting something like TWICE that!  I'm not sure if I'd buy another Acer machine in the future!

regarding the faulty DC socket-- (this is the next thing I'm going to try)

 

Is the DC socket doing anything other than making contacts between the two conductors (voltage and ground)?  Are there additional circuits integral to the module?  Mine has normal resistance (i.e. CLOSED, conductive), and wiggling makes no difference whatsoever.  Besides,  a faulty contact would just result in NO charging, not in weird REJECTION of charging, correct?

 

thanks!

 

(Aspire 5552-5898-- see post below in this thread for more info)

For the record, I decided that it was NOT the case that it "always works" for me to unplug, cool, repower. (see my previous posts in this thread).
