Acer aspire one. 3days old. flickering

how old is your laptop?

The DC jack in the laptop is showing early signs of intermittent issues, the jack is solded to the motherboard which sometimes breaks free over time, this is something that will eventually need to be addressed.

DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

Sorry. It seems that your battery is dead.
If your laptop is working fine on AC power only (with the battery disconnected), then your battery will need to be replaced.

if it doesnt hold a charge its degraded and will need to be replaced . people dont realise that keeping a laptop plugged in damages the battery

it sounds like your laptop's battery has a reduced charge cycle. I recomend charging it to full then letting it die 3 -5 times. (to completely die means that it wont turn on at all. usually this takes a couple of times turning on to be sure.) this should reset the internal memory there by restoring its charge capacity.

You have two problems and they are separate issues.
First your battery is nearly worn out. Rechargeable batteries have a finite number of charge and discharge cycles and as the battery ages the charge capacity will drop. When the battery is worn out, it may not charge at all or show it is 100% charged but when you remove the AC power the laptop will shut off because the battery is dead. A new battery is required to fix this problem.

Second when you connect the AC adapter into the laptop's power socket, and the screen flickers and the charge LED also flicks, it means the power socket is faulty or the power socket has a dry solder joint connection to the motherboard. If you hold the power plug in a particular position you should notice the charge LED will stay on without flickering as well as the LCD screen.
This fault can be repaired, but it requires the laptop to be dismantled completely to access the power socket. I suggest you get a quote first.

Hello,

It really sounds like you have a short in the ac adapter. Laptops dim the backlight on the screen when on battery power and go full brightness when on AC. I think your adapter is going on and off. When it is on the screen is on full and when it goes off the screen dims down a bit. You could have a bad adapter, most likely, or a bad charging jack in your laptop. Check the adapter first, just use a multimeter set to voltage. Read lead goes to the center pin and black lead goes to the outside metal contact, you should get a reading of 18 to about 26 volts. Move the wire around near the plug that you are holding and keep checking the readout. I think you will find the voltage dropping as you move the wire.

I hope this helps, If so please rate my solution.
