Question about Acer Aspire 7720-4428 Notebook PC

1 Answer

Battery won't charge right

I have an acer aspire 7720... for the last couple days its been having problems with charging. when it's on the battery works for a few seconds or minutes and then the battery light starts flashing and it stops charging... it charges completely fine when its off and sometimes for no apparent reason it will work while the computer is on but not for long... I've tried unplugging the charger and taking the battery out and putting it back in... it doesn't help for more than a minute

    Tell me what it does when you pull out the adapter cable and re-insert it.



    Also, turn you laptop upside-down and check the plastic where the chargeradapter goes in. Does it look like it might have overheated?

    When it stops charging, does it start flashing orange?

My dyson Max 08-21663b WHEN FULLY CHARGED I TURN IT ON AND IT RUNS FOR 5 SECONDS AND GOES OFF AND DOES THE SAME THING REPEATELY I BELIEVE ITS MY BATTERY PACK WHICH IS A 6 CELL CAN YOOU ADVISE ME?


Yes the battery pack would be the most likely culprit here. Go on eBay and buy the correct battery cells and build one using the old one as a guide. This method will save you about 50% over trying to buy a make up replacement if available. This is an easy job, just take your time, buy batteries with solder tabs.

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start


Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

I wonder if the motherboard has bluetooth integrated or I have to put an external bluetooth devise


One way to find out:
Click on the start button > right click on 'computer' > choose properties > (top left) device manager > you will see a list of drivers
Bluetooth should be near the top
IF you don't see Bluetooth, you will need to purchase an external Bluetooth receiver.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
Manual
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Button keeps blinking


It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at http://us.acer.com/ac/en/US/content/service

HOW TO ENABLE BLUETOOTH IN THIS NOTEPAD ?


The Acer Aspire is a high-performance laptop that includes a fast processor, widescreen display and an internal wireless card. In addition to these premium features, certain models also include one-touch Bluetooth access. If you have an Acer, enabling the Bluetooth is very easy and will only take a few seconds.

1.Turn on your computer and wait for Windows to fully boot. Then log in as an administrator. You will not be able to use Bluetooth under a non-administrator account.

2.Press the button with the Bluetooth symbol on the left side of the computer. This will launch the Bluetooth utility. From here you can sync and manage Bluetooth peripherals.

3.Press the Bluetooth button again to disable Bluetooth. This will disable all connections, but the utility will save your settings so the same devices will sync with the computer again when Bluetooth is re-enabled.

I hope you may find it very helpful.

How do i turn my bluetooth on?acer aspire 5044wlmi


For Acep Aspire 504x model systems that have Bluetooth built in, there is an on/off switch located in the front of the system.

For systems with bluetooth built in there will be two buttons next to each other just left of the mic and headphone ports.

The left of the 2 buttons is the bluetooth switch and the right of the 2 buttons is for 802.11 wireless.

If you only have 1 button then you do not have bluetooth built-in. You can also check to see if bluetooth is included by looking at the bottom, if Bluetooth is installed there will be a white FCC lebel with the name Bluetooth written on it.
