My acer aspire 7720 is only 1 1/2 years old and

My acer aspire 7720 laptop is only 1 1/2 years old and the ac adapter is loose so I ordered another one and it is even looser and falls out. So I taped it on and when I move the wire my screen shows a box that says ''do you really want to disconnect from wireless connection''. Is this a problem with the jack?

Reset BIOS? how to


With both PC and LAPTOP Motherboards,Pc Motherboards are easier to Wipe Passwords than laptops because of ease of getting to the Jumper on the motherboard normally by the battery on the motherboard.I would suggest looking online for the motherboard manual which should show you where the bios reset jumper is.Laptops are just the same but a lot harder sometimes to find this jumper. Hope this helps

7720 runs fine off battery ,but will not run off ac adapter ac adapter has been checked and has the right amount of voltage and amps


Adapter: see if you can get a duplicate adapter from someone and try theirs. Your PS has a fault which could lead to damage to the Video portion and down the road, burn out the CPU.

Acer Aspire 5720Z will not turn on please help me


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

My acer aspire will charge a battery but wont power up when i plug in the ac adapter the battery light will come on but no ac light will not power up in battery or ac


Does the laptop come on when you plug in the mains and take out the battery? If it doesn't then it could be a faulty power switch.

Acer Aspire 7720 shut down, no power light, battery and supply check good. Tried the power reset still no power light with AC supply. unit completely dead. Do I stick a fork in this one?


The laptop's AC power jack is probably damaged. All you have to do is put the fork aside :D, unsolder the old power jack and solder the new one in. If you are not good at soldering you can get it done by a qualified professional. Its a 5 minute Job and a pretty inexpensive repair.

Regards,
Sai.

Acer aspire 7720 start up problems


You need to try to isolate the problem. Try connecting an external monitor to your laptop. Press function screen keys. If you have a picture on your external monitor then you have a video problem - most likely an inverter, although you may need a new screen, unlikely but possible.

If you have no picture then you have a system problem. Disconnect the battery and AC adapter. Remove the memory and reseat. Repower your laptop and see what happens.
