Question about Acer Aspire 7741z
Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.
Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.
2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.
3. If replacing the laptop charger and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

This is a sample of what you can try to do to diagnose a non-starting computer, If these don’t work, realize that most likely a system board (motherboard) has failed or the actual power trim strip above the keyboard has failed.

It sounds like your computer's charging port is disconnected from the motherboard. The charging port cable probably has to be re-soldered to the motherboard to be fixed. If you are not skilled in computer hardware repair-ale I would suggest going to a computer technician.

Hello there and thank you for choosing fixya
This is a fairly common problem
Ok what you need to do is first turn off the laptop
then remove the battery from the laptop then after the battery is out
press and hold in on the power button for 45 seconds (this allows for the esd to be released)
Now get the power cord and plug it in *** NOT HE BATTERY YET***
NOW try to start up the computer it should start up ok now if so great let it boot fully then attempt to shut down normally then replace the battery and you should be ok
If not then immediately unplug the machine then you will have to try 1 of 3 things first is to remove all the memory and then see if it will start if so replace the memory 1 at a time then start up after each memory module has been installed you may find it wont boot with 1 of the memory modules if so that module may be bad ok?
Please try these things first let me know so i can proceed on if i have to
Best regards Mike

On your desktop press the following key conbination: Fn + F7 if not, there must be a problem with your mouse pad. It might also be that your OS takes time to load or freeze and it make it look that the mouse is not working. You can also try and external mouse.
