Most manufacturer trained computer engineers know how motherboards work alongside the firmware and chosen software so there is no call for them.
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.
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.
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
Try the following: Using your FN key and the F7 Key together it might work again. You could have toggled the touchpad off. If that does not work you have issues with either the touchpad or the operating system. Best of Luck.
This can be for a number of reasons. First thing would be to try and cold boot the device:- Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot. Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power. Hope this helps. If you need any more help then please do not hesitate to contact us:- http://www.biastechnology.com/ or TEL 01202 620955
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.
If your mouse and keyboard work properly with another computer or laptop the problem could be :
A) if devices are USB :
- defective USB port : chose another USB port;
- USB port inactivated in BIOS : check and activate;
- motherboard defective : replace motherboard.
B) if devices are PS/2 :
- damaged PS/2 ports : buy a PS/2 to USB adapter for your mouse/keyboard or buy USB mouse and keyboard;
- motherboard defective : replace it.
