Have you tried to increase the brightness while it's plugged in. Use the fn (function) ket plus the key that corresponds to increasing the LCD brightness.

usually it's the other way around. When plugged in the LCD brightness will increase and decrease when unplugged to save battery power!

Its not a problem, its how it was designed. With the power cord in it will be at full power so it will light brighter, When the power cord is out, it will be less bright as its using power from the battery , it will light dimmer to conserve power.

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.

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

. 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.

I had a similar problem and I had to "Delete Volume" when in DIsk Management. I then had a choice to "Create Simple Volume" which I did, and then a wizard created the correct partitions and assigned a drive letter to my external drive. Everything was them OK.
