Technical Support No Switch

[Dulur]

I have problems with Acer Aspire 3
EH5LP LA-H801P REV 1B can't be switched, tried switching it without the keyboard, the result is the same, but when the mainboard is removed from the casing the mainboard can turn on normally, what do you think, where are the problems? and what are the steps to solve it. Thank you

Connect all components such as hard drive and DVD RW and etc to the motherboard without a case and test. If it was normal without a frame, it probably has a connection from the mainboard to the body.
For example, it is sometimes seen that the device is not turned on by connecting a DVD RW.If this happens, program the BIOS and if it does not work, replace the DVD.
