Can you please tell us which notebook model do you have exactly and what happen when you press power button?
Don’t hold anything, just switch notebook on and describe what happen exactly?
Which operating system is preinstalled on this Equium notebook?
The RAM modules are placed at the bottom of the unit. I think you should find detailed info in user manual.
As I mentioned above: remove one module and try to power up the notebook using one module in one slot. Run this test for both modules in both slots.
Of course this will not help you if motherboard is faulty or both RAM modules malfunctions…in such case the technicians should check the hardware using special tools.
