here is my situation: I have an Aspire A315-41 that I use with an external monitor and an external wired keyboard. The laptop is closed and positioned below the monitor stand. I want to specify that I googled for 2-3 days before posting this question, but I didn't find any possible solution.

So basically what I'd want to do is to power on the pc from a state that can be the standard shutdown or an hibernation (NOT sleep nor hybrid sleep), without pulling out the laptop, opening it and press the power button. I tried every possible configuration to wake the system pressing a key with the external keyboard (which would have been the best solution), but none worked: the usb ports are powered off, so hitting any key does nothing. I think I'll have to stand to the idea that this is just not possible.

Do you guys have any ideas on how to achieve this?

P.S. I'd want to avoid to sleep the system because I think (correct me if I'm wrong) that keeping the RAM used for all the time and never completely shutdown the laptop isn't too good...

You may do that from your network and using another device, which may be another computer or even your phone. This is called wake-on-lan.

For the prerequisites and required setup, see this answer.

For phone applications, a quick search found one app for Android and one for the iPhone.

  • yeah I already knew about that, but isn't it only for waking the system from sleeping? I don't think it works if the laptop is hibernate/powered off.

  • It is also applicable to powered-down state if you network adapter is capable of "listening" to incoming packets in low-power mode.

  • I don't think so, anyways it's not a possible solution since I'd have to connect the laptop via an ethernet cable to the router, which is not possible in my case unfortunately

  • All the phone needs is to be on the network, meaning be connected to your router, which is probably the case.

  • I didn't mention the phone. WOL requires that the laptop is connected via cable to the Ethernet port: currently I'm using the wireless adapter, since the router is too far (no, I can't change its position).
