Try a hard reset. This is done by disconnecting everything connected to you laptop all power and all usb and cables. Then remove the battery and hold the power button on for 60 seconds or longer . This is to drain any residual energy from the laptop and for the mem to clear. Hope this helps

then restart laptop after connecting power and reinstalling battery
If this doesn't work you may need to check out your power connection in the laptop to see if power is getting in

I Know how to solve that!
Unscrew every single screw that you find from the bottom(remove the battery,then the cover that covers the HDD,then unscrew and remove the HDD)then with a knife detach the keyboard and the trackpad,(Don't pull the keyboard to much because there are some connected cables)Detach all the cables,then find where the power button connects to the motherboard.Short all the pins of the port on the motherboard several times until you see lights(remove the battery but plug in the power otherwise it will not work)(To short pins use anything of metallic,it works even with a pen).
IMPORTANT!!!
If you're not sure about how is this done go look a teardown video on youtube,so you can have an idea about how to get to the motherboard.

Can you describe more on how to short the pins, my power wire are attached to a card that snaps into the motherboard. I just don't want to mess up shorting out pins!

That shorting trick worked for me... A real miracle after I got desperate to power on my X550C laptop.
So does it mean that the ribbon is bad or the button board?
Also it seems that I have to do it every time or with power adapter will the button switch on the laptop? I did this with only battery because I left the power adapter at work.
Thanks for your useful tip!

i’ve been experiencing the same problem. charging was fine but power button was totally dead. turned out the mobo - power button cable was loose. no issues since then.

Hi Dan
The same has happened to me. The laptop crashed so the only way to shut down was to remove the battery pack. After that I reinstalled the battery but no power. Plugged in lower, no lights nothing. Nightmare.
Have you been able to fix it?
Thanks,
Liam

*power not lower
Try disconnecting the video/display cable from the motherboard; then test to see if you can power the unit. May have a bad display.

i had same problem. to check on/off power switch on asus x550 ca remove keyboard. power switch button is at the top left. it has a ribbon cable (the shortest one). if you follow that ribbon cable to the motherboard connector, the metal of the ribbon in the connector can be seen. with a small flat bladed screw driver, gently run the blade accross them. this will short them and signal the start up. if the switch /ribbon is bad the laptop will boot (with or without keyboard, hard drive, display connected)

Nice trick bob0008943! Shorted my power button cable connector on the mobo and on she came. Tells me I need a new switch. It looks like the cable is crimped to me.

In my case the power jack was broken and need to be replaced.
