Compaq Evo n620c - Won't turn off

Cyber Akuma · 12-10-2008, 04:19 PM

I recently received this laptop as a hand-me-down, and it was basically stripped of everything.

I restored it by buying another broken n620c with the parts I needed for cheap, but I don't have an AC adapter for it yet, right now im using the AC adapter from a Compaq n1020v as a temporary measure.

The second I plug it into AC power, it turns on and boots, although since I have no OS installed yet it dosen't go far. And I found out I can't turn it off, no matter how long I hold down the power button.

So far, the only way I have had to turn it off is by unplugging the AC power.

The battery is at 0% charge and I don't want to risk charging it until I have an official AC adapter so I can't verify if it will remain on when a battery is connected as well.

Any ideas what may be causing this?

Is this laptop designed to power on when plugged into AC?

Is the power button stuck on?

Is it because I am using a different AC adapter that may be causing this?

I don't mind it staying on when on AC, but if it refuses to turn off, especially with a battery installed, or even instantly turns on when a charged battery is connected, this could be a huge problem. Even if I can shut it down within Windows (a big if since I haven't installed an OS on it yet) if the power button is broken I may not be able to turn it back on this way.

Any ideas?

The way you described it, it seems you have a shorted/defective power button. Consider opening the laptop and checking the power circuit board (if there is one).

I tried opening it, but the power button is a tiny button that is soldered onto the motherboard, I do have another broken n620c that I could take the power button off of, but I don't have anywhere near the soldering skills to do the swap.

Also, I booted with a Xubuntu livecd. I was able to go into shutdown through the os and make the laptop turn off. Pressing the power button while it was off turned it back on, but again I could only turn it off again by making the os make it go through shutdown.
