1  Hardware and U-Boot firmware / Hardware / Re: Is my sheevaplug dead ??? on: April 12, 2010, 05:37:29 AM
My plug died today (about 9 months old) - the LEDs don't light up. I opened it up and checked the output of the power supply with a voltmeter and it seems to be delivering about 4.8V fine. So that doesn't seem to be the problem.

Does anyone have any other ideas what it could be, or how I could check?


EDIT: I noticed that when I flick off the power, the LEDs would light up for a second. When I was checking with the voltmeter, the voltage would die down then spike up to over 5V for the same time, after turning off the power. So it was the power supply after all. I wired in an old wall wart and the plug lighted up. Phew!

Someone should design a new casing for all of us with dead power supplies. A plug with a plug looks ridiculous!  Tongue

Interesting, thanks. I don't have the hardware, though, and was just hoping to check the CPU temperature or something like that. Yesterday was another hot one (34C) - I put the plug under the desk and on its side and it survived. Today and tomorrow will be hot also, so we'll see!

Hi all,

Summer is coming in Australia. Today the temperature hit 30C and my plug, which has been working well up to now, reset itself Sad  How can I monitor the plug's temperature? And if you have advice for keeping it cool, I'd be glad to hear it!

(I'm assuming the two events are related, of course.)

Probably useful to provide a diff Smiley

Works great Smiley Installation took maybe two hours without any prior experience with the plug or TFTP.  I used a couple of scripts from slackbuilds.org to install a few extra packages; you just have to set ARCH=arm.

Ordered mine 17 May, not yet shipped.  I sent an email today, and got a generic sounding response about 4 weeks delivery (uhh..). Apparently the next batch is expected 10 July.
