charging battery/running with power cord

Richard - THE POWER ADAPTER THAT I HAVE FROM MY MOTOROLA MODEM IS: MADE BY LEADER ELEC CORP, IT IS CALLED ITE POWER SUPPLY, PIN #503913004, MODEL #M520-21120-A00F, INPUT = 110-127V 60HZ/0.25A, OUTPUT = 12.0V/750MA. ALSO, HOW CAN I GET A REPLACEMENT FOR THE 1 THAT CAME WITH THE LAPTOP?

PEACE - NICK

The XO will try to pull much more juice than that close to 1.5A which is
twice what your power supply is rated for. You can try but depending on
the design of the supply it might trip from thermal overload or worst
case burn out. Or it may just cruise right along delivering 750mA. If
it works thats enough power to run the XO and depnding on what you are
doing charge the battery at a moderate rate.

ALSO, HOW CAN I GET A REPLACEMENT FOR THE 1 THAT CAME WITH THE LAPTOP?

A system for replacement parts is in the works. There's a lot to work
out though. Right now though all you can do is RMA the whole deal.

fyi -- the power cord for the XO laptop i've seen is round, presumably with concentric conductors, and not parallel like a lamp cord. so this trick won't work.

Thanks, Paul. Please accept my apologies.

:-) :-) :-)

i don't have mine either (D1), but a friend who received his was very nice and loaned it to me for a bit, which relaxed me somewhat. the amount of feedback we're getting is a little ridiculous -- how can they not have said _anything_ publicly about slipping the january 15th date???? i know, i know. wrong forum category. :-)

Ya know? I thought I was done posting on this site. I still can't get thru to anyone with regards to replacing the original power cord. The donor services line just puts you on hold forever. Why should I have to try and build my own power cord as previously suggested? I have no expertise in the electrical field. All I need is a replacement power cord, that I paid for, to be sent to me. Do I need to call the company, Brite Star??, that shipped the laptop to me?

You can't really call Brightstar.
I mean, you can, but Brightstar doesn't have phone lines for donors/customers like you to call. They don't have a formal process for handling RMA requests from customers, and whomever answers the phone there is unlikely to know anything about the particular customer (that would be OLPC from their point of view) who asked them to ship you your XO box. They just handle the merchandise; they receive the boxes from Quanta, make sure they boot, apply the latest firmware, and slap the FedEx label on them.

The Donor Services lines (1-800-201-7144 M-F, 9am to 8pm) are run by an OLPC contractor known as PatriotLLC.

You need to either call them, or send a note to help@laptop.org.

These are the only two organizations that are authorized to tell Brightstar to ship a replacement box.

And on that note, please understand that requesting an RMA will require you to send the entire product back to Brightstar, including both the faulty power supply and the functional XO.

I'm going to try and contact your helpdesk via email since the help line is never answered. Also, I really don't feel I should have to send back the XO as well as the defective power cord. What a mess, I would have to get it back from my grand-daughter and then MAYBE get it back within a reasonable time. If the only thing wrong is the power cord,why can't OLPC send a new one? This whole process has turned into a fiasco. Here I thought I was doing a good thing by donating a laptop to a needy child in a distant land and at the same time giving 1 to my grand-daughter for Christmas. Wonder how those needy children are coping with the numerous issues, more than just a power supply. Mr, Negroponte is going to hear from me.
