MRS Upgrade from 500 to 800

Question

Hi Gurus,
For a client we are going for ECC 5.0 to ECC 6.0 upgrade with EHP 5 and as a part of this upgrade we are going from MRS 500 to MRS 800. Could you please let me know are there any difficultues to go from MRS 500 to 800? During configuration, migration activities are there are any specific steps needs to be followed. Currently we have migration and configuration docs from SAP site for MRS 700 and one document on the overview of MRS 800.
Pointers are really helpful
Eagerly waiting for your reply.
Thanks in advance.
Regards
Satish

Hi, and welcome to Apple Discussions.
That was a bogus reason given by your Help Desk folks. If the iBook was purchased in 2002 and stored in a cabinet for 3 years, there's something more going on here than the expiration of the the iBook Logic Board Repair Extension Program, since it did cover the iBook for three years.
Sometimes if you call the number on the FAQ page and ask for Customer Relations (Customer Service can't help you out, here), they will grant you the courtesy of making an exception to the 3-year rule and will authorize a repair if you ask.
If that doesn't work, and you are a hands-on sort of person, the following do-it-yourself fix, posted in the Displays forum by John Sawyer, may work for you:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.

I wouldn't advise replacing a 600 MHz logic board with a newer one, but you could check on the Accelerate Your Mac forums and see if anyone has managed to pull it off.
Good luck!
