Hope this helps.
I, too, got my 4780 back from repair with said
sticker.

The warranty company (Phillips(?)) had me send it to MicroMedics, in Illinois if I remember correctly. Took 4 months!
Background:
The "standard 3-year warranty" at the time I bought it from PowerNotebooks. My computer had a meltdown 1 year ago. 2+ years into the warranty.
Just recently I found out that a contractor disconnected the GROUND WIRE of the cable block outside my home. A high voltage spike on a transformer nearby traveled through the cable. Since there was no ground it traveled up through the cable modem, the network router, finally into the motherboard which immediately caught fire. (If you ask how -- the cable was plugged into the TV tuner! )
This was about the time Dell and others' batteries were "blowing up". So I decided to remove the battery.
(A note: my previous Sager laptops were all easily replaceable.) I sent it to Micromedics missing a cover plate screw.

- Oops! Thought this smily was "put-finger-up-nose" - duh)
Big mistake -- They refused my warranty claim based on their assertion that I "opened" my computer, thereby voiding the warranty.
The standard 'no user serviceable parts’ mentality. Unbelievable? Believe it.

They wanted $1200 for parts, they would pick up the labor and shipping both ways. Since I lost "it" and threatened lawsuit for breach of contract; they would either return the computer, in pieces, or wait until they received a cashier’s check. Good business sense?? Probably, since the warranty cost < $300.
Short moral to story:
NEVER threaten lawsuit.

- You'll end up cash & carry.
Because of the
sticker, I
can:
- NOT replace the battery.
- NOT add additional RAM.
- NOT replace the DVD/CDROM.
- NOT replace the HDD for any reason.
All of which were possible with my earlier laptops, and
acceptable to Sager, at least when my 4780 arrived with bad RAM,
which lasted one day, which they exchanged and which I removed/reinstalled.
- Can replace the keyboard. (But don't admit it.)
- MUST: Return it to Micromedics for all the above.
DUH!

- I can repair jet engines but not remove screws!
Long Winded Moral to story(1): Please read the details of the warranty contract within your "no-questions-asked" return period. Understand the limitations and what you MUST/MUST-NOT do to keep the warranty intact.
PS to Charles[at]PCTorque: They returned my 4780 WITH a generic BIOS (no fans control!) and the
sticker. Sager emailed me the "proper" BIOS. I installed it successfully, but; (1) The
FN/CTRL key swap no longer works and the fans are either on all the time or not, in the BIOS setup. I have yet to determine whether I got a different BIOS EPROM on the new motherboard.
BTW - Micromedics did their own work to my knowlege.
PPS: if anyone still wants the FN/CTRL key upgrade, I may be able to find it. A private message if you do.
PPPS:

- Does anybody remember which motherboard is used in the 4780?
Whew!!
