Normally teh shop should provide you one year warranty. Anyway... E71 on slim is the same thing with the fat one.
That means that your xbox tried to do an update and failed to complete it. You have the following options:
1. Reset the update to the previous status (see below instructions how)
2. Go to
http://www.xbox.com and download the latest dashboard (either on DVD ISO or for USB stick usage)
--==Console Reset Codes==--
Clear All Installed Game Updates and Console Cache (If you console get to the dashboard)
1. Go to the "system" blade
2. Select "memory"
3. Press Y on the HD symbol
4. Press X,X, Left Bumper, Right Bumper, X,X
5. A message will appear saying: "Do you want to perform maintenance on your Xbox 360 storage devices?"
6. Select Yes
Clear Any Failed system updates that cause the console to error. (If you console is unable to get to the dashboard)
1. With the console off, press and hold the sync up button (the small white one)
2. While holding the sync button press the power button to turn on the console
3. Continue to hold the sync button until the Console has booted up completely.
4. During the boot process the console should clear any failed updates, allowing you to use it normally.
