This Samsung Series 5 Ultrabook has been returned to us for the 4th time because the customer consistently complains that the notebook apparently shows graphic issues, even though we have tested it with every testing tool we have and these issues could not be reproduced. The specs are:
Samsung Series 5 Ultrabook
Intel Core i5 2537M @ 1.40 GHz
4 GB RAM
Windows 7 Home Premium 64-Bit
The Notebook was sent back to us and was tested for almost 2 weeks and the problem could not be reproduced. The steps taken so far:
Graphic test with FurMark - 3 times for 8-10 hours
CPU test with OCCT - 3 times for 8-10 hours
RAM test with Memtest - 1 time for 7 passes
BIOS updated to the newest version
Intel burn-in test - 3 times
Daily normal use tests - 7 days
- last 2 versions used and the customer says the problem still happened.
The Notebook runs completely stable when it is with us, but as soon as it returned to the customer for the second time, this problem appears its nasty little face. I have included a picture from the customer showing the graphic problems she has experienced. This problem we have not had at any time it has been with us for testing.
Maybe someone here can point me in the right direction, because we have all but expended our testing options.
