When I go to the Drivers & Downloads page for my laptop, there seems to be a bios upgrade to A09, however the Bios upgrade is listed for the Inspiron 5437 instead of the 5537 model.
I still tried the bios upgrade, but it is rejected as it should be I guess. Not that it's that important, as my laptop is still working great, but I just want to bring this error to your attention.
Thanks a lot.
