Eject key(cd/dvd) in keyboard(Dell Studio 1557) not working after reinstalling windows.
how can solve this problem?
Are you sure, that it's a software problem?
If it's really a windows problem, try booting in fail-safe mode and see if it works then.
Maybe some CD/DVD writing applications are blocking the device. You could try to disable/uninstall those, too.
THere's a setting in BIOS. I changed mine from Multimedia first to Function first. Worked fine after that. Also installed QuickSet though and ensured AHCI was set which it was already.
