Replace the hdd as unless you can prove ownership of the media, Gateway will not release the code.

I get intermittent sound from the right hand speaker on my gateway 400sd4 laptop.


Could be the speaker is on its way out, you could try re-installing the sound drivers by first un-installing them then re-installing them and play some music see if its made any difference if not you may need to take it to a repair shop. hope this helps.

Forgot CMOS Password


Try leaving it blank see if that works first. If that don't work you may try to type in microsoft in the user name, and leave password blank, maybe that will work, If that don't work there are password retrieval disks you can buy, or you may have to reinstall the operating system, By doing a full OS (Operating system) restore. you will loose all info that was on the laptop, I sure Hope that Helps you out, If you need something else just ask here, thanks bear001
