Help! (again) Acer ASpire 5100

Hi

Likely need to chat with ACER support in your country as manual for that app does mention you need to take to a Acer Customer Service Center. I have an ACER laptop and that app was one of the first I deleted as the potential to lock yourself out was too easily done, just thinking aloud and iirc e-lock was run from boot, so get yourself StartupCPL and look for anything called elock in the startup lists and disable, "may" give you back use of the drives temporarily, but you would still need to speak to ACER as e-lock would not be working if disabled from startups.

As for sound drivers, how long ago did you accidently delete them? Was thinking a system restore back to before you deleted them may work, but easy option is to download and install them again from here http://support.acer-euro.com/drivers/notebook/as_5100.html (XP is Audio 5.10.0.5273 and Vista its Audio Realtek)
