This is similar to being incommunicado. The user is not able to communicate through e-mail. This condition often afflicts those whose computers are infected with a virus, or whose internet providers are not functioning properly.
Sorry, Fred, I was unable to reply to your e-mail this weekend because I was incomputerado. OR Oh, oh! I want to check out this website today but my PC is in the shop. I'm going to be incomputerado until at least tomorrow
