Abstract

Disclosed is a method which enables a home computer to power-on and restart its services without being exposed to erratic power outages. Following user-specific basic input/output system (BIOS) settings, after an initial power outage the computer continues to monitor for subsequent power outages until a user- designated period of time has elapsed. After the designated time passes with no further interruptions in power, the computer safely boots-up without negative effects to the user’s services or files.

Method For Automatic Recovery Of Computer Systems After Power Outages

Today, more people are hosting services on their home computers for remote access. These services allow them remote access to the music, videos, and pictures, stored on their home computer. When one has convenient access to their home computer, they don't have to worry about forgetting to copy an important document onto their flash drive before leaving the house. It's good to know that they can always access their home computer remotely to get the document.

Most computers are configured to remain powered off after an unexpected power loss. This is usually done to protect the computer from further damage or data loss that may occur during subsequent outages (such as during a thunderstorm). The disadvantage is that if no human is around to power on the computer, the services hosted by it remain unavailable.

For example, if a user is half way around the world from their home, and would like to access their computer, they would be unable to do it after an unexpected power loss at their home. Here are some reasons why:
• For non-critical home computers, it's not worth the money to buy an expensive Uninterrupted Power Supply (UPS)

which would enable the computer to safely

shutdown.

As computer central processing units

                                (CPUs) consume greater levels of power, the UPS systems required to keep them running for even just a few minutes cost hundreds of dollars.
• Most computer systems can be programmed in the basic input/output system (BIOS) to power-on the computer based on a schedule, or to power-on when a network signal is received (e.g., Wake On LAN) over the Internet. However, these BIOS functions do not work after an unexpected power loss. In such situations, a person must physically press the power button to turn it on.

Alternatively, it is possible to configure the BIOS to power the

                                        system on immediately after the electrical power is restored, but this exposes the computer to subsequent, and possibly erratic, power outages resulting in data loss or system instability.

Some mechanism is needed to power-on the computer without human intervention and

without exposing the computer to the instability of power outages. If a user is away

from home and the computer suffers a power outage, a system is neede...
