[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system equipped with an uninterruptible power supply.

[0002]

2. Description of the Related Art Recently, with the spread of workstations, personal computers, etc., even small computers have come to be able to sufficiently exhibit their performance. Are often used.

In order for these computers to operate normally, it is necessary to constantly supply stable power to the computers. For this reason, a high level of stability and reliability is required for the computer power supply, and short-time power outages are often unacceptable.Therefore, when a commercial AC power supply fails, an energy storage device such as a storage battery supplies the computer with power. An uninterruptible power supply system that continuously supplies electric power is used.

By the way, even if such an uninterruptible power supply is adopted, when the power failure is prolonged, the capacity of the energy storage device may be exhausted and the original uninterruptible output may not be continued.

Therefore, in such a case, it is considered to carry out necessary measures in advance by transmitting corresponding information between the computer and the uninterruptible power supply. For example, it has been considered that the computer and the uninterruptible power supply device are connected by a communication means, and various kinds of information transmitted to the computer cause the computer to shift to a system stop state in preparation for a power failure.

[0006]

However, in such a configuration, when the uninterruptible power supply is restored after that and the power supply to the computer is resumed, the computer side remains in the stopped state in preparation for the power outage. You will receive power,
Depending on the application of the computer, if the operation is stopped midway, it may not be necessary to resume the operation after the power recovery, and there has been a problem that such a request cannot be met at all in the past.

The present invention has been made in view of the above circumstances, and is a computer that prevents a meaningless computer and an uninterruptible power supply unit from restarting operation after a power recovery and can easily shift to a system state desired by an operator. The purpose is to provide a system.
