## Abstract

An information handling system may include a host system including at least one host processor and a basic input/output system (BIOS); and an embedded controller (EC) including an EC processor. In response to the information handling system receiving an instruction from a user to initiate a forced power off, the EC may be configured to: store diagnostic information indicating a state of the host system; and upon a subsequent boot of the host system, transmit information to the BIOS indicating the forced power off.

## Claims

### Claim 1

An information handling system comprising:
a host system including at least one host processor and a basic input/output system (BIOS); and
an embedded controller (EC) including an EC processor;
wherein, in response to the information handling system receiving an instruction from a user to initiate a forced power off, the EC is configured to:
store diagnostic information indicating a state of the host system; and
upon a subsequent boot of the host system, transmit information to the BIOS indicating the forced power off.

### Claim 2 (depends on 1)

The information handling system of claim 1, wherein the instruction from the user includes a prolonged press on a power button of the information handling system.

### Claim 3 (depends on 1)

The information handling system of claim 1, wherein storing the diagnostic information includes accessing a memory of the host system via memory-mapped input/output (MMIO).

### Claim 4 (depends on 1)

The information handling system of claim 1, wherein, upon the subsequent boot of the host system, the BIOS is configured to execute a remediation procedure based on the diagnostic information.

### Claim 5 (depends on 4)

The information handling system of claim 4, wherein the remediation procedure is selected from the group consisting of performing a partial reset of a pre-boot environment of the host system, performing a memory diagnostic, replacing a driver, and replacing an operating system.

### Claim 6 (depends on 1)

The information handling system of claim 1, wherein the EC is configured to store the diagnostic information further in response to a crash of the host system.

### Claim 7

A method comprising:
an information handling system receiving an instruction from a user to initiate a forced power off;
in response to the instruction, an embedded controller (EC) of the information handling system storing diagnostic information indicating a state of a host system of the information handling system; and
upon a subsequent boot of the host system, the EC transmitting information to a BIOS of the information handling system indicating the forced power off.

### Claim 8 (depends on 7)

The method of claim 7, wherein the instruction from the user includes a prolonged press on a power button of the information handling system.

### Claim 9 (depends on 7)

The method of claim 7, wherein storing the diagnostic information includes accessing a memory of the host system via memory-mapped input/output (MMIO).

### Claim 10 (depends on 7)

The method of claim 7, wherein, upon the subsequent boot of the host system, the BIOS is configured to execute a remediation procedure based on the diagnostic information.

### Claim 11 (depends on 10)

The method of claim 10, wherein the remediation procedure is selected from the group consisting of performing a partial reset of a pre-boot environment of the host system, performing a memory diagnostic, replacing a driver, and replacing an operating system.

### Claim 12 (depends on 7)

The method of claim 7, wherein the EC is configured to store the diagnostic information further in response to a crash of the host system.

### Claim 13

An article of manufacture comprising a non-transitory, computer-readable medium having computer-executable code thereon that is executable by an information handling system for:
receiving an instruction from a user to initiate a forced power off;
in response to the instruction, an embedded controller (EC) of the information handling system storing diagnostic information indicating a state of a host system of the information handling system; and
upon a subsequent boot of the host system, the EC transmitting information to a BIOS of the information handling system indicating the forced power off.

### Claim 14 (depends on 13)

The article of claim 13, wherein the instruction from the user includes a prolonged press on a power button of the information handling system.

### Claim 15 (depends on 13)

The article of claim 13, wherein storing the diagnostic information includes accessing a memory of the host system via memory-mapped input/output (MMIO).

### Claim 16 (depends on 13)

The article of claim 13, wherein, upon the subsequent boot of the host system, the BIOS is configured to execute a remediation procedure based on the diagnostic information.

### Claim 17 (depends on 16)

The article of claim 16, wherein the remediation procedure is selected from the group consisting of performing a partial reset of a pre-boot environment of the host system, performing a memory diagnostic, replacing a driver, and replacing an operating system.

### Claim 18 (depends on 13)

The article of claim 13, wherein the EC is configured to store the diagnostic information further in response to a crash of the host system.
