DETAILED DESCRIPTION

In some situations, a computing device may lose output functionality due to an error in a component. For example, a driver for a graphics card of a computing device may become corrupted during a boot up process. The computing device may not be able to output any graphical information using the graphics card, thus making troubleshooting the error challenging.

Examples described herein provide an approach to provide error information of a computing device using a storage device of the computing device. In an example, a computing device may include a power supply. The computing device may also include a storage device to receive power from the power supply during an error collection operation. The storage device may also receive power via radio waves from a client device during a diagnostic operation. The computing device may further include a controller to receive error information associated with the computing device and store the error information in the storage device during the error collection operation.

In another example, a computing device may include a power supply, an input device, a controller, and a storage device disposed below the input device. The storage device may receive power from the power supply. The storage device may also receive power via radio waves when the power supply is unavailable. The controller may, in response to detecting error information associated with the computing device, store the error information in the storage device.

In another example, a computing device may include a power supply, a storage device having an antenna, and a controller. The storage device may receive power from the power supply via a wired connection during an error collection operation. The storage device may also receive power wirelessly from an external device during a diagnostic operation. The controller may receive status information of a component of the computing device and store the status information in the storage device during the error collection operation. Thus, examples described herein may enable a computing device to provide error information to another device for diagnostic even if the computing device is not operational.

FIG. 1 illustrates a computing device 100 to provide error information associated with computing device 100 via a storage device, according to an example. Computing device 100 may be, a web-based server, a local area network server, a cloud-based server, a laptop computer, a desktop computer, an all-in-one system, a tablet computing device, a mobile phone, an electronic book reader, or any computing device suitable to store error information in a storage device.

Computing device 100 may include a processor 102, a power supply 104, a controller 106, a storage device 108, and a component 110. Processor 102 may control operations of computing device 100. Processor 102 may be a central processing unit (CPU), a semiconductor-based microprocessor, and/or other hardware devices suitable for retrieval and execution of instructions stored in a computer-readable storage medium.

In some examples, power supply 104 may be implemented as circuitry that converts alternating current to direct current. The direct current may be used to power the components of computing device 100.

Component 110 may be an entity that performs a particular function in computing device 100. Component 110 may be a hardware device, a set of processor executable instructions, or a combination thereof. In some examples, component 110 may be implemented as a basic input/output system (BIOS) of computing device 100. In some examples, component 110 may be implemented as an operating system (OS) of computing device 100.

As described in more detail below, controller 106 may be connected to component(s) of computing device 100, such as processor 102, component 110, etc. to monitor and/or receive error information of component(s) of computing device 100.

Storage device 108 may be a device where data/information is stored for retrieval. Storage device 108 may be implemented using non-volatile memory, such as solid-state memory. Storage device 108 may receive power from power supply 104 via a wired connection. In some examples, storage device 108 may be directed connected to power supply 104 to receive power. In some examples, storage device 108 may be indirectly connected to power supply 104 via controller 106 to receive power. That is, power supply 104 may provide power to controller 106. Controller 106 may in turn pass on or provide power to storage device 108. As described in more detail below, storage device 108 may include circuitry and components to receive power wirelessly via radio waves from another device that is different from computing device 100. Thus, storage device 108 may be able to provide data/information stored for retrieval even when computing device 100 is not operational and/or power supply 104 is unavailable.

During operation, controller 106 may perform an error collection operation. During the error collection operation, controller 106 may receive error information 112 associated with a component of computing device 100, such component 110. Controller 106 may store error information 112 in storage device 108. Component 110 may detect an error during operation and generate error information 112. Component 110 may transmit error information 112 to controller 106. In some examples, controller 106 may be connected to component 110 and may monitor the operation of component 110. Thus, controller 106 may detect an error during operation of component 110 and generate error information 112. Controller 106 may then store error information 112 in storage device 108. During the error collection operation, storage device 108 may receive power from power supply 104.

As described in more detail in FIGS. 2-5, the error may cause computing device 100 to become non-operational, such as not being able to turn on, not being able to boot into the operation system, not being able to output information for display, or power supply 104 malfunctioning (thus not being able to provide power to any component of computing device 100), etc. Another device may provide power to storage device 108 to retrieve error information 112. Error information 112 may be used to repair the error.
