First determine whether the failure affects one computer or a shared service. If several employees cannot open the same application, the problem may be an account, network, or vendor outage. Repeatedly changing settings on individual laptops can make the situation harder to diagnose.
Make the immediate situation safe
Stop using a device with smoke, a burning smell, liquid damage, or a visibly swollen battery. Do not keep trying to power it on. For suspected malicious activity, follow your organization’s incident process and contact the responsible IT person before attempting cleanup.
For an ordinary unresponsive application, note what is open and whether work has been saved. A forced power-off can discard unsaved changes. Record the error or screen state before restarting when practical.
Check the scope
Ask whether other users are affected, whether another application works, and whether the issue changes on an approved wired or wireless connection. Check simple physical connections without dismantling the device. Note whether the power adapter and dock belong to this computer.
Avoid downloading unsolicited “repair” utilities or accepting support from a pop-up. Use a known support contact. Give that person the asset details, start time, last successful task, and any recent update or hardware change.
Keep the employee productive
Move urgent work to an approved spare device when available. Use normal business sign-in and storage; do not copy confidential files to a personal account as a shortcut. Record any temporary workaround so it can be removed or reviewed later.
Close the incident with evidence
The computer turning on is only the first check. Repeat the failed task, test needed peripherals, and confirm current work is available. Record what was fixed and whether further work is scheduled.
The laptop repair checklist helps prepare a repair handoff. For a problem affecting several devices, see network troubleshooting.
