This guide is a practical, ordered fix for Pavilion 15 Laptop Overheating on Pavilion 15 running Windows. Start with the least destructive checks, then software repairs, and only then a backup-and-reset. Each numbered step includes a simple diagram so you can match what you see on screen.

Who this guide is for

• Primary device: Pavilion 15
• Software family: Windows
• Brand: HP

Editor notes before you start

• This guide is written for Pavilion 15 on Windows. Sister HP models are often similar, but menu labels can move after an update — use Settings search when a path differs.
• We keep these guides intentionally focused: fewer pages, clearer steps, and honest stop-points before unsafe hardware work.

What you will need

• 10–15 minutes without rushing
• Your device passcode / password

Before you start

• Save any open work on Pavilion 15 if the device is still responsive.
• If you have not backed up recently, start a quick cloud backup before deeper resets.
• Work through the steps in order; skip ahead only if a step clearly does not apply.

Symptoms

• The chassis becomes uncomfortably hot during light use or while idle.
• Apps close, frame rates drop, or the device shuts down to protect itself.
• Charging slows or pauses because the battery is too warm.

Common causes

• Startup programs overloading boot
• Failing or nearly full drive
• Malware or browser miners
• Dust-clogged cooling (laptops)

Step-by-step fix

1

Restart and note thermal state

Restart Pavilion 15 cleanly. Feel for unusual heat. Remove thick cases during testing. Close unused apps from the app switcher.

2

Free storage and curb background work

Open Storage settings and free 15–20 GB. Disable heavy Startup apps via undefined. Run Disk Cleanup / Storage Sense.

3

Install available updates

Open Check for OS and BIOS updates from the manufacturer, install patches, reboot, then check Optional updates for drivers.

4

Trim background drainers

Disable heavy startup/login items and pause large cloud syncs during the test window.

5

Deeper isolation before erase

Run a clean boot, check Device Manager for warning icons, and note whether the fault is immediate (often drivers/hardware) or after minutes (often heat or a background service).

6

Last resort: backup then reset

Back up files. Use OS recovery / reset options with “Keep my files” first. Only choose a full wipe if the fault survives. After reset, test clean before reinstalling every old app.

What success looks like

Opening apps and switching tasks on Pavilion 15 feels snappy again, without immediate thermal shutdowns.

Prevention tips

• Leave at least 10–20% free storage on Pavilion 15.
• Install OS updates within a week or two of release once early bugs settle.
• Stop DIY if you smell burning, see liquid damage indicators, or the chassis is swollen.

When to get professional help

Stop DIY if you smell burning, see liquid damage, notice a swollen battery, or if Pavilion 15 still fails after a clean backup-and-reset. Physical damage and board-level faults need professional service.
