Creating a new power plan can help with battery life, power issues, fan noise, overheating etc.

Battery Reset, always step one when troubleshooting power issues.

BEFORE STARTING ANYTHING RESET YOUR BATTERY>POWER CYSCLE YOUR LAPTOP.

Most power issues may be cured reasonably easily. Unplug the laptop, unplug the cable from the charger, if it has a detachable cable (most do) and hold the power button on the laptop for thirty seconds.

Please be sure that you do a full thirty seconds, not a "fast count" as it were.

After that plug the laptop and cable back in, and do another full 30 second count holding the power button with the laptop plugged in, preferably in a different room to usual, directly into a wall socket and leave it charging overnight USING THE ORIGINAL CHARGER.

Especially on HP laptops this seems to help

Creating a "better" power plan

First search power plan in the windows search bar:


Select choose or edit a power plan.

Click Power options near the top of the window that opens:

Click create a new power plan, and then set the timings for sleep/hibernate etc as you like. DO NOT edit a power plan, create a new one.

Name the power plan as you like and follow the instructions, click next until the plan is created and "saved".

Once the plan is created, then go back to it/into it/edit power plan and select advanced options.

Find and change the majority of the advanced battery settings on the power plan to a higher percentage, at least ten percent for each.


In general we recommend over 10% (read 15%) for the low battery level, over 7% for the critical level9read 10%) and over 7% (read 10%) for the reserve level.

That should help with any long idle periods where work can be lost.

Fr fan noise, simply setting the fan settings (if available) to stop the fan maxing out, and/or setting the Processor power management to cap out at 95% or lower can help.

This can also help with overheating issues.

💬 Why Manufacturer Battery‑Life Claims Are (Mostly) Nonsense

Laptop battery‑life numbers look great on the box because they’re measured in conditions you will never use in real life. Manufacturers run their tests in ultra‑controlled, ultra‑optimised scenarios designed to squeeze out the biggest number possible — not to reflect how people actually work.

Here’s what they typically do:

1. Screen brightness set to “cave mode”

Manufacturers test at 30–50% brightness, sometimes even lower. In real life, students run at 70–100% because lecture halls, libraries, and classrooms are bright. Brightness is one of the biggest battery drains, so this alone inflates the numbers massively.

2. No real apps running

Battery tests often use:

  • A looping video

  • A lightweight browser script

  • Zero background apps

  • No antivirus scans

  • No Teams/Zoom

  • No OneDrive sync

  • No TTS or audio/recording software

  • No extensions

  • No multitasking

In other words: nothing like actual student usage.

3. Wi‑Fi and Bluetooth barely used

Some tests minimise network activity or use a local file instead of real web browsing. But real students are constantly:

  • Streaming

  • Syncing

  • Downloading

  • Using cloud storage

  • Running online tools

Network activity hits the battery hard.

4. Power‑saving modes forced on

Manufacturers often enable:

  • Battery saver

  • Low‑power CPU states

  • Reduced refresh rates

  • Aggressive sleep timers

These settings make the laptop feel sluggish — so nobody uses them.

5. Brand‑new battery, perfect conditions

Batteries degrade from day one. The advertised number is from a fresh, factory‑new cell in a cool, controlled lab. Real batteries often lose 10–20% capacity in the first year.

6. “Up to” is doing a LOT of heavy lifting

When a laptop says “Up to 12 hours”, it usually means:

  • 6–8 hours for normal use

  • 4–6 hours for academic use

  • 2–4 hours for Teams/Zoom calls

  • 1-2 Hours for TTS or recording/AI apps

Manufacturers know this — but “up to” lets them legally publish the best‑case scenario.

🎓 Why this matters for students

Students run the exact tasks that drain batteries fastest:

  • Teams/Zoom

  • Chrome with 10+tabs

  • OneDrive sync

  • PDF readers

  • Accessibility tools

  • Background apps

  • High brightness

So a laptop advertised as “12 hours” often delivers 4–6 hours in real academic conditions.
