The Laptop With a Belly: A Quarterly Battery Walkround for Small Offices
A laptop should sit flat on a desk. If it rocks when you type, or the trackpad sits proud of the palm rest, that is not a design quirk. It is often a battery with nowhere to put its gas.
Lithium-ion cells swell as they age, as they are exposed to heat, or when they develop a fault. The casing becomes the pressure vessel. In a small office, that matters because the devices most likely to be affected are also the ones nobody thinks about: the spare laptop in the cupboard, the hot-desk machine that is always plugged in, the tablet by reception showing a slideshow, the old machine kept “just in case”.
Why this belongs on the office calendar
A battery check is not just an IT chore. It is a facilities check with an insurance angle. Most swollen batteries do not burst into flames, but the risk is real enough that you should not ignore a device that is visibly changing shape. A bulging case can also crack screens, distort keyboards, make trackpads unusable, and turn a cheap battery replacement into a much bigger repair bill.
For a UK small business, the practical response is not to buy specialist equipment. It is to build a short, repeatable walkround into the quarter. Fifteen minutes is enough to find the obvious problems and get them off desks before they become someone else’s emergency.
Where swollen batteries hide
Start with the devices that live in the building every day. Then check the ones that get forgotten.
- Main desk laptops, especially those left on charge all day.
- Hot-desk and meeting-room machines that are shared and rarely inspected.
- Loan laptops and spare machines in cupboards.
- Reception tablets, signage tablets, and any iPad used as a permanent display.
- Old laptops kept for a former employee, a legacy application, or “just in case”.
- Devices that run warm, sit on soft furnishings, or are charged with a non-standard adapter.
You are not trying to diagnose the battery chemistry. You are looking for change. A laptop that used to sit flat and now rocks is telling you something.
What to look for
A swollen battery often shows up in the chassis before it shows up anywhere else.
- The laptop rocks on a flat desk when you press a corner.
- The trackpad is lifted, stiff, or sitting higher than the palm rest.
- There is a gap between the top and bottom case that was not there before.
- The keyboard area bulges or the keys feel uneven.
- The screen does not close flush.
- The bottom case is bowed or the rubber feet no longer sit flat.
- The device is unusually hot when idle and not charging.
- There is a sweet chemical smell, though you should not rely on smell alone.
Do not press hard on a suspect casing and do not open the device to look inside. A swollen cell is under pressure. Gentleness is the point.
The 15-minute sweep
Pick a route through the office and a person to walk it. The same person does not have to do it every time, but the check should have an owner.
- Walk the route: desks, meeting rooms, cupboards, reception.
- For each device, unplug the charger if it is safe to do so, then look along the sides and underneath.
- Place the device on a flat desk and press a corner gently. Does it rock?
- Open and close the lid. Does it sit flush?
- Note the asset tag, location, symptom, and date in a simple spreadsheet.
- Mark any suspect device with tape and a clear label: do not use, do not charge.
That is it. You are not repairing anything. You are finding the devices that need to leave the desk.
If you find a swollen battery
Stop using the device. Unplug it and do not charge it. If the device is hot, hissing, smoking, or visibly damaged, do not handle it. Evacuate the immediate area and call 999. A swollen battery is a fire risk; a hissing or smoking one is an emergency.
If the device is cool and stable, isolate it. Move it to a cool, dry place away from paper, curtains, soft furnishings, and anything else that burns. A metal cabinet or a safe outdoor location is better than a desk drawer. Do not put it in a normal bin. Do not puncture it, compress it, or put it in water. Do not try to remove the battery yourself unless you are trained and equipped to do so.
In the UK, disposal needs to go through a proper route. That means a household waste recycling centre that accepts batteries, a retailer takeback scheme, or a licensed business waste contractor. For a business, keep the paperwork. Do not quietly slip it into the office general waste or the ordinary recycling bin.
Make it stick
Put the battery walkround in the calendar every quarter. Pair it with another recurring office task, such as checking fire extinguishers or testing the alarm, so it does not rely on memory. Add it to the checklist when a laptop comes back from a leaver, and check loan devices before they go out again.
It also helps to review charging habits. A laptop that lives on a soft cushion, under a pile of paper, or permanently plugged in will run hotter than one that gets some airflow. You do not need to turn battery care into a policy document. A few sensible habits and a quarterly look are enough.
A 15-minute walkround will not catch every failing battery. It will catch the ones already telling you something. For a small office, that is a very good return on a calendar reminder.
