Battery symptoms and what they usually mean
If your battery is swollen
A swollen battery is the one fault CompuTech treats as urgent in Calgary. A swelling lithium cell is the one laptop fault we treat as genuinely urgent, and it's more common than people realise on machines past about four years old.
How to tell
- The trackpad no longer clicks properly, or sits higher than the case around it
- The laptop rocks on a flat table instead of sitting still
- The lid doesn't close flush, or the base has a visible bulge
- On a Surface or tablet, the screen has started lifting away at one edge
What to do about it
Stop charging it. Shut it down rather than leaving it asleep. Take it off soft surfaces like beds and sofas. Don't press on the trackpad to see how bad it is, don't try to prise anything open, and don't attempt to puncture or deflate it. A damaged lithium cell can vent or ignite, and the pressure is what makes that more likely.
Then bring it in. We remove and replace it properly and dispose of the old cell the way it has to be disposed of, which isn't in household waste. Caught reasonably early this is a battery job. Left long enough, the swelling damages the trackpad, cracks the case, or on a glued device pushes the screen out, and then it's not a battery job any more.
When the battery is simply worn out
The ordinary case CompuTech sees: a battery that has simply done its miles. Every laptop battery loses capacity as it's used. It's chemistry, not a defect. A machine that used to give you seven hours and now gives you ninety minutes has a battery that has done its miles.
Modern batteries are rated in charge cycles rather than years, and a cycle is a full charge worth of use rather than a single plug-in. Two half-charges make one cycle. That's why a laptop that lives on a desk plugged in can still have a healthy battery after five years, while one carried everywhere can be finished in two.
We test before we sell you one
Windows and macOS both report the battery's design capacity, its current capacity and its cycle count, and that tells us plainly whether the battery is genuinely worn or whether something else is draining it. Sometimes the answer is a background process, a power setting, or a machine running hot enough to burn through charge. Replacing the battery in those cases changes nothing, and you would have paid for it.
Plugged in and not charging
This one has four possible causes and only one of them is the battery, which is exactly why the free diagnosis exists.
| Cause | How common | The fix |
|---|---|---|
| The charger or its cable | The most common of the four | A new charger, the cheapest outcome |
| The charging port or connector | Wears with years of plugging in | Port repair |
| The charging circuit on the board | Less common | A board repair, not a battery |
| The battery itself | Roughly one time in four | Battery replacement |
- The charger itself, including a cable that has failed inside the sleeve
- The charging port or connector, which loosens and wears with years of plugging in
- The charging circuit on the board, which is a repair, not a battery
- The battery, which has stopped accepting charge
A worn charger cable is the most common of the four and the cheapest to fix, so it's a poor outcome to have paid for a battery instead. We test the charger, the port and the battery separately and tell you which one it is.
About cheap batteries, and getting more life from a new one
CompuTech's view on cheap batteries, and how to get more life from a new one. There's a lot of very cheap laptop battery on the market and quite a bit of it's not worth having. Under-specified cells, missing protection circuitry and capacity claims that don't survive contact with reality. Fitting one of those into a machine you use daily is a false economy and occasionally a safety issue.
We fit batteries we're willing to stand behind, and if you've bought one yourself we'll tell you what we think of it before fitting it rather than after.
Making the new one last
- Heat is what ages a battery fastest, so keep vents clear and off duvets and cushions
- Living permanently at 100 percent is harder on a cell than cycling in the middle of the range
- Many laptops now offer a charge limit setting for machines that mostly stay plugged in, which is worth switching on
- Deep discharges to zero repeatedly do more harm than topping up during the day
- Full monthly calibration cycles are a myth left over from older battery chemistry
No surprises. Ever.
You get a clear, flat-rate quote before any work begins. If we can't fix it, you don't pay the repair fee. Simple as that.
Every job is different, so we look first and quote you directly. No surprises, and nothing happens until you've said go.
Three steps to a working battery
“I needed a battery replacement on my 6 year old Apple Macbook Pro. Mohammed did an excellent job, provided outstanding advice, and all at a very reasonable price. I highly recommend his services.”
“Within 40 minutes of my first phone call, Mohammed had my laptop in his hands and was already taking it apart while explaining the issue and repair process to me in detail. He diagnosed the problem quickly and efficiently, and his expertise was obvious throughout the entire experience.”
“I could not be happier with my repair service and the way my laptop is working! He offered extra advice on how to set up my home office, as well as how to make me more efficient utilizing my laptop! Very happy girl over here!! Thank you Moe!! 10 out of 10 recommend!!!”
Questions, answered
Almost certainly. A swelling battery sits directly under the trackpad on most laptops and pushes it up. Stop charging the machine, don't press on the trackpad, and bring it in.
Yes, treat it that way. A swollen lithium cell can vent or catch fire, and pressure and heat make that more likely. Don't puncture it, don't leave it charging unattended, and don't use it on a bed or sofa.
We would rather you didn't. Prising a swollen cell out of a tight case is exactly how they get punctured, and most modern batteries are glued in as well as screwed. Bring it to us and it costs you very little more than the part.
Not in household waste and not in the recycling bin. We take the old one when we fit the new one and dispose of it properly, which is the easiest answer for you.
Batteries are rated in charge cycles rather than years, and a cycle is a full charge worth of use rather than one plug-in. A machine that mostly lives on a desk can be fine after five years. One carried everywhere daily can be finished in two.
Windows and macOS both report design capacity, current capacity and cycle count. We read those in the free check, because if the battery is healthy and something else is eating the charge, a new battery changes nothing.
Only one time in four, roughly. It can also be the charger, the charging port, or the charging circuit on the board. A failed charger cable is the most common cause and the cheapest to fix, so it's worth testing before replacing anything.
That's a battery that has stopped holding charge at all. It's usually straightforward to replace, and worth doing on any machine you want to carry anywhere.
A worn cell that can't maintain voltage under load. The percentage reading is based on an assumption about capacity the battery no longer has, so the machine drops out without warning.
Most are same-day when we have the part. Glued batteries in thin machines and Surface devices take longer because they need heat and patience to remove safely.
Yes, across MacBook Air and MacBook Pro. They are adhered rather than clipped in, so it's careful work, and swollen ones are common on older models.
You can, and we'll tell you what we think of it before fitting rather than after. A lot of very cheap cells are under-specified or missing protection circuitry, and that's a poor trade in something that lives on your lap.
Keep it cool, keep the vents clear, and if your laptop offers a charge limit setting and mostly stays plugged in, turn it on. Heat and sitting permanently at full charge are what age a cell fastest.
No. That advice is left over from an older battery chemistry and it does modern cells no favours. Regular deep discharges shorten their life rather than extending it.
It depends on the model, because batteries vary a lot between machines. You get one flat quote after the free check, before anything is done.
Yes, in-home across Calgary and the nearby towns for most models, or drop it at 303 Wentworth Row SW, open seven days. Glued batteries are bench work.
