Laptop Not Charging? Find Out Why, Then Fix It
Plugged in but not charging, stuck at 0%, or only charging when the cable sits at an angle. We test the charger, battery and port in turn so you only pay for the part that actually failed.

A laptop that won't charge has one of four causes: the charger, the battery, the charging port, or a setting that deliberately stops charging. The first three look identical from the outside, which is why people end up buying a new charger they didn't need.
Try the free checks below first. If it still won't charge, we diagnose it for free, tell you which part failed and what it costs, and never order a part until you approve the price.
Why a Laptop Stops Charging
Roughly in order of how often each one turns out to be the cause.
A setting is stopping the charge
Lenovo Vantage's Conservation Mode, MyASUS Battery Health Charging, Dell's "Primarily AC use" and HP's battery care settings deliberately stop charging at around 60 to 80%. If it stops at the same number every time, check these first.
The charger has failed
Adapters and their cables fail far more often than laptops. A missing or flickering light on the charger, or a cable that's frayed near either end, points here.
USB-C charger too weak
A phone charger or a low-wattage USB-C adapter can't keep up with a laptop. Windows may say "slow charger", or the battery drains while plugged in.
Plugged in, not charging at 0%
Usually a worn-out battery that the laptop no longer trusts, or a battery that has dropped too low to wake. A battery reset sometimes revives it; otherwise it needs replacing.
Worn charging port
Charges only when the plug is held at an angle, or the light flickers when you move it. On many laptops the port is a separate part we can replace.
Swollen battery
A trackpad that's lifting, a case that no longer sits flat, or a bulge underneath. Stop charging it and message us: swollen batteries need replacing promptly.
Free Checks Before You Buy Anything
Try a different charger of the right wattage if you have one, and a different wall outlet. Look along the cable for kinks and fraying near both ends, and check that the plug sits firmly in the port.
Shut the laptop down fully, unplug it, and hold the power button for 30 seconds, then plug it back in. On Windows, the command powercfg /batteryreport saves a report that shows how much capacity the battery has left compared with when it was new.
If the battery stops at the same percentage every time, look in the maker's app (Lenovo Vantage, MyASUS, Dell Power Manager or HP's battery settings) for a charge limit before assuming anything is broken.
Which Charging Ports We Replace
On many laptops the charging port sits on a small separate board, or on a short cable (often called a DC jack harness) that plugs into the motherboard. Those are a straightforward replacement, quoted after a free inspection.
On others, including many thin and USB-C laptops, the port is soldered directly to the motherboard. We don't do board-level soldering, so if yours is soldered we'll tell you during the free diagnosis and explain your options honestly: the manufacturer's repair service, or whether the laptop is worth repairing at all. Either way we can recover your files.
From First Message to Fixed
Step 1: Tell us the symptoms
What the charging light does, what the battery percentage says, and the model number. A photo of the charger label helps.
Step 2: Free diagnosis
We test the charger, battery and port in turn and tell you exactly which one failed and what it costs.
Step 3: Repair and test
The failed part replaced, the battery calibrated, and charging tested before it comes back to you.
What a Charging Repair Costs

You approve the quote before we order anything. If the fault is just the charger or a setting, we'll tell you, and you won't pay for a repair you don't need. See full pricing.
Laptop Not Charging FAQs
Why is my laptop plugged in but not charging?
The most common causes are a charge-limit setting in the maker's app, a failed charger, a worn battery, or a loose charging port. Try another charger and check the battery settings first. If it still won't charge, the free diagnosis tells you which part has failed.
Why is my Lenovo laptop not charging?
On Lenovo laptops, check Conservation Mode in Lenovo Vantage first: it stops charging at around 60 to 80% on purpose. Many Lenovo models also have a small pinhole emergency reset on the underside. If neither helps, it's usually the battery, the adapter or the port.
Why is my HP laptop not charging?
Check the adapter light and the cable first, then HP's battery care settings. HP's built-in hardware diagnostics (press F2 as it starts) include a battery test. If the battery is worn, it will show in the battery report, and we can replace it from $40 labour plus the part.
My laptop battery is stuck at 0% and won't charge. Is it dead?
Often the battery is worn out, but not always. A full shutdown, a 30-second power-button hold and a few hours on a known-good charger sometimes bring it back. If it stays at 0%, a replacement battery usually fixes it.
Can you replace my laptop's charging port?
Yes, when the port is a separate part: a small board or a DC jack cable, which is common on many laptops. We don't solder ports that are built into the motherboard. We check which kind yours has during the free diagnosis, before you pay anything.
Is it safe to keep using a laptop that only charges at an angle?
It's best not to. A loose connection can arc and heat up, and wiggling the plug wears the port faster. Use it on battery until it's checked, and message us.
