A laptop battery that will not charge does not automatically mean you need a new battery. The problem can come from the wall outlet, charger, charging port, power settings, heat, outdated software, or a battery that has simply reached the end of its useful life.

The safest approach is to start with the easy checks before buying replacement parts. Below are seven things I would try first, starting with the power connection and working toward battery diagnostics. If the charger turns out to be the problem, I’ll also cover two affordable replacement options and explain who each one makes sense for.
1. Check the Wall Outlet and Power Connection
Start with the simplest possibility: your laptop may not actually be receiving power.
Unplug the charger from both the laptop and the wall. Wait a few seconds, reconnect everything firmly, and see whether the charging indicator appears.
Then test the wall outlet with another device, such as a phone charger or lamp. You can also plug the laptop charger into a different outlet to rule out a problem with a power strip, surge protector, or wall socket.
Dell recommends checking the outlet early in the troubleshooting process because a dead or unreliable power source can look exactly like a laptop charging problem.
If your charger has an indicator light, check whether it stays on. A light that goes out when you connect the laptop can point to an adapter, cable, port, or internal electrical problem.
Avoid repeatedly forcing the plug into the laptop if the connection feels loose or damaged.
2. Inspect the Charger, Cable, and Charging Port
Next, look closely at the entire charging setup.
Check the cable for:
- Frayed insulation
- Exposed wires
- Sharp bends
- Crushed sections
- Bent connector pins
- Heat damage
- A loose connector
Also inspect the laptop’s charging port. Dust, lint, or physical damage can prevent the plug from making a proper connection. Dell specifically recommends checking both the charger and charging port when diagnosing a battery that will not charge.
If your laptop charges over USB-C and has more than one USB-C port, make sure you are using a port that actually supports charging. Some laptops have several USB-C connectors but only certain ones accept power.
The charger also needs to provide the correct amount of power. An adapter with insufficient wattage may be able to keep a laptop running while still failing to charge the battery properly. Dell notes that an underpowered adapter can cause a laptop to show a plugged-in state without increasing the battery percentage.
This is why I would not buy a replacement charger based only on whether the connector physically fits.
Voltage, wattage, connector type, polarity, and manufacturer requirements all matter.
3. Restart the Laptop and Perform a Power Reset
A temporary power-management problem can sometimes interfere with charging.
Start with an ordinary restart.
If nothing changes, shut down the laptop completely. Disconnect the charger and any USB devices, external drives, docks, or accessories.
For laptops with a removable battery, you can remove the battery if the manufacturer’s instructions allow it. Hold the power button for around 15 seconds, then reconnect the battery and charger.
On many newer laptops with sealed batteries, you should follow the manufacturer’s specific reset procedure rather than opening the computer.
HP includes a hard reset as one of its recommended troubleshooting steps when a laptop battery is not charging.
Mac owners have a slightly different process. On Apple silicon Macs, Apple recommends restarting the computer when troubleshooting power-management issues. Some older Intel Macs may benefit from resetting the System Management Controller, or SMC.
A restart or power reset will not repair a physically damaged battery, but it is quick enough that I would try it before changing drivers or buying hardware.
4. Make Sure Charging Is Not Being Limited on Purpose
A laptop that stops charging at 80 percent may actually be working correctly.
Modern laptops often include battery-health features that intentionally limit charging to reduce the amount of time the battery spends at a very high charge level.
For example, some Dell laptops offer battery modes such as Adaptive, Primarily AC Use, and Custom charging thresholds. A custom setting can intentionally stop charging before the battery reaches 100 percent.
Apple also uses battery health features that may delay or stop charging before 100 percent in order to reduce battery aging.
So before assuming something is broken, ask yourself what the laptop is actually doing.
If it charges normally to 80 percent and then stops, check the battery-management software or BIOS settings.
If it stays at 3 percent while plugged in and continues dropping, that is a very different problem.
I would avoid disabling battery-health features permanently just because you want to see 100 percent every day. They exist to help reduce long-term battery wear.
5. Let the Laptop Cool Down
Heat can interfere with charging.
If the laptop feels unusually hot, shut down demanding applications and move the computer to a cooler, well-ventilated location.
Apple says its Mac laptops are designed to work best in ambient temperatures between 50°F and 95°F, or 10°C and 35°C, and recommends letting an overheated Mac cool down when it is having charging problems.
Heat can come from several places:
- Gaming
- Video editing
- Rendering
- Heavy multitasking
- Blocked cooling vents
- Using the laptop on a bed or blanket
- A hot car or room
- Charging while running demanding software
There is another possibility too. Your laptop may technically be charging, but the computer is using power almost as quickly as the charger can provide it.
Apple notes that demanding apps and connected devices can sometimes consume more power than the power source supplies.
Close demanding software, disconnect unnecessary accessories, and give the laptop some time.
If the battery begins charging normally after the computer cools down or the workload drops, you have a much better idea of what was happening.
6. Update Battery Drivers, BIOS, and System Software
If the physical connection looks fine, software is the next place I would look.
Laptop charging is controlled by more than the battery itself. The operating system, firmware, BIOS, charging controller, and device drivers all need to communicate properly.
Windows laptops may benefit from installing current BIOS and driver updates from the manufacturer’s support page. Dell lists outdated BIOS and drivers among the possible causes of charging problems.
You can also try reinstalling the Windows battery driver.
Open Device Manager, expand Batteries, and look for entries such as:
- Microsoft AC Adapter
- Microsoft ACPI-Compliant Control Method Battery
On systems where this troubleshooting step is appropriate, uninstalling those entries and restarting Windows allows the operating system to detect and reinstall them. Dell documents this approach as one step for a battery that is detected but not charging.
I would still update the laptop through the manufacturer’s official support tools whenever possible rather than downloading random battery drivers from third-party websites.
Mac owners should check for macOS updates as well. Apple notes that software and firmware updates can sometimes improve communication between the Mac and its power adapter.
7. Check the Battery’s Health
If the charger works, the laptop recognizes it, and the battery still refuses to charge properly, the battery itself may be worn out.
Rechargeable laptop batteries are consumable parts. They gradually lose capacity as they age and go through charge cycles.
On Windows 11, you can generate a detailed battery report using Command Prompt.
Open Command Prompt as administrator and enter:
powercfg /batteryreport
Windows will create an HTML report showing information such as the installed battery, recent usage, battery usage, and estimated capacity. Microsoft recommends the battery report when you want a closer look at battery condition and performance.
Many manufacturers also provide their own diagnostic tools. HP Support Assistant, for example, includes a Battery Test that can identify battery failures.
Dell laptops can display battery health and AC adapter status in the BIOS on supported models.
The important question is whether the laptop has a charging problem or simply an old battery.
If the battery health is poor and the laptop works normally while connected to the charger, replacing the battery may make more sense than replacing the adapter.
Stop Using the Laptop if the Battery Is Swollen
There is one battery problem I would not troubleshoot by repeatedly charging and restarting the laptop.
If the case is separating, the trackpad is lifting, the keyboard is bulging, or the laptop no longer sits flat, the battery may be swollen.
Microsoft advises stopping use of a device if the battery expands beyond its normal enclosure. Do not press on, puncture, bend, or attempt to flatten a swollen battery.
At that point, disconnect the laptop from power and arrange proper repair or battery replacement.
How to Tell Whether the Charger Is the Real Problem
By now, you should have a much better idea of what is happening.
A replacement charger becomes more reasonable when:
- The existing cable is visibly damaged.
- The plug only works at a certain angle.
- The adapter is no longer recognized by the laptop.
- The charger gets unusually hot or cuts in and out.
- A known-good compatible charger works normally.
- The original charger has been lost.
- The adapter provides less wattage than your laptop requires.
Dell, for example, recommends checking AC adapter recognition and wattage when troubleshooting a battery that will not charge.
If the battery itself has failed, buying another charger will not solve the problem.
But if your testing points clearly toward the power adapter, replacement becomes the natural next step.
The most important rule is compatibility. Never assume that a charger is safe simply because the plug goes into the port.

HP 65W/45W Smart Blue Tip Charger: Best for Compatible HP Laptops
If you have a supported HP laptop that uses the familiar blue-tip barrel connector, the Charger Compatible with HP Laptop Computer 65W 45W Smart Blue Tip Power Adapter is the more straightforward of these two options.
The adapter is rated for up to 65W with a 19.5V output and a 4.5 x 3.0mm blue-tip connector. It is also listed as compatible with certain HP systems that originally use 45W adapters.
That makes it useful if you know your HP laptop requires this exact style of Smart AC adapter.
The keyword there is know.
HP has produced many laptop models with different charging requirements, including barrel connectors and USB-C charging. Even two HP laptops that look similar may not accept the same adapter.
Check the model number on the bottom of your laptop or look up the original HP adapter specifications before ordering. Match the connector, required voltage, and wattage rather than relying only on a long compatibility list.
Based on the Amazon details you provided, this charger has a 4.6 out of 5 rating from around 10,200 reviews and was listed at about $9.90. That is inexpensive enough to make sense as a replacement for a damaged adapter or even as a spare for a compatible HP laptop.
I would choose it over a universal charger when I already knew I had the correct HP blue-tip system. A dedicated adapter gives you fewer variables to think about.
But that does not help much if you have several laptops from different manufacturers or you are unsure which connector you will need in the future.
That is where a multi-tip adapter becomes more appealing.

XOUBZ 90W Universal Laptop Charger: Best for Multiple Laptop Brands
The XOUBZ 90W Universal Laptop Charger takes a different approach by including multiple interchangeable tips.
It is rated for up to 90W and includes 16 connector tips intended for a range of laptop brands, including HP, Lenovo, Dell, Acer, Asus, Toshiba, and others. Product information for this model lists several output voltages between 15V and 20V, with up to 90W available.
The attraction is obvious if you have several older laptops around the house.
Instead of keeping a separate power brick for each one, a universal adapter may be able to cover multiple compatible systems.
It can also be useful as a backup charger when traveling, particularly if you regularly work with different laptops.
I would be more cautious with a universal charger than with a model-specific adapter, though.
Before connecting it, confirm:
- Your laptop is listed as compatible.
- The correct physical tip is included.
- The required voltage matches.
- The adapter can provide enough wattage.
- The connector polarity is correct.
- Your laptop does not require a proprietary USB-C Power Delivery setup instead.
The fact that a tip fits does not prove that the electrical specifications are correct.
Based on the Amazon information you supplied, the XOUBZ charger had a 4.4 out of 5 rating from roughly 788 reviews and was listed at around $14.99.
For that price, the flexibility is appealing. I would choose it mainly for someone who has multiple compatible laptops or wants a general-purpose spare rather than someone replacing a charger for one specific HP system.
What to Check Before Buying Any Replacement Laptop Charger
This is one purchase where I would slow down and read the label.
Match the voltage
The replacement adapter should meet the voltage requirements specified for your laptop.
Do not assume a higher number is better.
Make sure the wattage is sufficient
A laptop that expects a 90W adapter may not charge correctly from a 45W adapter.
As Dell explains, insufficient charger wattage can result in the laptop running from AC power while the battery fails to charge normally.
Check the connector carefully
Barrel connectors can look almost identical while having different inner and outer dimensions.
USB-C is not automatically universal either. Both the charger and laptop need to support the appropriate charging standard and power level.
Look up your exact laptop model
Do not rely on a listing that simply says “compatible with HP” or “compatible with Dell.”
Find the complete model number and compare it against the charger specifications.
Replace damaged chargers instead of repairing them with tape
A little electrical tape around a cosmetic scuff is one thing. A cable with exposed conductors, severe heat damage, or a loose plug is another.
If the power adapter is physically damaged, replacing it is safer than trying to keep it alive.
Final Thoughts
If your laptop battery is not charging, start with the power source before blaming the battery.
Test the outlet, inspect the charger and charging port, restart the laptop, check whether a battery-health setting is intentionally limiting charging, let the machine cool down, update its software and drivers, and finally check the battery’s actual health.
Those seven steps should tell you much more than simply seeing “plugged in, not charging” on the screen.
If the battery health is poor, the battery itself may need replacement. If the battery is swollen, stop using the laptop and arrange proper service.
If your troubleshooting points toward the charger instead, the choice between these two replacements is fairly clear.
The HP 65W/45W Smart Blue Tip Charger makes more sense if you have a compatible HP laptop and want a simple, inexpensive dedicated replacement.
The XOUBZ 90W Universal Laptop Charger is the better fit if you need more connector options for several compatible laptop brands.
Whichever route you take, match the charger’s electrical specifications to your exact laptop first. A good replacement charger is not simply one that plugs in. It is one designed to provide the power your laptop actually expects.
