Bisconti Computers badge: over 30 years of laptop battery and computer repair in Rockford, IL

Laptop Battery Replacement from a Local Rockford Shop

Laptop batteries wear out with age and use. When yours no longer makes it through a meeting or a class, a new battery can give a good laptop a lot more life for far less than the cost of a new computer.

At Bisconti Computers, battery replacement is done by our own technicians at 3065 N Perryville Rd in Rockford. We don’t ship your laptop away, and you can talk directly with the person working on it.

Bring your laptop and charger, or check in online. We’ll test the battery, the charger and the charging port, confirm what’s really causing the problem, and explain your options before any work begins.

Does Your Laptop Need a New Battery?

Battery Drains Fast

A charge that used to last hours now lasts minutes. That’s the most common sign of a worn battery.

Shuts Off Before It Hits Zero

A laptop that suddenly shuts off at 20 or 30 percent, or only runs while plugged in, often has a battery that can no longer hold its charge.

Swollen Battery

A bulging case, a lifting touchpad or a laptop that no longer sits flat can mean the battery is swelling. Stop using the laptop and bring it in right away.

Won’t Charge at All

If the battery light never comes on, the problem could be the battery, the charger or the charging port. We test each one before replacing anything.

Battery Warnings in Windows

A “consider replacing your battery” message or a battery that shows as not detected is a good reason to have it checked.

Built-In Batteries

Many newer laptops have batteries inside the case instead of a removable pack. We open the laptop and replace them for you.

Charger has to be held at an angle to work? That’s often a loose charging port, not the battery. See our laptop repair in Rockford page.

Should I Replace the Battery or the Whole Laptop?

If your laptop runs well when plugged in, a new battery is usually the better value. It keeps a working computer in service and saves you the time of setting up a new one. On a very old laptop, or one with other problems, a new computer may make more sense, and we’ll tell you honestly which way we’d go.

A swollen battery is a different story. Swelling puts pressure on the case, the touchpad and the screen, so the battery should be replaced right away, whatever you decide about the laptop.

How Laptop Battery Replacement Works

Walk in or check in online. Bring your laptop and charger during business hours. No appointment is needed.
We test the power system. A technician checks the battery, charger and charging port, then gives you an honest quote.
You approve the repair. Nothing is replaced without your approval.
We install the new battery. Many parts are on hand, and some batteries need to be ordered for your model; we’ll tell you if yours does. Some battery replacements are done the same day. Repairs carry a warranty of 30 days to 1 year, depending on the repair, under the Bisconti Service Guarantee.

How Much Does Laptop Battery Replacement Cost?

Diagnostics start at $59. Battery prices depend on your laptop’s exact model and whether the battery is removable or built into the case, so we don’t post one-size-fits-all prices.

Honest quote first. Every repair starts with a diagnostic so we can find the real cause. The diagnostic fee is not applied to the cost of the repair. If you decide to replace your laptop with a computer bought through Bisconti instead, we credit the diagnostic fee toward that new computer.
No surprise costs. You hear the price before any work begins, and nothing is replaced until you approve it.
Warranty included. 30 days to 1 year, depending on the repair.

Batteries for Dell, HP, Lenovo, ASUS, Acer and More

We replace batteries in Windows laptops from Dell, HP, Lenovo, ASUS, Acer and other brands. Your laptop is worked on by experienced, certified techs. MacBook battery? See our Mac repair in Rockford page.

Laptop Battery Replacement FAQ

How do I know my laptop battery needs replacing?

Common signs are a charge that runs down fast, sudden shutdowns before the battery reads empty, a battery warning in Windows, or a case or touchpad that has started to bulge.

How much does a laptop battery replacement cost?

It depends on your model and the type of battery, so we quote after testing your laptop and before any work begins. The diagnostic fee isn’t applied to the repair, but if you replace your laptop with a computer bought through us, we credit it toward the new one.

Is a swollen battery dangerous?

A swollen battery should be taken seriously. Stop using the laptop, don’t charge it and don’t press on the bulge. Bring it in so we can replace the battery.

How long does a battery replacement take?

It varies. Some battery replacements are done the same day. Many parts are on hand, but some batteries need to be ordered for your model, and we’ll let you know if yours does.

Is it the battery, the charger or the charging port?

It can be any of the three, which is why we test all of them first. A plug that only works at an angle usually points to the charging port.

Do I need an appointment?

No. Walk-ins are welcome Monday to Friday 9 AM to 5 PM and Saturday 9 AM to 2 PM. Please bring your charger.
