Laptop Battery Repair Service
Batteries lose capacity with age. If your laptop drains quickly, shuts down unexpectedly or the casing has begun to swell, the cell needs replacing. A swollen battery is a safety risk and should be dealt with promptly. TechFix fits quality replacement cells in Faisalabad and verifies charging behaviour before handover.
Signs you need this repair
- Charge dropping fast, or the device shutting down well above 0%
- Case or trackpad lifting — a swollen cell pushing from underneath
- Device only runs while plugged in
- Heat around the base during normal use
What causes it
Lithium cells lose usable capacity with every charge cycle, and heat accelerates it. A swollen battery is a safety matter, not a performance one — stop using the device and bring it in.
What the repair involves
- 01Battery health and charge-cycle count read before anything is opened
- 02Charging circuit tested, because a bad charging IC mimics a dead battery
- 03Old cell removed with adhesive solvent rather than levered out
- 04New cell fitted, calibrated and load-tested
What affects the price
The cell itself, plus how much disassembly the model needs. Some laptops take ten minutes; some MacBooks require the whole top case out.
Before you bring it in
Do not keep charging a swollen battery. Power the device down and bring it in — swelling gets worse, and a punctured cell is a fire risk.
