What the service involves
Service details
The existing battery is checked for charge capacity, cycle behaviour and physical condition, and the charging path is tested at the adapter and the port. If the battery is the cause, a replacement of the correct type for your model is fitted and the machine is charged and discharged to confirm normal behaviour.
Swollen batteries are treated as urgent. A pack that has expanded puts pressure on the case, the touchpad and sometimes the board, and continuing to use the machine in that state is not advisable.
Why this service may be needed
Battery capacity falls gradually, so most people adjust to it without noticing — until the laptop can no longer be moved from the desk. Replacing the pack restores portability, and in the case of a swollen battery it also removes a genuine safety and hardware risk.

Frequently asked
Questions about battery replacement
Something not covered here? Call the counter or send a message on WhatsApp with your model number and the symptom.
How do I know whether my battery needs replacing or just recalibrating?
Capacity is measured against the battery's original rating and its charge cycles are checked. That distinguishes normal ageing from a battery that has actually failed.
What does "plugged in, not charging" mean?
It means the system sees the adapter but is not sending charge to the battery. The cause may be the battery, the adapter or the charging circuit, so all three are tested.
Is a swollen laptop battery dangerous?
A swollen pack should be taken seriously. Stop using the machine, avoid charging it, and bring it in — the expansion can damage the touchpad, the casing and the board underneath.
Can the battery be replaced on a laptop with a sealed body?
Most sealed models still have a replaceable internal pack; it is reached by removing the bottom cover rather than a external latch. Whether it can be done for your model is confirmed at the inspection.
Will replacing the battery make my laptop faster?
No. A new battery restores running time away from the mains. If the machine is slow, storage and memory are the things to look at instead.
