A swollen laptop battery should not be ignored.
If the trackpad is lifting, the case is bulging or the laptop smells hot, stop charging it and arrange inspection. Continuing to use a swollen lithium-ion battery can damage the chassis and increase fire risk.

- Do not keep charging overnight
- Keep it away from heat

Why people book this
Computer repair should start with a proper diagnosis, not a guess.
Verge Tech repairs laptops, desktops, Macs and gaming PCs with a fixed quote before work starts. The priority is to protect your data, identify the fault, explain the options and avoid spending money on a device that is past economical repair.
Battery drains very quickly
Ageing batteries lose capacity over time. We check the cycle count and health report before recommending replacement.
Laptop says plugged in, not charging
This can be battery, charger, USB-C charging, DC jack or motherboard related. We test the charging route before changing parts.
Swollen or lifting laptop case
A swollen battery needs careful handling. We remove it safely, inspect for pressure damage and advise on the correct replacement.

Service detail
Repair, explain, prevent repeat faults.
Many repair jobs reveal a deeper issue: failing storage, poor backup, overheating, malware or old hardware. We fix the visible fault and leave practical notes so the same issue is less likely to return.
Diagnosis before parts
We check the device, confirm the likely fault and explain whether repair, upgrade or replacement is the sensible route.
Data treated carefully
Any repair that risks data starts with a backup or recovery assessment. We do not copy or inspect files beyond what the job requires.
Fixed repair route
You approve the repair and parts before work starts. No hourly creep and no surprise bills at handover.
Who this is for
Built for real users.
If you recognise yourself in any of these, we've done the work before.
Before you book
Battery faults can look similar to charger and charging-port faults.
A proper diagnosis prevents paying for a new battery when the adapter, USB-C port, DC jack or charging circuit is the real cause.
Battery health report
Windows and macOS battery reports help show design capacity, current capacity and whether replacement is likely.
Charger test
We check whether the power adapter delivers the correct output and whether the laptop recognises it consistently.
Charging port check
Loose, hot or intermittent charging ports are handled through the charging-port repair route, not a battery swap.
Part match
Battery shape, connector, voltage and model code must match. We confirm this before fitting.
FAQs
Questions people ask before booking.
How do I know if my laptop battery needs replacing?
Common signs include short battery life, sudden shutdowns, a service battery warning, charging stuck at a low percentage, or swelling around the trackpad or keyboard area. We confirm with a battery health and charging check.
Can you replace the battery the same day?
Same-day fitting is possible when the correct battery is already in stock. Less common models need the part ordered first, so we confirm the model before promising a turnaround.
Will my files be affected by a battery replacement?
A battery replacement should not affect your files. If we spot signs of drive failure or the laptop is unstable, we will tell you before doing anything that could put data at risk.
Do you replace MacBook batteries?
Yes, we handle MacBook Air and MacBook Pro battery faults. Some models are more involved because the battery is bonded into the top case, so we quote based on the exact model.
What should I do with a swollen laptop battery?
Stop charging it, shut the laptop down if safe, keep it away from heat and do not press the case back into shape. Book an inspection so the battery can be removed and recycled safely.
