Repair scenario

A laptop only charges at a particular cable angle

The charge indicator changes when the cable moves, while the laptop otherwise runs normally. Compare the adapter and cable, inspect the connector and assess the charging path. A replacement battery is not assumed to fix a mechanical connection fault.

Illustrative repair scenario, not a recorded TECHHELP customer job. The actual fault and repair options require assessment.

Repair questions and answers

Practical answers for the devices and faults covered on this page.

Can you repair a laptop that will not turn on?

Yes. TECHHELP checks charger, battery, power input, board condition and liquid damage symptoms before quoting.

My laptop screen is black but the keyboard lights up. What does that mean?

It may be a display panel, cable, backlight, graphics or motherboard fault. Diagnosis confirms the cause.

Can overheating damage a laptop?
