Common symptoms
No lights, no fan, no boot, charger light goes off, the power button does nothing, battery not detected, or the laptop died suddenly after working normally.
A completely dead laptop is often a motherboard power fault, not automatically a reason to replace the whole laptop.
BitSupport checks the charger input, DC jack path, shorted rails, MOSFETs, standby power and common board-level failure points before quoting. WhatsApp the model, town and what happens when you plug in the charger.
If another shop has said “motherboard replacement”, it is still worth asking before you spend on a full board. Some dead laptops can be diagnosed at board level, quoted, and repaired where the fault is suitable.
