Computer won't turn on in Montréal
“Won’t turn on” can describe several different failures: no lights or fan activity, power with a black screen, a logo that never reaches Windows, repeated restarts, or a laptop that works only with the charger connected. The first step is separating no-power, no-display and no-boot symptoms.
No power, no display or no boot?
A computer with absolutely no signs of power can have a charger, battery, power supply, charging-port or motherboard problem. A computer that lights up and spins fans but shows no image may instead have a display, RAM, graphics or board issue. If a logo appears but Windows never loads, storage or operating-system problems become more likely.
These categories overlap, so replacing a battery or reinstalling Windows before identifying which stage is failing can lead to unnecessary work. Simple observations such as indicator lights, beep codes, fan behaviour, external-monitor output and whether the charger is recognized can narrow the diagnosis.
What we check first
Depending on the device, testing may include the charger or desktop power supply, battery behaviour, charging port, memory seating, external display output, storage detection and basic motherboard symptoms. For a desktop, recent hardware changes are also important because a loose cable, RAM module or graphics card can prevent startup.
If the computer contains important data, tell us before any storage replacement or Windows work. A machine that does not boot can still have recoverable files even when the operating system will not start.
Repair path and related services
The next step depends on the failure found. A software boot problem may lead to Windows repair or installation, while a power or board fault may need hardware work. Laptop charging problems can also be separated between the adapter, battery, port and motherboard power circuit.

Frequently asked questions
My laptop has lights but the screen is black. Is that “no power”?
Not necessarily. Lights or fan activity suggest the computer is receiving some power, so display, RAM, graphics or motherboard faults may be more relevant.
Can a dead battery stop a laptop from turning on?
It can on some models, but a charger, port or board problem can look similar. The charging path should be checked.
Can my files still be recovered if Windows will not start?
Often yes, depending on the condition of the storage device. Avoid repeated risky repair attempts if the files are important.
