Laptop won't turn on - what you can check before visiting the repair shop
Pressing the power button and getting no response is one of the most stressful laptop problems, especially when important files are on the drive. Before you visit our computer repair service in Warsaw, a few safe checks can save a trip or help us diagnose faster.
This guide explains what you can try at home, what you should not do, and when hardware diagnosis at the workshop is necessary.
Each pattern suggests a different cause. Note exactly what happens before you call us.
In our Warsaw workshop the most common causes of a dead laptop are:
Telling these apart requires test equipment - multimeter, lab PSU, RAM swap. That is workshop work, not home guesswork.
We measure voltages, test with a compatible charger, try known-good RAM, and inspect the DC jack under magnification. If the fan spins but the screen stays black, we test with an external monitor and check the LCD cable. You get a clear answer on cost and time before any repair starts.
If the laptop is under 5 years old, power-related fixes usually make economic sense. On very old machines we explain honestly when replacement is smarter than mainboard work.
