Laptop battery not charging
Is your laptop not turning on? It is a common misunderstanding that a laptop does not turn on because the battery is not charging. While this may be true for mobiles, this is not the case with laptops. All laptops can work normally without the battery while on direct power supply from the laptop charger
When a laptop does not turn on, the motherboard may have died.
In this case we do a complete disassembly of your laptop. Your motherboard is then placed under a scope. We check your board for faulty ICs using a schematic chart and schematic diagram.
We check for voltage connectivity and link of the ICs
There are four main reasons why your laptop won’t turn on.
