The situation when the laptop stops turning on always causes stress. You press the power button and nothing happens: no screen backlight, no fan sound, no familiar boot logo. Sometimes the indicator flashes, sometimes there are no signs of life at all. At such a moment, it is difficult to understand whether the problem is serious or the reason may be quite simple. Service Wizards https://pctitanfix.lv They encounter similar requests every day and identify several typical reasons why the laptop refuses to start.
The first and most common reason is a faulty charger. The power cable may break, the adapter may fail, and the plug may become loose. Externally, the unit may look normal, but it does not supply the required voltage. It is difficult to check this without equipment, especially if the indicators on the laptop do not light up. In such cases, the service first tests the power supply and, if necessary, offers a replacement.
The second reason is a completely failed battery. If the battery has not been changed for a long time, it may not just hold a bad charge, but even block the laptop from starting. Sometimes the device starts only at a certain cable position, sometimes it does not respond at all. It is important to understand that prolonged operation with a dead battery can eventually damage the power supply circuit.
The third common problem is a BIOS or system settings failure. After an unsuccessful update, a power surge, or an incorrect shutdown, the laptop may stop displaying the image, although the system inside seems to be trying to start. In practice, this is manifested by a black screen and a lack of reaction to the keys. In this case, professional diagnostics and, possibly, flashing are needed.
The fourth reason is overheating. If the laptop had previously made a lot of noise, heated up and turned off under load, then at some point the protection could work so that the device stopped turning on altogether. Dried thermal paste, dust-clogged radiators and non-working coolers not only lead to overheating, but also damage the batteries and the motherboard over time.
The fifth reason is faulty RAM. Sometimes it is enough for one RAM module to fail so that the laptop stops booting. The indicators may blink and the fans may start, but there will be no image on the screen. It is impossible to understand this without testing and disassembly, and attempts to remove the slats on their own often end up damaging the connectors.
The sixth reason is the breakdown of the power button or the cable that goes to it. This is especially true for models where the button is embedded in the top panel of the case or the keyboard. Externally, it can be pressed as usual, but the electrical signal is
