Now we will consider how to turn on the laptop without the power button. There are situations in which to bring the device into working condition is urgent. However, the start button at this point may “refuse” to work. Let's try to figure out what to do in a similar situation.
Instruments
So, let's start a direct discussion of the question of whether it is possible to turn on a laptop without a power button and how to do it. First, we need the following tools: a soldering iron, neutral flux, electrical tape, a screwdriver and pliers equipped with an insulated handle, a tester. The situations are different, for example, if you are using an HP laptop, the start button can jam in the plastic panel. This often happens with devices from other manufacturers. In any case, in this state, the laptop is useless. First of all, we clarify whether the warranty period at the service center has expired. The fact is that we have to disassemble the device, which will make it impossible to further free repair.
Input device
Before moving on to radical measures, let's discuss how to turn on a laptop without a power button from the keyboard. A similar possibility exists, but it must be configured in advance, while the device is still working well. To activate the necessary function, go to the BIOS. To do this, continuously press the Delete button. The BIOS menu appears. We use arrows to work with it. If we have an HP laptop in front of us, go to the Power Management Setup section. Open the power settings. To do this, use the item Power on Function. In some BIOS models, the required function may be called Power On by PS2 KB / MS. Next, indicate the method of turning on the laptop. So that he comes to working condition with a single key, select Any Key. Confirm the changes with the F10 key and press Enter. To enable it by a certain button, select Hot Key instead of Any key. Specify the most appropriate key combination. Apply the changes using F10.
If the laptop does not turn on and the previously described settings were not made, it cannot be activated from the keyboard, so go to the next section of this material. It describes the process of phasing out the problem.
Disassembly
In order to figure out how to turn on the laptop without the power button and why it "refuses" to work, we remove the battery. As soon as the battery is removed, go to the next step. The laptop model is of great importance here. It depends on it where the power button is located: on the case, on the side, near the keyboard, on the panel at the top. Let's start with the last option. If the button is located on the panel above, we need a neutral flux, a screwdriver and a soldering iron. Gently pry up the bezel. To do this, use a screwdriver. Next, solder the two conductors, thereby bringing them up. To do this, drill two holes on the top panel. This is required because it is not recommended to use an open device. Set the panel in place. We carry out all actions carefully so that a short circuit does not occur.
To the last screw
Now we will consider how to turn on the laptop without the power button, if the element of interest to us is located on the side of the case. In this case, we disassemble the entire apparatus. We start with the display. Remove the lids from the mounts on it. Next, go to the keyboard. Disconnect it. Unscrew all screws from the bottom cover, remove the top one. We get access to the very place to which the button is connected. Solder two parallel conductors under a neutral flux. We bring them out. We assemble the laptop in the opposite order. The last to connect the battery, as well as the network cable.
Launch
The laptop model does not have much significance when using this instruction, since the basic elements of various laptop computers are similar. Turn on the laptop. To do this, using tools with insulated handles, we connect wiring to each other. Use pliers or a screwdriver. Thus, it will be possible to avoid an unpleasant and painful electric shock. There are cases in which the button is pressed and is in its place, and the laptop for some reason does not want to turn on. It is especially necessary to understand the reasons. This situation can be caused by minor malfunctions and major breakdowns. In the first case, the problem can be fixed with your own hands. Sometimes starting does not occur, as the battery or connection cord has been damaged.
External elements
Check the outlet for voltage. If it is present, disconnect the cord from the laptop and check it on the connection. If the problem is caused by the battery, remove it and connect the device directly to the power source. We perform similar actions with a special device - a tester. When replacing the battery, disconnect the laptop from the power source.
Solving problems with starting the device is much more difficult if the damage affected the basic input / output system, video card or microcircuit. In this case, it is possible to determine the cause of the breakdown only with special instruments - an oscilloscope or probes. You will have to do this in the service center. Another problem that only experts can solve is the unexpected hovering and refusal of the reset button to work. Now you know how to turn on the laptop without the power button.
