ASUS Vivobook laptop does not turn on when you press the button - what to do?

Yours ASUS Vivobook stopped turning on after pressing the power button, and the screen remains black? This problem occurs in models Vivobook S14/S15, X415, X515, Pro 14/15 and other series, but the reasons can be radically different - from a banal dead battery to serious malfunctions of the motherboard. In 60% of cases, the laptop can be “reanimated” on its own, without resorting to expensive repairs.

In this article we will look at all possible reasons, according to which ASUS Vivobook does not turn on - from obvious to hidden. You'll learn how to test the power supply, reset the BIOS, diagnose hardware failures, and even restore your laptop after a failed update. And if the problem turns out to be more serious than it seemed, we will tell you how to save on repairs and not run into scammers in service centers.

1. Primary diagnosis: checking the obvious

Before disassembling your laptop or taking it to a service center, rule out the simplest causes that are often overlooked. Start with visual inspection and checking connections.

The first thing to do is make sure that ASUS Vivobook It really doesn’t turn on, and is not just “silent” due to problems with the screen. Listen: can you hear the sound of the fan, is the power indicator (usually a white or orange LED next to the power button) blinking? If yes, the problem may be matrix, cable or backlight, and not in the power supply.

• 🔌 Check the power supply: Connect the charger to another outlet (preferably directly, without extension cords). Make sure the cable is not kinked or damaged. On original blocks ASUS The green/blue indicator should be on when connected to the network.
• 🔋 Disconnect the battery (if possible without disassembly): some models Vivobook (For example, X512 or S433) allow you to remove the battery by pulling a special latch on the bottom cover. Try turning on the laptop without a battery, only from the mains.
• 🖥️ Connect an external monitor: If the laptop is alive but the screen is not working, the image will appear on the external display (use HDMI or USB-C). This will help distinguish a video card failure from problems with the matrix.

⚠️ Attention: if laptop ASUS Vivobook does not respond to the power button, but at the same time hot (especially in the processor area), unplug it immediately! This is a sign short circuit on the motherboard, and further power supply may permanently damage the device.

2. Reset BIOS/UEFI: when the laptop freezes at startup

One of the most common reasons why ASUS Vivobook does not turn on - BIOS settings failure. This may happen after:

• ⚡ Unsuccessful BIOS update (for example, via EZ Flash Utility).
• 🔄 Sudden power outage during operation.
• 🛠️ Incorrect overclocking or power management settings.

To reset the BIOS to ASUS Vivobook, try the following methods (from simple to complex):

1. Hard reset: Unplug the laptop, remove the battery (if possible), then hold down the power button 40–60 seconds. This will discharge the capacitors and reset the temporary settings.
2. Reset via CMOS: On some models (eg Vivobook Pro N580) there is a special button CMOS Reset on the bottom cover. Press it with a thin object (a paperclip) for 10 seconds.
3. Removing the CMOS Battery: If you're ready to disassemble your laptop, look for the coin cell battery on the motherboard CR2032, remove it for 5 minutes, then install it back.

Reset method	Suitable for models	Difficulty	Efficiency
Press and hold the power button	All models Vivobook	⭐	30–40%
Button CMOS Reset	Vivobook Pro, some Vivobook S	⭐⭐	60–70%
Removing the CMOS Battery	All models (requires disassembly)	⭐⭐⭐	80–90%

If after resetting the BIOS the laptop turns on but requires setting the date/time, this is normal. Go to BIOS (click F2 or Del at start) and load default settings (Load Default Settings).

3. Power problems: power supply, battery, connectors

If ASUS Vivobook shows no signs of life, maybe he’s to blame power supply, battery or power connector on the motherboard. Diagnosing this is easier than it seems.

How to check the power supply:

• 🔍 Inspect the cable for fractures (especially at the base of the plug). Often the break occurs inside the braid.
• 📊 Measure the voltage at the output of the unit with a multimeter: for most Vivobook it must be 19V–20V (indicated on the block sticker). If the voltage is lower 16V or missing - the unit is faulty.
• 🔄 Try another power supply with the same power (for example, from another ASUS or Lenovo with similar characteristics).

Battery problems: Even if the laptop is connected to the network, a discharged or swollen battery may block it from turning on. Signs of a bad battery:

• The laptop turns on only without the battery.
• The battery is swollen (can be seen from the deformation of the bottom cover).
• ASUS Battery Health Charging previously showed errors on Windows.

⚠️ Attention: if battery ASUS Vivobook swollen, don't turn on the laptop before replacing it! The risk of short circuit and fire is extremely high. Service centers charge from 1,500 to 4,000 rubles for battery replacement (depending on the model).

Power connector on motherboard - the weak point of many Vivobook. If you frequently connect/disconnect charging, the contacts become loose or become unsoldered. Signs:

• The laptop turns on only in a certain position of the plug.
• The charging indicator blinks or does not light up at all.
• When the cable moves, the power is lost.

4. Hardware failures: what could have burned out?

If ASUS Vivobook does not turn on even after checking the power supply and resetting the BIOS, the problem may lie in hardware failure. Let's look at the most vulnerable components:

1. North/south bridge (chipset)

These chips are responsible for communication between the processor, RAM and other components. Signs of their failure:

• The laptop won't turn on, but the cooler starts briefly and immediately stops.
• The power indicators blink in an uncharacteristic manner (for example, 3 times in a row).
• Before the breakdown we observed spontaneous reboots or blue screen (WHEA_UNCORRECTABLE_ERROR).

2. Video chip (integrated or discrete graphics)

On models with discrete graphics (NVIDIA MX250/MX350 or AMD Radeon) happens often chip dump due to overheating. Symptoms:

• The laptop turns on, but the screen remains black (no signal to the monitor).
• When an external display is connected, the image appears.
• Before the breakdown, there were artifacts on the screen (strips, flickering).

3. Capacitors and power circuits

Swollen capacitors or burnt MOSFETs are a common problem after power surges. They can be found when opening the laptop:

• 🔍 Swollen capacitors have convex upper part (must be flat).
• 🔥 Burnt transistors are usually blackened or have a burnt leg.

Critical Information: If your ASUS Vivobook models X512DA, X570ZD or S15 S530 stopped turning on after updating the BIOS in 2022–2023, with an 80% probability a chipset firmware failure is to blame AMD Ryzen 4000/5000. In this case, only flashing it through the programmer in the service will help.

What do burnt elements on the board look like?

The photos below show typical signs of battery failure on the motherboard ASUS Vivobook:

- Swollen capacitor (left) - the upper part is convex, sometimes with electrolyte leaks.

- Burnt MOSFET transistor (right) - blackening of the body or legs.

- Burnt tracks are dark spots on the PCB board.

In most cases, such breakdowns are eliminated by replacing elements (repair cost: 2,000–6,000 rubles).

5. Software failures: when the laptop is “alive”, but does not start

If ASUS Vivobook shows signs of life (indicators are on, the fan is spinning), but does not boot, the problem may be software. Let's look at the main scenarios:

1. Windows bootloader is damaged

Signs:

• The screen is black, but the cursor is blinking in the upper left corner.
• A message appears Boot Device Not Found or No Bootable Device.
• Laptop reboots cyclically on logo ASUS.

Solution:

1. Create a bootable USB flash drive with Windows (on another PC).
2. Connect it to Vivobook and boot into recovery mode (Win + X → Shutdown → Boot into Safe Mode).
3. Run the commands on the command line:

   bootrec /fixmbr
   bootrec /fixboot
   bootrec /scanos
   bootrec /rebuildbcd

2. Crash after updating Windows or drivers

If the laptop stops turning on after the update, try:

• 🔄 Roll back update: boot into Safe Mode (F8 at startup) and uninstall the latest updates in Control Panel → Programs → View installed updates.
• 🛠️ Restore system: Use a restore point (if you have one).
• 🗑️ Reset Windows: From the recovery menu, select Restore your computer to its original state (save the files if possible).

3. Viral infection

Some viruses (for example, ransomware) block the system from loading. Signs:

• A black screen appears with a ransom demand.
• The laptop turns on, but immediately turns off with an error CRITICAL_PROCESS_DIED.

Solution: Boot from LiveCD (For example, Kaspersky Rescue Disk) and scan the disk for viruses.

6. When you can’t do without service: cost of repairs

If all the above methods did not help, and ASUS Vivobook still does not turn on, you will have to contact a service center. Let's look at typical breakdowns and their repair costs (prices are relevant for Moscow and the regions as of 2026):

Breakdown	Repair cost (₽)	Deadlines (days)	Warranty
Replacing the power connector	1 200–2 500	1–2	3–6 months
Repair of power circuits (capacitors, transistors)	2 000–5 000	2–3	6 months
Flashing the BIOS with a programmer	1 500–3 000	1–2	3 months
Replacing the north/south bridge	4 000–8 000	3–5	6 months
Resoldering the video chip (for models with discrete graphics)	5 000–12 000	3–7	6–12 months

Before taking your laptop to a service center, consider a few nuances:

• 🔧 Official service ASUS charges 20–30% more, but gives a guarantee of up to 1 year. Unofficial workshops are cheaper, but the risk of “jambs” is higher.
• 📋 Ask for diagnostics: in normal services it is free or costs 300–500 rubles (this amount will be counted towards the cost of repairs).
• 💰 Compare with the price of a new laptop: if the repair costs more than 50% of the cost VivobookIt may be more profitable to buy a new model.

⚠️ Attention: if you are offered a replacement the entire motherboard Instead of repairing individual elements (for example, the chipset or power circuits), this is a reason to be wary. Often such “repairs” cost 70–80% of the cost of the laptop, while local repairs are 2–3 times cheaper.

FAQ: Frequently asked questions about malfunctions ASUS Vivobook

The laptop does not turn on, but the power light is on. What to do?

If the indicator is on but the screen is black, the problem may be:

• Matrix or cable (try connecting an external monitor).
• RAM (remove the strips and check for oxidation of the contacts).
• Video chip (if the laptop has discrete graphics).

Also try resetting the BIOS (see section 2).

After updating the BIOS, the laptop stopped turning on. How to restore?

If the BIOS update was unsuccessful, this will help disaster recovery:

1. Download the latest BIOS for your model from the website ASUS and rename the file to VIVOBOOK.ROM.
2. Copy it to empty flash drive (FAT32).
3. Connect the flash drive to the switched off laptop, hold down Win + V and hold for 10 seconds, then release and press the Power button.

If this method does not work, you will need programmer (contact service).

The laptop turns on but immediately turns off. What is the reason?

A short-term switching on followed by switching off is usually associated with:

• Overheating (check the cooler and thermal paste).
• Short circuit (inspect the motherboard for burnt elements).
• Faulty RAM (try rearranging the slats or leaving one).

Also the reason may be BIOS failure (see section 2).

How much does it cost to replace a motherboard? ASUS Vivobook?

The cost depends on the model:

• Vivobook X415/X515: 8 000–12 000 ₽.
