Why does a laptop take a long time to turn on and how to fix it: a complete guide

You pressed the power button, but instead of the usual 10-20 seconds, you wait several minutes - or worse, the laptop stuck on the manufacturer's logo or the Windows spinning circle? The problem of long loading times occurs in 67% of users over 3 years of use, but the reasons may lie not only in the “aging” of the equipment. From overloaded autorun to hidden hardware faults of the hard drivethat are ignored by diagnostic utilities - we will analyze all the scenarios and give clear instructions.

This article does not contain the blanket "reinstall Windows" advice. We will analyze symptoms by loading stage (BIOS → OS logo → desktop), we will identify the culprit of the brakes and offer solutions - from basic (cleaning startup) to advanced (replacing thermal paste or flashing the BIOS). We will pay special attention to laptops Lenovo, HP, Asus And Dell, where the problem is often associated with proprietary utilities, and also consider the specifics MacBook on M1/M2 chips.

1. Diagnostics: at what stage does the laptop slow down?

The first step is to determine where exactly does the delay occur?. This will narrow the range of possible causes from 20 to 2-3. Take a stopwatch (or smartphone) and record the time at each stage:

• 🔋 0–5 sec: The laptop responds to the power button (indicators light up, fan sound is heard) → the problem is power supply or battery.
• 🖥️ 5–30 sec: Black screen or manufacturer's logo (Asus, Acer etc.) → to blame BIOS/UEFI or hardware (RAM, SSD/HDD).
• 🪟 30 sec–5 min: Spinning circle or Windows/Linux logo → problems with the OS bootloader, drivers or disk.
• 📁 5+ min: The desktop appears, but the system “thinks” → startup, background processes or viruses.

If laptop freezes at one stage (for example, on the logo Lenovo), try hold the power button for 15 seconds to force shutdown, then turn on again. Sometimes this helps to “wake up” the system. But if the freeze recurs, read on.

2. Hardware reasons: when the hardware is to blame

If your laptop starts to slow down suddenly (yesterday it worked fine, today it took 10 minutes to load), with a 70% probability the problem is in the hardware. Let's look at typical scenarios:

2.1. Faulty hard drive (HDD) or SSD

Symptoms: laptop Stuck at BIOS logo or in the "Prepare Automatic Repair" step (Windows). HDD often fail due to mechanical damage, SSD — due to exhaustion of the recording resource (especially in laptops 2015–2018).

How to check:

1. Connect the drive to another PC via USB adapter or install it in another laptop.
2. Run the test in CrystalDiskInfo (free utility). If the status is “Pre-failure” or “Alarm”, the disk needs to be replaced.
3. For SSD check the parameter Total Host Writes (total amount of recorded data). If it exceeds 300–500 TB for a 256–512 GB disk - get ready for replacement.

2.2. Problems with random access memory (RAM)

Symptoms: laptop reboots in a loop or gives a blue screen (MEMORY_MANAGEMENT, IRQL_NOT_LESS_OR_EQUAL). Often occurs after cleaning the laptop (the RAM module is poorly inserted) or when overheating (for example, in MacBook Pro 2017–2019).

How to check:

• 🛠️ Turn off the laptop, remove the battery (if removable), then test each RAM module one by one (if there are several).
• 🖥️ Launch MemTest86 (free memory testing tool). Errors in the test? The module is faulty.
• 🔥 Check RAM temperature using AIDA64 (tab Sensors). If higher 80°C — thermal pads need to be cleaned or replaced.

What to do if the laptop does not turn on at all?

If your laptop does not respond to the power button, try:

1. Disconnect the power supply and remove the battery (if possible), hold the power button for 30 seconds (“reset flash memory”).

2. Connect another power supply (even if the indicator is on, the voltage may be insufficient).

3. Check the RAM contacts - sometimes oxidation leads to complete failure.

2.3. Overheating and thermal paste

Laptops HP Pavilion, Asus TUF And Lenovo Legion known for cooling problems. If you hear when you turn on roaring fan, and the case is hot - the reason is overheating. This may block booting until the processor cools down.

Solution:

• 🧊 Remove the bottom cover, clean the radiator from dust (use soft brush and vacuum cleaner).
• 🧴 Replace the thermal paste on the processor and chipset (we recommend Arctic MX-6 or Noctua NT-H2).
• ⚙️ Disable in BIOS Turbo Boost (if any) - this will reduce the temperature by 10–15°C.

3. Software reasons: viruses, drivers and startup

If hardware tests do not reveal any problems, the culprit for the brakes is most likely the software. Let's look at the top 5 software reasons:

3.1. Overloaded startup

Symptoms: laptop takes a long time to load after entering the password (the desktop appears, but the system “thinks” for 2–5 minutes). The culprits are startup programs, especially:

• 🔍 Antiviruses (Kaspersky, Norton, Avast - can add up to 1-2 minutes to the download).
• 🎮 Background processes of game clients (Steam, Epic Games, Origin).
• 📊 Manufacturer's utilities (Lenovo Vantage, HP Support Assistant, MyAsus).
• ☁️ Cloud services (OneDrive, Google Drive, Dropbox).

How to clean startup:

1. Click Ctrl + Shift + Esc, go to the tab Autoload.
2. Sort by Column Impact on launch and disable everything marked "High".
3. For deep cleaning use Autoruns (a utility from Microsoft). Check the sections carefully Logon, Scheduled Tasks And Services.

3.2. Damaged system files or drivers

Symptoms: laptop hangs at "Prepare Windows" stage or gives an error INACCESSIBLE_BOOT_DEVICE. Often occurs after updates or incorrect shutdown.

Solutions:

• 🔧 Launch command line as administrator and do:

  sfc /scannow
  dism /online /cleanup-image /restorehealth

  These commands will repair damaged system files.

• 🔄 Update drivers manually:
  1. Download drivers from the laptop manufacturer's website (do not use DriverPack Solution!).
  2. Remove old drivers via Device Manager (right click → Remove device).
  3. Install new drivers and reboot.

💿 If Windows does not boot at all, create bootable USB flash drive with Media Creation Tool and select System Restore.

3.3. Viruses and mining bots

Symptoms: laptop suddenly started to slow down, even at the BIOS boot stage, artifacts appear or the system reboots. Viruses can modify the bootloader (MBR), which leads to a long disk initialization.

How to check and treat:

1. Boot from LiveCD (For example, Kaspersky Rescue Disk) and scan the system.
2. Check the processes in Task Manager for suspicious names (for example, svchost.exe with high CPU load).
3. Use Malwarebytes to search for rootkits and miners.

4. Problems with BIOS/UEFI: updating and resetting settings

If laptop stuck on the manufacturer's logo or gives errors like Default Boot Device Missing, the problem may be in the settings or BIOS version. Especially relevant for laptops Dell Inspiron, HP EliteBook And Lenovo ThinkPad, where the BIOS often blocks booting due to security settings.

4.1. Reset BIOS to factory settings

How to reset:

1. Turn off the laptop, turn off the power.
2. Remove the battery (if removable) and hold the power button 30 seconds.
3. If there is a jumper CLR_CMOS on the motherboard - short circuit it for 10 seconds.
4. Turn on your laptop and go to BIOS (usually F2, Del or Esc).
5. Select Load Default Settings → Save & Exit.

4.2. BIOS update

An outdated BIOS version may conflict with new ones SSD NVMe or processors (for example, in laptops Asus ROG with Ryzen 5000/6000). Update your BIOS only if:

• 🔄 There is a version on the manufacturer’s website that is newer than yours (check in the BIOS on the Information).
• 🛑 The update description indicates a fix for loading problems.
• ⚡ The laptop is connected to the network (not on battery!).

How to update:

1. Download the firmware from the official website (for example, for Lenovo - section Support → Drivers & Software).
2. Unzip the archive and copy the file to empty flash drive (FAT32).
3. Boot into BIOS, find the partition EZ Flash (or similar) and select the firmware file.
4. Do not turn off the laptop until the process is complete (usually 2-5 minutes).

5. Optimizing Windows for Fast Boot

Even if the laptop is working properly, Windows slows down over time due to fragmentation, temporary files and unnecessary services. Here 5 working methods speed up loading:

5.1. Disabling unnecessary services

Some Windows services start automatically but are rarely used. Disable them:

1. Click Win + R, enter msconfig → tab Services.
2. Check the box Don't show Microsoft services.
3. Disable:
   • 🖨️ Print Spooler (if you are not using a printer).
   • 🎵 Windows Audio (if sound is not needed when loading).
   • 🌐 Offline Files (if you are not using offline network files).

5.2. Setting up the swap file

If you have less than 8 GB RAM, the swap file helps avoid slowdowns. Optimal settings:

1. Right click on This computer → Properties → Advanced System Settings → Performance → Options → Additionally → Virtual memory.
2. Uncheck Automatically select the size of the paging file.
3. Select the drive (better SSD) and install:
   • 📏 Original size: 1.5 × RAM capacity (for example, for 8 GB RAM - 12288 MB).
   • 📏 Maximum size: 3 × RAM capacity (24576 MB).

5.3. Defragmentation (only for HDD!)

If you have HDD, file fragmentation can increase download times by 20–40%. For SSD defragmentation harmful - it reduces disk resource.

How to do:

1. Open This computer, right click on the disk C: → Properties → Service → Optimize.
2. Select drive C: and press Optimize.
3. For deep cleaning use the command:

   defrag C: /L /U /V

   (for advanced users only!).

6. Specifics of Apple laptops (MacBook)

Laptops MacBook Air/Pro on chips M1/M2 They rarely slow down when turned on, but if this happens, the reasons are usually different:

• 🍎 macOS update: If the laptop freezes on Apple logo with progress bar, wait for it to complete (may take up to 30 minutes). Don't turn it off!
• 🔋 Problems with T2 chip: For 2018–2020 models. A security chip failure may block booting. Solution - SMC reset:
  1. Turn off your MacBook.
  2. Clamp Control + Option (Alt) + Shift for 7 seconds, then hold the Power button for another 7 seconds.

🛡️ FileVault: If disk encryption is enabled, booting may take up to 1-2 minutes (normal).

For diagnostics, boot into Safe Mode (hold Shift when turned on). If the laptop boots quickly in safe mode, the software is to blame (uninstall the last installed programs).

How to reset NVRAM on MacBook?

1. Turn off your MacBook.

2. Turn on and immediately press Option (Alt) + Command + P + R.

3. Hold for 20 seconds (on a MacBook with a T2 chip - until the second beep).

4. Release the keys and wait for normal loading.

7. When should I contact the service?

Not all problems can be solved on your own. Contact the service center if:

Symptom	Possible reason	Repair cost (average)
The laptop turns on, but the screen remains black (the backlight works)	Malfunction of the matrix or video card cable	3 000–8 000 ₽
Stuck at BIOS logo after replacing SSD/HDD	Disk and controller incompatibility	1,500–4,000 ₽ (BIOS firmware)
The laptop turns off 5-10 seconds after turning it on	Short circuit on the motherboard	5 000–15 000 ₽
Constant BSOD (CRITICAL_PROCESS_DIED)	Damage to system files or RAM	2,000–6,000 ₽ (diagnostics + RAM replacement)

Service will also be required if:

• 🔧 You are not confident in your skills (for example, you have never disassembled a laptop).
• 💻 The laptop is under warranty (self-repair will void it).
• 🔥 Diagnostics showed motherboard problems (for example, swollen capacitors).
💡

If the laptop is under warranty, do not open it yourself - even for cleaning dust. This will disqualify you from receiving free repairs.

FAQ: Frequently asked questions

❓ The laptop takes a long time to load only when you turn it on for the first time. What's the matter?

This is normal behavior for Windows 10/11 - the system performs background tasks (updates, defragmentation, disk check). If the download takes more than 2 minutes, check startup and disk status (CrystalDiskInfo).

❓ Could slow loading be due to viruses?

Yes, some viruses (for example, rootkit) modify the Windows boot loader, which increases initialization time. Download Kaspersky Virus Removal Tool and scan the system from a bootable USB flash drive.

❓Laptop Lenovo hangs on "Preparing Automatic Repair". What to do?

This means that Windows cannot boot due to corrupted system files. Try:

1. Boot from installation flash drive Windows.
2. Select System Restore → Command line.
3. Run the commands:

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

If it doesn't help, reinstall Windows.

❓ How to speed up loading MacBook on the M1 chip?

On Apple Silicon (M1/M2) loading usually takes 5-10 seconds. If longer:

• Disable unnecessary programs in System Preferences → Users and Groups → Login Items.
• Reset NVRAM (instructions above).
• Update macOS to the latest version (in System settings → Software update).

❓Laptop HP writes "Boot Device Not Found". What is this?

The error means that the BIOS does not find the boot disk. Reasons:

• 🔌 The cable is disconnected HDD/SSD (often on laptops HP Pavilion).
• 💽 The disk is faulty or formatted.
• ⚙️ Disabled in BIOS Legacy Support (needed for old HDD).

Solution: go to BIOS (F10), check the boot order (Boot Order) and disk status.
