You pressed the power button, but instead of the usual 20-30 seconds, the screen remains black, the loading indicator spins, and the system starts in 5-10 minutes — or even hangs on the manufacturer’s logo? Slow booting of a laptop is annoying, especially when you need to get started quickly. But in 90% of cases the problem can be solved without contacting a service center.

In this article we will look at all possible reasons - from clogged startup to hardware faults, and we’ll also give step by step instructions for diagnostics and acceleration of startup for Windows 10/11 And macOS. You will learn which programs slow down the system, how to check your hard drive for errors, and when it's time to change the battery or thermal paste. Let's start with the simplest ones and gradually move on to complex cases.

1. Startup: Invisible programs that steal your time

The most common reason for long loading times is dozens of programs, which automatically start along with the system. Even if you don't see them, they load in the background, take up RAM and force the processor to work at its limit. This is especially critical for laptops with 4-8 GB RAM And HDD instead of SSD.

How to check? B Windows open Task Manager (combination Ctrl + Shift + Esc), go to the tab Autoload. Here you will see a complete list of programs, their impact on system startup (High, Average, Low) and loading time. If there are more than 10 items on the list, this is already a reason for optimization.

  • 🔍 Antiviruses (Avast, Kaspersky, Norton) - often take the longest to load, even if you don’t use them.
  • 🎮 Game launchers (Steam, Epic Games, Origin) - check for updates every time you turn on.
  • 📱 Messengers (Telegram, Discord, Skype) - launch automatically, although you can open it manually.
  • ☁️ Cloud storage (Google Drive, OneDrive, Dropbox) - synchronize files in the background.

There is no need to disable everything - some programs (for example, drivers for a touchpad or video card) are critical for operation. But if you see Adobe Creative Cloud, NVIDIA GeForce Experience or iTunes Helper — feel free to disable their autoloading. On macOS a similar list can be found in System Preferences → Users and Groups → Login Items.

2. Hard disk (HDD) vs SSD: why the difference is 10 times

If your laptop is older than 5-7 years, there is a high probability that it has mechanical hard drive (HDD). Even the fastest HDD with turnover 7200 rpm works in 10-20 times slowerthan modern SSD. This means that the system will boot not for 20 seconds, but 3-5 minutes - and this is under ideal conditions.

How to check disk type? B Windows open Explorer, right click on the disk C:, select Properties → Equipment. If the model contains words HDD, SATA or 5400 rpm - your laptop runs on outdated technology. On macOS open About This Mac → System Report → Storage.

Parameter HDD (5400 rpm) HDD (7200 rpm) SSD (SATA) SSD (NVMe)
Reading speed 80-100 MB/s 120-150 MB/s 500-550 MB/s 2500-3500 MB/s
Windows boot time 3-5 minutes 2-3 minutes 15-30 seconds 10-20 seconds
Cost (1 TB) 2 000–3 000 ₽ 3 000–4 000 ₽ 6 000–8 000 ₽ 8 000–12 000 ₽

The solution is simple: replace HDD with SSD. Even budget SATA SSD (For example, Crucial MX500 or Samsung 870 EVO) will speed up loading in 5-10 times. If the laptop has a slot for M.2 NVMe (check the model documentation), you can install an even faster drive. For macOS the process is more complicated - in some models (for example, MacBook Pro 2015-2017) the disk is soldered, and it is impossible to replace it without a soldering iron.

💡

Before replacing the drive, copy all important data to an external drive or to the cloud. Transferring the system to a new SSD can be done using the program Macrium Reflect (Windows) or Carbon Copy Cloner (macOS).

3. Viruses, mining and malware: hidden threats

If your laptop starts to boot slowly suddenly (for example, everything was working fine yesterday), the reason may lie in viruses or miners. Malware not only steals data, but also uses the resources of your processor/video card to mine cryptocurrency or send spam. This leads to the system “thinking” for 5-10 minutes when turned on.

How to check? Run full check using built-in Windows Defender (Start → Settings → Update & Security → Windows Security → Virus & Threat Protection) or third-party antivirus (Kaspersky Virus Removal Tool, Dr.Web CureIt!). Pay attention to the processes in Task Manager: if some unknown .exe-file is loading CPU on 80-100%, this is a sure sign of infection.

  • ⚠️ Trojans — disguised as system files (for example, svchost.exe or explorer.exe).
  • 💰 Miners - use a video card (NVIDIA/AMD) for mining Monero or Bitcoin.
  • 📧 Rootkits — are embedded in the core of the system and are difficult to detect using standard means.

If the antivirus does not find anything, but suspicions remain, check the laptop using Live CD (For example, Kaspersky Rescue Disk). This is a boot disk with an antivirus that scans the system before starting Windows/macOS and can detect hidden threats. For macOS use Malwarebytes or Avast Security.

How to create a bootable USB flash drive with antivirus?

1. Download the image Kaspersky Rescue Disk from the official website.

2. Use the program Rufus (Windows) or dd (macOS/Linux) for recording to a flash drive.

3. Boot from the flash drive (in BIOS select USB-HDD as the first boot device).

4. Perform a full scan of all drives.

4. RAM: when it’s not enough

If your laptop 4 GB RAM or less, the system can "to choke" when loading - especially if there are 10-15 programs hanging in autorun. Windows 10/11 requires a minimum 4 GB for normal operation, and macOS Monterey and newer - 8 GB. When there is insufficient memory, the system starts using swap file on the hard drive, which slows down the startup significantly.

How to check? B Windows open Task Manager → Performance → Memory. If in the section Used constantly 80-100% - there is a critical shortage of memory. On macOS open System Monitoring → Memory and look at the graph Memory pressure (if it is red, you need to add RAM).

⚠️ Attention: If you see a message "Not enough memory" when starting the browser or Photoshop, this means that the system is already operating at its limit. Adding RAM only makes sense if the laptop has free slots (check the documentation or using the program CPU-Z).

Solutions:

  • 🔄 Close unnecessary programs in startup (see section 1).
  • 🔧 Increase the swap file (but this is a temporary solution - it is better to add physical memory).
  • 💻 Upgrade your laptop - if the model supports 16 GB RAM or more.

Open Control Panel → System → Advanced system settings → Performance → Settings → Advanced → Virtual memory → Change|Uncheck "Automatically select paging file size"|Select disk C: and enter the size manually (recommended 1.5 × amount of RAM)|Click "Set" and restart the laptop-->

5. Broken file system and disk errors

If laptop Stuck on Windows logo or macOS, and then “thinks” for a long time before loading the desktop, the problem may be damaged system files or bad sectors on disk. This is especially true for HDD, which wear out over time, but also SSD are not immune from failures.

How to diagnose? B Windows open Command line as administrator and do:

chkdsk C: /f /r

This command will check the disk for errors and try to fix them. If the system does not allow you to check immediately, agree to reboot. For macOS use Disk Utility (Programs → Utilities → Disk Utility) and press First aid.

If chkdsk finds errors, but cannot fix them, or the disc produces extraneous sounds (clicking, grinding) - this is a sign physical wear and tear. In this case, it is urgently necessary save data and replace the drive. For SSD the critical signal is the parameter Reallocated Sectors Count in the program CrystalDiskInfo - if its value increases, the disk will soon fail.

💡

If the laptop suddenly starts to take longer to boot than usual, but before that it was emergency power outage (for example, the battery is dead), with a 90% probability a damaged file system is to blame. In this case it will help chkdsk or reinstalling the OS.

6. Overheating and thermal throttling: when the laptop “suffocates”

If the laptop not only takes a long time to boot, but also turns off after 5-10 minutes of operation, the reason may be overheating. Modern processors (Intel Core i7/i9, AMD Ryzen 7/9) automatically reduce performance at high temperatures (90°C+), which leads to thermal throttling — artificial deceleration to protect against damage.

How to check the temperature? Use programs:

  • 🌡️ HWMonitor (Windows) - shows temperature CPU, GPU and disk.
  • 🍎 iStat Menus (macOS) - Displays real-time temperature in the menu bar.
  • 🔥 Core Temp — specializes in CPU monitoring.

Normal loading temperatures:

  • 🟢 30-50°C - optimal.
  • 🟡 50-70°C - acceptable, but it’s worth cleaning the laptop.
  • 🔴 70°C+ - critical, urgent intervention required.

Solutions:

  1. Clean the cooling system — dust in the radiator and fan impairs heat dissipation. Use a can of compressed air or contact service.
  2. Replace thermal paste — over time, it dries out and ceases to effectively remove heat. Pastes suitable for laptops Arctic MX-4 or Noctua NT-H1.
  3. Use a cooling pad - especially relevant for gaming laptops (ASUS ROG, MSI, Acer Predator).
How to clean your laptop from dust yourself?

1. Turn off the laptop and disconnect the battery (if it is removable).

2. Unscrew the back cover (you need a screwdriver Phillips #0 or T5).

3. Carefully blow off dust from the radiator and fan using a can of compressed air.

4. Check the thermal paste - if it is dry or leaking, replace it.

5. Reassemble the laptop and turn it on.

⚠️ Do not use a vacuum cleaner - it can damage components with static electricity!

7. Outdated BIOS/UEFI firmware and drivers

If laptop stuck on the manufacturer's logo (Lenovo, HP, Dell, Acer) or “thinks” for a long time before booting the system, the problem may be outdated BIOS/UEFI firmware. Manufacturers regularly release updates that fix compatibility issues with new versions Windows or macOS.

How to update BIOS/UEFI?

  1. Find out the exact model of the laptop (on the sticker below or in system information).
  2. Download the latest firmware from the manufacturer's official website (for example, support.lenovo.com for Lenovo).
  3. Follow the instructions - usually you need to run .exe-file from under Windows or create a bootable USB flash drive.
⚠️ Attention: Update BIOS/UEFI - a risky operation. If the power goes out during the process or the laptop freezes, the motherboard may fail. Update the firmware only if you are sure of the stability of the power supply and follow the official instructions.

Also check drivers - especially for:

  • 🖥️ Video cards (NVIDIA, AMD, Intel).
  • 🔊 Sound card (Realtek, Dolby).
  • 📶 Wi-Fi/Bluetooth adapter (Intel, Qualcomm, Broadcom).

To automatically update drivers in Windows use:

  • Driver Booster (IObit).
  • Snappy Driver Installer (SDI).
  • Built-in Device Manager (right click on the device → Update driver).

8. Hardware faults: when it’s time for service

If you have tried all the tips above and the laptop still boots longer than 5 minutes, the problem may be hardware failure. Here are the signs when you should contact a service center:

  • 🔋 Battery Bloated — if the laptop case is deformed, the battery must be replaced urgently (risk of fire!).
  • 💥 Laptop turns off for no reason - the motherboard or power supply may be faulty.
  • 🔌 Charging does not work — a problem with the power controller or connector.
  • 💾 Disk is not detected in BIOS - physical damage HDD/SSD.
  • 🔥 Smells like burning — components burned out (video card, south/north bridge).

Some problems you can diagnose yourself:

  • Battery: open Command line and do: 
    powercfg /batteryreport

    Open the generated file battery-report.html and check the parameters Full Charge Capacity (if it is less 50% from Design Capacity, it's time to change the battery).

  • RAM: use MemTest86 to check for errors (runs from a flash drive).
  • Video card: Screen artifacts or blue screen (VIDEO_TDR_FAILURE) talk about a malfunction GPU.

If the laptop is under warranty, do not disassemble it yourself! Contact an authorized service center. For older models (5+ years), repairs may be unprofitable - in this case, it is easier to buy a new laptop or used replacement parts.

💡

If laptop turns on but the screen remains black, try connecting an external monitor. If the image appears, the problem is in the matrix or cable. If not, the video card or motherboard is faulty.

FAQ: Frequently asked questions about laptop loading slowly

❓ The laptop began to boot slowly after updating Windows. What to do?

If the problem appears after major update (for example, with Windows 10 on Windows 11), try:

  1. Roll back to the previous version (within 10 days after the update: Settings → Update & Security → Recovery → Go back to a previous version of Windows).
  2. Reset BIOS settings to factory defaults (Load Default Settings).
  3. Remove conflicting drivers (especially for the video card and Wi-Fi).

If all else fails, reinstall the system from scratch.

❓ macOS takes a long time to load after updating. How to speed it up?

For macOS (especially Monterey, Ventura, Sonoma) brakes are typical after updates. Will help:

  • Reset NVRAM (turn off your Mac, turn on while holding down Option + Command + P + R for 20 seconds).
  • Reset SMC (for MacBook with non-removable battery: turn off, hold down Shift + Control + Option + power button for 10 seconds).
  • Shutdown FileVault (if you don't use encryption: System Preferences → Protection and Security → FileVault).
❓ The laptop takes a long time to load only from the battery, but from the network - quickly. What's the matter?

This is a typical sign worn out battery or faulty power controller. When running on battery power, the processor limits performance to conserve battery power. Check:

  • Battery status powercfg /batteryreport (see section 8).
  • Power settings in Control Panel → Power Options (select scheme High performance).
  • Battery temperature - if it overheats, the laptop may artificially slow down.

If the battery is swollen or its capacity has dropped below 30%, replace it.

❓ Is it possible to speed up booting a laptop with an HDD without replacing it with an SSD?

Yes, but the effect will be minimal. Try:

  • Disable file indexing (Services → Windows Search → Stop).
  • Execute defragmentation (Disk optimization on Windows).
  • Decrease paging file size or move it to another drive.
  • Use ReadyBoost (if you have a USB flash drive with high reading speed).

However, even all these measures cannot be compared with the transition to SSD — the difference in download speed will remain multiple.

❓ The laptop gets stuck on “Preparing Windows” or “Computer Diagnostics”. What to do?

This is a sign damaged system files or driver conflict. Try:

  1. Load into Safe Mode (when turning on, hold down F8 or Shift + F8).
  2. Restore system via Restore point (Start → Settings → Update and Security → Recovery).
  3. Boot from Windows installation flash drive and choose Startup Recovery.
  4. If all else fails, reinstall the system while saving the files.
