Have you pressed the power button and the screen only lights up after 5 minutes? Or does the cursor take forever to appear, but the desktop loads like in the 2000s? Slow laptop startup is a problem that every second user faces, but most simply get used to waiting. Meanwhile, even on older devices, loading can be accelerated by 2-3 times, if you know where to look for the “brakes”.

In this article we will look at all possible reasons - from a banal startup blockage to hidden viruses and hardware malfunctions. You will learn how to diagnose the problem in 10 minutes, what Windows/macOS/Linux settings affect speed, and when it’s time to take your laptop to a service center. And at the end it awaits you 7 step checklist, which will return the device to its former agility.

1. Startup: why 20 programs start with Windows

The most common reason for slow startup is oversaturated startup. Every installed program tends to be added to the automatic startup list, even if you only need it once a month. As a result, the system spends minutes loading Steam, Skype, Adobe Creative Cloud and a dozen other “useful” utilities that you have long forgotten.

How to check? On Windows, click Ctrl + Shift + Esc, go to the tab Autoload. Here you will see a complete list of programs and their impact on launch (high/medium/low). On macOS open System Settings → Users and Groups → Login Items.

  • 🔍 Diagnostics: If there are more than 10 items on the list, this is already critical. Particularly dangerous antiviruses (For example, Kaspersky or Avast), torrent clients and cloud storage.
  • ⚡ Solution: Disable everything except antivirus and drivers (for example, for a printer or graphics tablet). Programs like Discord or Telegram can be started manually.
  • ⚠️ Exception: Do not touch system processes with names svchost.exe, explorer.exe or msconfig — disabling them will lead to failures.
📊 How many programs are in your startup?
  • 0-5
  • 6-10
  • 11-15
  • More than 15
  • I don't know

Critical fact: On laptops with HDD (not SSD), each extra program in startup increases startup time by 15-30 seconds due to slow disk read speed.

2. Viruses and malware: how they steal resources when launched

Viruses rarely advertise their presence - they prefer to work in the background, hijacking system processes during loading. For example, a Trojan Emotet can replace legitimate Windows services, and mining bots (XMRig) load the processor 100% even before the desktop appears. Result: the laptop “thinks” for 5-10 minutes, and the cooler works like a turbine.

How to detect?

  • 🛡️ Launch full check antivirus (for example, Malwarebytes or Dr.Web CureIt!). Ordinary Windows Defender not enough - it misses up to 30% of threats.
  • 🔧 Check it out Task Manager (tab Details). Look for processes with strange names (for example, csrss.exe in several copies) or high CPU consumption.
  • 📊 Use Process Explorer from Microsoft - it will show launch chain processes (who loads what at startup).
Signs of a virus in startup

If when you start your laptop you see:

  • Black screen for more than 2 minutes (no Windows/macOS logo),
  • Flashing cursor on a blank background,
  • Pop-up windows with advertisements before the desktop loads,

- this is a 90% chance of infection bootkit (a virus that embeds itself in the boot sector).

⚠️ Attention: Some viruses block access to Task Manager or antiviruses. If when you press Ctrl+Alt+Del nothing happens - boot into Safe Mode (hold F8 or Shift when turned on) and scan the system from a flash drive (Kaspersky Rescue Disk).

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

If your laptop is older than 2018, it most likely has HDD (hard drive). His reading speed is 80-120 MB/s, whereas even a budget SSD issues 500-3000 MB/s. The difference in system load can reach 10 times the value: 30 seconds on SSD versus 5 minutes on HDD.

How to check disk type?

  1. Windows: open Explorer → This PC, right click on the disk C: → Properties → Equipment.
  2. macOS: About This Mac → System Report → Storage.
Parameter HDD SSD (SATA) SSD (NVMe)
Reading speed 80-120 MB/s 500-550 MB/s 2000-3500 MB/s
Windows boot time 3-5 minutes 20-30 seconds 10-15 seconds
Cost (1 TB) 3 000 ₽ 8 000 ₽ 12 000 ₽
Resource (write cycles) 50 000 300 000 600 000

Solution: If the laptop has an HDD, replacing it with an SSD will give maximum speed increase (even on the old Core i3). Suitable form factor for most models 2.5" SATA (For example, Samsung 870 EVO or Crucial MX500). For modern ultrabooks - M.2 NVMe (WD Black SN770).

💡

Before replacing the drive, clone the system to the new SSD using Macrium Reflect or Clonezilla - this will save all settings and programs.

4. Disk fragmentation: why the HDD “suffocates” over time

If you have a HDD, then over time the files on it fragmented - are broken into small pieces scattered throughout the disk. To read one file, the HDD head has to “jump” across the platter, like a turntable needle. On SSD, fragmentation is not critical (due to the lack of moving parts), but on HDD it increases boot time by 40-60%.

How to check fragmentation?

  • Windows: open Disk optimization (find through search) → select disk C: → Analyze.
  • If fragmentation > 10% - Defragmentation required.

Important: Defragment the SSD it's impossible - this reduces the life of the drive. For SSD use the command optimize-volume in PowerShell:

Optimize-Volume -DriveLetter C -Defrag:$false -SlabConsolidate
⚠️ Attention: If laptop turns off during defragmentation (for example, due to a dead battery), this may lead to data loss. Connect your device to the network and wait for the process to complete.

5. Lack of RAM: when 4 GB is no longer enough

If your laptop 4 GB RAM or less, Windows 10/11 will be actively used swap file (virtual memory on disk). This slows down loading in 2-3 times, because HDD/SSD work much slower than RAM. The situation gets worse if there are “gluttonous” programs like Chrome (each tab eats ~500 MB) or Photoshop (1.5-2 GB).

How to check?

  • Open Task Manager → tab Performance → Memory.
  • If free < 1 GB when idle, there is a critical shortage of memory.

Solutions:

  • 🔧 Add RAM: Most laptops allow you to expand the memory to 8-16 GB. Check compatibility on the manufacturer's website (for example, Crucial System Scanner).
  • 📉 Disable unnecessary services: Enter in search msconfig → tab Services → disable everything except system ones (check Don't show Microsoft services).
  • 💾 Increase the swap file: Control Panel → System → Advanced Settings → Performance → Settings → Advanced → Virtual Memory. Set size 1.5-2 times more RAM (for example, for 4 GB of RAM - 6-8 GB of page file).

6. Outdated BIOS/UEFI firmware: why updating speeds up booting

Firmware BIOS/UEFI - this is the “operating system” of the motherboard, which controls the boot of the laptop even before Windows starts. An outdated version may contain bugs, due to which:

  • Laptop hangs on the manufacturer's logo for a long time (up to 1-2 minutes),
  • Does not recognize SSD or new processor,
  • Loading with errors (CPU Fan Error, No Boot Device).

How to update BIOS?

  1. Find out the motherboard model: enter in the command line wmic baseboard get product,manufacturer.
  2. Download the latest firmware from official website manufacturer (for example, Lenovo Support, HP SoftPaq, ASUS EZ Flash).
  3. Follow the instructions - usually the update occurs through USB flash drive or a special utility in Windows.
⚠️ Attention: Do not turn off the laptop while updating the BIOS - this can do it inoperative (reflashing on the programmer is required). Use an uninterruptible power supply (UPS) or laptop with >50% battery charge.

Make sure that the firmware model matches your motherboard|Download the firmware ONLY from the official website|Disable BitLocker (if used)|Connect the laptop to the network|Do not interrupt the update process

7. Hardware problems: when the hardware is to blame

If all software methods have been tried, but the laptop still starts like Pentium 4, the problem may lie in hardware:

  • 🔋 Dead battery: If the battery is worn out (>500 cycles), the laptop may not getting enough food when turned on, which leads to multiple reboots. Check wear through PowerShell: 
    powercfg /batteryreport

    Look for the line Design Capacity vs Full Charge Capacity. If the difference is >30%, it’s time to change the battery.

  • 🌡️ Overheat: A clogged cooling system causes the processor to throttle (reduce frequency) already at startup. Use HWMonitor to check temperatures. Norm: 40-60°C in idle time, 70-85°C under load.
  • 💽 Faulty drive: If HDD/SSD "crumbles" (bad sectors appear), the system spends minutes trying to read again. Check disk health via CrystalDiskInfo (parameter Reallocated Sectors Count should not grow).

What to do?

  • Clean the laptop from dust (especially the ventilation grilles and radiator).
  • Replace the thermal paste (if the processor temperature is >85°C when idle).
  • Check the contacts of the RAM and SSD - sometimes it is enough to reconnect them.
💡

If laptop turns off 5-10 minutes after startup - this is 99% overheating. Clean the cooling system immediately or contact service.

FAQ: Frequently asked questions about slow laptop startup

❓ The laptop takes a long time to start only after turning it off, and after a reboot it starts quickly. What's the matter?

This is typical Windows 10/11 behavior when hybrid shutdown (fast startup). The system saves the OS kernel to a file hiberfil.sys, but when completely turned off, some drivers (especially video cards) are not restored correctly.

Solution: Disable hybrid startup:

  1. Open Control Panel → Power Options.
  2. Click What the power buttons do → Change settings that are currently unavailable.
  3. Uncheck Enable Fast Startup.
❓ On macOS, the laptop hangs on a “white screen” for 5 minutes. What to do?

On MacBook A "white screen" on startup is usually associated with:

  • Corrupted NVRAM cache (reset: Cmd + Option + P + R when turning on, hold for 20 seconds).
  • Faulty SSD (check via Disk Utility in recovery mode).
  • Conflict of launched programs (boot into Safe Mode, holding Shift).

If the problem persists, reinstall macOS via Recovery Mode (Cmd + R at startup).

❓ Is it possible to speed up Linux boot?

Yes! In Linux, the main “brakes” are:

  • System Manager systemd (check the download with the command systemd-analyze blame).
  • Unnecessary services (disable via sudo systemctl disable servicename).
  • Slow swap (if you are using HDD, disable swap or transfer to SSD).

To speed up:

sudo systemd-analyze critical-chain

sudo journalctl -b | grep -i slow

❓ The laptop takes a long time to start after updating Windows. How to roll back?

Windows updates (especially large ones like 22H2) drivers often break. To rollback:

  1. Go to Settings → Update & Security → Recovery.
  2. Click Start under the item Go back to a previous version of Windows.
  3. If the option is not available, use restore point (rstrui.exe in search).

If rolling back doesn't help, check driver compatibility on the laptop manufacturer's website.

❓ How to check what exactly is slowing down the download?

For detailed diagnostics use:

  • Windows: Boot Trace (type in the command line as admin: perfmon /rel).
  • macOS: sudo fs_usage -w -f filesys boot (in Terminal).
  • Linux: dmesg | grep -i slow.

These commands will show which processes or drivers block download longest.
