Lenovo laptop stuck on the Lenovo logo or in a boot loop: what to check

You press the power button, the Lenovo logo appears, and then nothing: the laptop sits on the logo, restarts and shows it again, or drops to a black screen. It is one of the most common faults we see on ThinkPads, IdeaPads, Yogas and Legions, and the cause can be anything from a USB stick left in a port to a failing SSD. Here is how to narrow it down safely before you book a repair.

First: rule out the simple causes

• Unplug everything. Remove USB sticks, external drives, docks, SD cards and printers. A laptop can try to start from an external drive and hang on the logo when it finds nothing useful there.
• Do a full power reset. Unplug the charger and hold the power button for 15 to 20 seconds. Many ThinkPads also have a small emergency-reset pinhole on the underside; pressing it with a straightened paper clip, with the charger unplugged, cuts power to the board. Then reconnect the charger and try again.
• Try the charger on its own. A failing charger or a battery at zero can let the laptop show the logo and then shut down. Leave it charging for half an hour before trying again.

Get into Lenovo’s startup menu

If the logo appears, the laptop is at least partly working, and the startup menu tells you a lot.

• IdeaPad, Yoga and Legion: with the laptop switched off, press the Novo button. This is a small button or pinhole, usually on the side of the laptop or next to the power button, often marked with a curved arrow. It opens the Novo menu with options for normal startup, BIOS setup, boot menu and system recovery. On many models you can also tap F2 for the BIOS or F12 for the boot menu as the logo appears.
• ThinkPad: press Enter as soon as the logo appears to open the startup interrupt menu. From there, F1 opens the BIOS and F12 the boot menu, and recent models also offer built-in diagnostics.

If you can reach the BIOS, check two things. Does it list your internal SSD? And is it set as the first boot device? If the SSD isn’t listed at all, the problem is almost certainly the drive or its connection, not Windows.

One warning: don’t clear the security chip or change security settings in the BIOS unless you are certain. On a laptop with BitLocker encryption, that can leave you needing the recovery key to get back into Windows.

Let Windows try to repair itself

When Windows fails to start a couple of times in a row, it should open the recovery screen automatically. From there, Startup Repair fixes many boot problems caused by an interrupted update or a damaged boot file. System Restore takes the laptop back to a point before the problem started, without touching your documents.

If you see a blue BitLocker recovery screen asking for a 48-digit key, don’t keep restarting. The key is usually saved in the Microsoft account used to set up the laptop, or with your workplace IT team if it is a company machine.

Messages that point to a hardware fault

• “Default Boot Device Missing or Boot Failed” or “No bootable device”: the laptop can’t find a working drive. If the SSD is missing from the BIOS, it has failed or come loose.
• The logo freezes even when you try to open the BIOS: this points to a motherboard, memory or firmware problem rather than Windows.
• A boot loop that started after a spill, a drop or a BIOS update: stop trying and get it checked, because repeated restarts won’t fix it and can make some faults worse.

Don’t risk your files

If the SSD is failing, every restart and every repair attempt puts more strain on it. If you have documents, photos or work on the laptop that aren’t backed up anywhere, avoid resetting Windows or reinstalling it: a reset can erase the very files you want. Recovering the data first, then repairing the laptop, is the safer order. Our Lenovo data recovery service handles SSDs that are no longer detected, and laptops that won’t start at all.

What a repair usually involves

On the bench we check whether the drive is readable, test memory and power, and read any error codes from the board. Common outcomes are:

• a software repair or a clean Windows install, with your files copied off first (software repairs);
• a replacement SSD, which on most Lenovo laptops can also be an upgrade (SSD upgrades);
• a motherboard repair where the fault is a failed component on the board.

Book a Lenovo repair

Bring your laptop to our London SE1 workshop (Monday to Saturday, 9am to 6pm), or we can arrange a courier collection from anywhere in the UK. Tell us the model and what the screen shows, and we agree the price with you before any work starts.
