I recently bought a Nimo N153 gaming laptop with 16 GB of RAM and am using Windows 11 for the first time. After watching YouTube, the laptop suddenly showed an error screen saying it needed to restart, apparently during or after a Windows update. It remained stuck for about an hour, so I held the power button to shut it down. Since then, booting has been extremely inconsistent: sometimes I get a black screen, sometimes the Nimo logo, and sometimes a Nimo repair screen with no usable options. I have also occasionally seen Windows' automatic repair process, but it never completes. I cannot reliably access the BIOS or recovery environment, and the only keyboard shortcut that sometimes responds is Fn+F9. Support suggested interrupting startup three times to force Windows into recovery mode, then uninstalling the latest update or resetting Windows while keeping my files, but the laptop often fails before I can do any of that. I have owned it for only a month and am willing to wipe it, but I would prefer to determine whether this is a Windows problem, overheating, firmware trouble, or defective hardware before taking it apart.

If you can get a stable display, try entering firmware setup immediately after powering on using the manufacturer's documented key—often F2, Delete, or Esc, sometimes with Fn. An external monitor can also help determine whether the laptop screen is the issue. If BIOS works reliably but Windows does not, create a Windows 11 installation USB on another computer and use its repair options, or reinstall Windows after backing up anything important. Do not repeatedly interrupt startup while a firmware update is in progress, since that can make the laptop unbootable.
The laptop may have overheated if it was resting on a blanket or directly on your lap, especially in a warm environment, but overheating alone does not explain why BIOS access is also unreliable. Use it on a hard surface and let it cool completely, then check whether the fans start and whether the charging light behaves normally. If you still see random black screens, repair screens, or error codes, that is strong evidence for a defective motherboard, memory module, display connection, or power system. Since it is new, opening the chassis could complicate the warranty, so I would ask the seller for an exchange rather than taking it apart.
Because the machine is only a month old and you cannot consistently reach the logo or BIOS, I would treat this as a possible hardware, firmware, or power problem rather than assuming Windows is solely responsible. A Windows update can break boot files, but it normally would not prevent the BIOS screen from appearing. Try a complete power drain: shut it down, unplug the charger, disconnect all USB devices, hold the power button for 30–60 seconds, then connect the charger and try again. If the behavior remains inconsistent, stop troubleshooting internally and use the warranty or return period. Record a short video showing the black screen and failed boots so support can authorize a replacement or repair.
The main problem is that the logo and keyboard response are inconsistent, so I cannot reliably tell whether it is accepting the BIOS key. I will try the power-drain and external-display checks before attempting a reinstall.
