Thread summary: reports a PC that stops at a "Press F1" POST message and never reaches the desktop. suggested a backup battery issue and noted replacing the battery does not always cure the problem. The replies point in useful directions; the checklist below adds diagnostics and safe next steps to narrow the root cause.

Key diagnostic checklist:

  • Capture the exact POST text (any preceding lines matter). Many BIOS messages include a clue such as "CMOS checksum error", "Keyboard error", or "No boot device".
  • Attempt to enter BIOS/Setup (Del/F2/F10 depending on the board) and check date/time, boot order, and any logged errors. A repeatedly-reset date/time strongly suggests the board backup battery or a CMOS reset.
  • Test keyboard presence: try a different keyboard and port (PS/2 vs USB). Some systems pause on F1 when a keyboard is not detected.
  • Disconnect nonessential devices (USB drives, external HDDs, extra internal drives, optical drives) and boot with a minimal configuration to isolate a failing drive or peripheral.
  • If BIOS access is impossible and CMOS symptoms persist, try a CMOS clear (jumper on the motherboard) before or in addition to replacing the coin cell; some boards require both.
  • For laptops, consult the service manual before opening; some batteries are soldered or behind complex assemblies.

If the above does not resolve the halt, the issue can be a failing drive, corrupted BIOS, or a motherboard fault. Reflashing BIOS or running a manufacturer hard-drive diagnostic from a USB boot tool can help confirm drive health. Observe ESD precautions and power off/unplug before opening the case.

The CMOS battery needs changed. If it is a desktop it will probably be a non-rechargeable 3v cr2032 button battery. If it is a laptop you will have to open it up and investigate.

I think not like that. you can change it but some time it not work after change.
