Brief expert note: the black screen that simply says "Enter password" is most often a pre‑boot (firmware/BIOS or HDD) lock rather than a Windows account prompt. Given has already removed and replaced the coin cell and still sees the message, that makes a firmware‑level or drive‑level password more likely (many modern Samsung boards store supervisor/HDD passwords in non‑volatile memory). That explains why the simple CMOS‑battery trick mentioned by and sometimes fails. is correct that OEM service can clear these locks but will normally require proof of ownership, and ’s suggestion to use a professional is often the safest route when warranty or data matters exist.

A practical triage sequence (in order):

  1. Check whether the prompt appears before any manufacturer logo — pre‑logo text points to firmware.
  2. Observe Caps/Num Lock LEDs at that prompt to confirm the keyboard is active at pre‑boot.
  3. Try to access a boot menu (F12/F10) or boot from an external USB/live OS; if external boot is blocked, firmware is locking the machine.
  4. Power with the internal drive removed — if the same prompt still appears, the lock is in firmware rather than on the drive.

Remediation and cautions: if file recovery is urgent, the drive can be removed and attached to another computer with a SATA→USB adapter (data is accessible unless the disk is encrypted — BitLocker needs a recovery key). For clearing a firmware password, the legitimate route is an authorized Samsung service center with proof of purchase. Avoid shady “master code” generators or random firmware hacks — they are often scams, risk bricking the laptop, and can void warranties.

Do you mean something like this:

If so it needs your BIOS password, which you should already know if you have configured the PC to require it upon booting. Or is this a secondhand one you've bought and cannot get past this screen?

If the latter then you can reset the thing by opening the computer up and removing the CMOS battery (tons of help online - search Google for it, there will even be YouTube videos if you need them) for ten minutes before putting it back and starting again.

If it is a laptop, you may have to remove the battery and short out a couple of contacts on the motherboard. Check with the Samsung web site's support pages for this system.

Some models have us call in to reset that password if methods you find on the web don't work.

Be ready to prove it's yours since when the maker does this it's a form of theft protection. The makers sometimes get flamed over this but hey, if it's yours legitimately, it's like you locked your keys in your car and pay a little to the locksmith.

It must be worth it to get this done, right?
