My ASUS laptop suddenly shut down while I was watching a video in Brave, even though it was connected to the charger. I had just received a low-battery warning, and after the shutdown it booted straight into the BIOS instead of Windows.
The BIOS shows the Intel Core i7-12650H processor, 16 GB of RAM, a 98% battery level, and BIOS version 317, but the storage section says "No Storage Device Present" and the boot priority list is empty.
A service center removed and reseated the SSD, cleaned the connector, and tested the drive in another device. It still was not detected there, so the SSD itself appears to have failed.
What could make an NVMe SSD suddenly disappear completely? Could the charging or power problem have caused the failure, or might the SSD have already been failing? Is this more likely to be a controller or firmware problem than a NAND failure, and is there anything safe to try before replacing it? Recovering the important files is my priority, so I want to avoid formatting or making the situation worse.

This sounds most consistent with a controller or firmware failure. Heat can be especially hard on NVMe controllers in laptops, particularly when the drive has little or no heatsinking. A sudden power loss can also leave the SSD's internal metadata in a bad state, although it is impossible to tell whether the power issue caused the SSD failure or was caused by it.
If the data is valuable, avoid DIY recovery attempts and get an evaluation from a reputable recovery service. They may be able to repair the board or get the controller working long enough to image the NAND, but normal recovery software will not help while the operating system cannot see the drive at all.
If the files are not important enough to justify professional recovery, replacing the SSD is probably the practical fix. If they are important, leave the original drive powered off and get a quote from a proper recovery lab first. There is no reliable home repair that can distinguish a dead controller from damaged firmware or NAND when the drive will not enumerate anywhere.
Because the SSD is not detected in another device either, this is almost certainly a drive-level failure rather than a Windows, bootloader, or BIOS configuration problem. A failed controller, corrupted firmware or mapping data, NAND failure, or an electrical fault could all make an NVMe drive disappear completely. The BIOS screen alone cannot identify which one occurred.
The unexpected shutdown may have contributed, but the SSD could also have been failing first and caused the crash. Since the files matter, stop repeatedly powering the drive on and do not initialize, format, secure-erase, or update its firmware. A professional SSD data-recovery lab is the safest option. Recovery is not guaranteed, but a drive that is undetectable does not necessarily mean the NAND data is gone.
The low-battery warning while the charger was connected is unusual and should be investigated separately. Have the charger, charging port or USB-C power path, battery, and motherboard power circuitry checked before installing a replacement SSD. The laptop may have a power or adapter problem in addition to the failed drive.
It is still worth confirming that the SSD was fully seated and that the connector is undamaged, but since it was already removed, reseated, and tested in another machine, that possibility seems less likely. I would not keep cycling power just to see if it comes back.
