Computer: HP Elitebook 8460p
Sys: Win 10 64 bit

Out of the blue one row of keys (9,O,L, and period) quit working. I blew the keyboard out with compressed air and they worked for a bit, then they quit again. Nothing got spilled on them. Is there a chance the laptop got hot enough to melt some solder connections? It runs pretty hot if I have a game or video going (have a cooling pad on the way). Seen lots of possible problems/ solutions online, but wanted an opinion before I proceed with one.

Solder melts at 188 °C (370 °F), so there's little chance of that happening without major damage to other components in the laptop.

Have you removed each key and physically cleaned under it with a qtip? Thats a specific row of keys. When you press them do they feel like a normal key, stuck key, or a soft key?

It could the keyboard cable connection to the motherboard causing this. Try re-seating the cable into the connector, the video shows how to do that.

If that doesn't help you will either have to use an external Usb keyboard or get a new laptop keyboard.

Or, use the onscreen keyboard for certain keys. (If you carry the laptop around and don't want to carry an extra keyboard).
