Spilled some water, now touchscreen and keyboard problems.

[Kero]

Was a bit slow with drying / shaking out water. More and more keys started to behave strangely, until the device went into an infinite boot sequence.
At home I removed all keys, but there really wasn't much to dry.

Several hours later, the device booted normally. Unfortunately, some keys have ceased working (q, a, 4, 6, right arrow and enter).
When I press one of them, nothing happens. Strangely enough, pressing a working key after that, does not work once or twice, but then works normally.

As far as I can see, no damage to the keyboard electronic foil (that thin layer immediately below the rubber mat); chances are the point where the connector(?) is, top right of the kbd, got wet.

Worse; when swiping over the touchscreen, I still trigger an infinite boot loop (yikes! not even sure how that is possible! when the boot sequence otherwise seems normal)

Any insights helpful....

Seems touch was coincidence. But stuck in infinite loop now. Don't even know how to get a normal boot. Right now I'm wondering how I got a few normal boots, at all...

ESC permanently ''pressed' (or shorted, more likely) or some such thing?

If I close the device, it sits waiting in some bootloader menu. When I open it, I see so. I can move the selection with arrow down, but arrow up (not working otherwise) produces a screen with some yellow thingy image and "unknown". Allthough I have the option of Power Off, I cannot press enter to accept it, as the enter key no longer works. After 10 seconds or so, it then reboots.

Whether showing menu with lid closed, or in inifinte boot loop when the lid is open, the device eats battery and warms up. Must keep it connected to the charger. Wish I could at least shut it off when I go to sleep or leave the house.
