HP Elite Book
Don't know spec or serial number.
The initial problem of the system:
-Cooling fan runs continuously at a high speed
-The screen display is blank
-CAPS lock, Wireless, mute button LED Blinks.
And system could only shutdown after long pressing the power button for 9 seconds.
Preceding this was an event of a spilled drink into the system, and deposits on the system board.
Technician cleaned and serviced the board and, after connecting to a power source, system showed no power.
Few days after, I reconnected the system to a power source and the screen came on to a POST Error message (without pressing the power button).
These is the POST Error message: "The system time is invalid. This may be a result of a loss in battery power. Set the correct time and date using your operating system. If this message persist you may need to replace the onboard battery.
Real- Time Clock Power loss (005)
Enter Reboot system

Currently, none of the keyboard keys are responding and the power button isn't responding even after the 9 seconds long press.
Please what should I do?
- (I'm not certain the technician might know what to do from this point)
Thank you.
