A HPG71 had water/liquid spilled on keyboard. The system does not boot. The keyboard does not have an sticky keys. Battery charges up and the battery charging light goes out when fully charged. All memory and HDA was removed and no visible damage. Re-assembled and tried to power up.

The power button lights up momentarily and the power (lightning) LED blinks three times. I did not find difinitive answers to the 3 blinks.

I am prepared to purchase a motherboard to repair but wonder if there are other things to check before that route.

Thanks for response.

I would check the CMOS battery, also completely dismantle Laptop and check for water, or corrosion

Post a link to the mfr. support page and manuals for the system. What does the documentation say about the LED blinking?

I previously posted about dealing with spills here. Let me know what happens after you follow the cleaning procedure there (only clean components that might have been wet). Since the keyboard may be difficult to clean, What happens when you run the system with the keyboard disconnected? Scott.

I checked the HP Forum and did not find a similar example. I did remove the keyboard and it did not change the response. I disassembled the laptop to see the motherboard. It appears that the water damaged a chip. There is a chip with the top burned/blown off. The heat/EMF shield is blackened by it. I believe the solution for this machine is a new motherboard. I have attached two photos, the front and back of the defective chip. I took the HDA out and used a USB - SATA adapter and was able to read the files.
