Does this have any corrosion?

Hi @generalramm ,

There’s nothing really obvious but then again there’s a lot a reflected light in the images so it is a bit hard to see even when zoomed in.

To be safe gently disconnect the battery from the motherboard (you don’t have to remove the battery, just disconnect it) and then check for any wetness still left anywhere inside the laptop. There is always power available at some places on the motherboard even if the laptop is turned off. The Power On/Off button is not a power isolating button. Its function is to signal the BIOS what the user wants to happen i.e. turn on, turn off etc. Think of the laptop as being in an extremely low power state when off and not that is is totally disconnected from any power.

Where was the liquid spilled onto the laptop (you didn’t mention) and also how long ago did this occur? If on the keyboard then you may find out once you go to use it again. If you have problems with the keyboard then try using a USB keyboard to check if it works OK and if it does then try replacing the laptop keyboard as usually when trying to fix keyboards you can create more problems than what you originally had.

Here’s the maintenance and service guide for the laptop. Go to p.21 and p.45 to find the HP part numbers for the various country specific keyboards available for the model. Once you have worked out the part number for your particular model variant search online using the part number only to find suppliers that suit you best. You may be able to verify the part number as sometimes is it found on the underside of the keyboard

If you can’t see any evidence of wetness or corrosion then allow the motherboard to dry out completely for at least24 hours in a warm dry place, (not an oven) before reconnecting the battery and reassembling the laptop.
