I have this Chromebook and the charger is missing. I bought a replacement 5.25V x 3A micro-USB charger for this unit but it doesn't fit. I have exhausted all search avenues using the details given below in the product label. I am completely stumped. The HP SKU, nor UPN is findable on your site and they don't give me many leads on the web. I have checked the specs and cannot find any definitive information on the port connector type. Micro-USB doesn't fit. It appears it might be USB-C but that doesn't seem correct either because that seems to be a newer type of connector that would be unlikely on an older product like this. What is the standard connector type name for this product? Is there a part number or spec for the charger product? I'd appreciate any help - I'm completely stumped on this one!
