So, my Ma bought a laptop about 2 years ago. It is a HP Oman model Hp-15-ce018dx. It comes with a charger, part number 917649-850. The charger died last week. I can find the charger on HP's website, but it is on backorder. She went of the local Office Max and bought a Universal charger for it, but it will only charge the laptop when it is turned off. She then bought one off Newegg Marketplace, and they did the big switcheroo and sent her a different HP charger that has the same ratings. It will not charge the laptop at all. WE are in the process of getting that refunded. all the chargers I find for it are not the 917649-850 charger, even though they are listed as being a 917649-850 charger. If you look at the fine print, it is a different, older charger, or the reviews are saying they got a different charger. I think it may be one of those "smart" chargers that the laptop talks to when you plug it in to make sure it is a genuine HP 917649-850 charger and it will not work if it is not a genuine Hp 917649-850. Any ideas?
