I've been through a few chargers for my Laptop (a 2015 model 17" HP Envy i7), typically due to somebody stepping on the end of the charger cable. For quite a long time I had a strange problem with the Laptop that it would only charge while switched off, once switched on even if charged the charge would dissipate - both with the replacement cable I'd bought from Amazon and my wife's original HP cable for her laptop, on the status bar if you hover over the battery icon it says "plugged in - not charging" and the charge dissipates until it powers itself off due flat battery at which point the light changes to signify its started charging again. Sent the Laptop away for repairs earlier in the year and they said there was nothing wrong with it charging - because its a bigger Laptop it needs a higher Wattage charger than a normal one. Bought a replacement 90w charger and its been working great since.
But while I was away for my brother's wedding last weekend someone [either myself or my kids I'm guessing] has stepped on the charger and bent it. It kept charging the laptop for a while but had to fiddle with the charger to get the connection. But a few days later it stopped charging altogether. Figured that it was the charger that was broken so borrowed my wife's charger and it won't charge the laptop at all either - even when its turned off. The light to indicate charging status stays off altogether as if its just unplugged.
So I'm worried something has damaged the charger port on the laptop itself. Does anyone know of any simple tests or fixes for what could have gone wrong short of sending it away for repairs?
