I have an HP Omnibook that suddenly stopped recognizing its charger. Before I could troubleshoot the issue, the battery drained completely. I contacted HP support and followed their suggestions, but ultimately, I had to send the laptop in for repairs. They claimed the damage was customer induced and refused to cover it. Unfortunately, I accidentally included a damaged charger when I sent it in, thinking I needed to return the original power cable, which I hadn't used for a few weeks. Now, they're insisting that the damaged cable caused the motherboard to short out, but when I asked for evidence, they said there was no visible damage to the motherboard. How accurate is their diagnosis? It just doesn't seem right to me.

It's possible for hidden issues to occur, like blown fuses or damaged traces that you can’t see. It's not uncommon for a faulty charger to create problems over time, even after it’s been unused for a bit. It might not seem fair, but some damage is subtle and can manifest later on.

But could that really happen weeks after I stopped using it? That seems a bit far-fetched.
