Error Caused By HP Technical Support

I purchased a second-hand HP 2-in-1 touchscreen tablet PC online. The device was functioning well in terms of overall performance; however, when switched to tablet mode, the touchscreen failed to activate. In order to clarify the issue and find a solution, I contacted HP technical support. I had a remote session with a support agent that lasted approximately 40 minutes. Unfortunately, following this intervention, the device became completely non-functional. The support team informed me that the device was no longer under warranty and provided me with a list of authorized service centers. Before sending the device, I was specifically instructed not to perform any interventions and to send the unit exactly as it was. I complied with this instruction and sent the device to the recommended service center. Their diagnosis was that the motherboard was faulty and that a costly repair was required. Following this development, I reached out to HP customer service again. This time, however, I was told that the device may have had a defect from the beginning, and more surprisingly, that I might have caused damage through "static electricity." This claim was baseless and technically inaccurate. As someone with a basic understanding of such issues, I know that a static discharge capable of damaging internal components would require the device to be opened and special equipment to be used—neither of which occurred. The only intervention made was through HP's own remote support. To summarize: my device was working before HP’s remote support session. It was their incorrect intervention that rendered the device completely inoperable. Despite this, responsibility has been denied, and no concrete steps have been taken to resolve the issue. It is deeply disappointing that a global technology company like HP would adopt such an evasive, delaying, and accusatory approach instead of taking ownership of a problem clearly caused by its own technical support process.
