Reportedly, HP is already aware of the situation and is offering replacement TouchPads to its customers. Those who have contacted the company's support team should be getting a refurbished unit, presumably with a stronger housing, in exchange for their defective tablet. On the other hand, those who have purchased their HP TouchPad at a retail store are said to be getting a brand new unit instead of a refurbished one, hopefully from a newer batch that would not cause any troubles.
If you happen to be an HP TouchPad owner yourself, you might want to check and see whether your device is having the same problem as well since some people were not even aware of the issue until they read about it online. Feel free to drop a comment below and let us know if everything is fine with your tablet.
