The official charger and lead HP supply with the Touchpad allows higher than usual charge voltage, sometimes just using a mobile phone charger that has a lower charge rate will if left for 48 hours trickle charge enough to reboot the device and push it into a proper charging cycle. Once the HP logo appears on your Touchpad, quickly plug it into the charger supplied by HP. So you can kickstart it by repeatedly plugging your Touchpad into a laptop or desktop USB, waiting until it recognises the device, leave it a few seconds, then unplugging, and repeating this process up to 50 times, allowing a little charge to stack up each time. Due to some very odd decisions by HP, the Touchpad will not accept a full charge once it is depleted because the charging software requires a certain amount of power to get itself going, but it takes a few seconds to decide that this is the case. If this doesn’t get any response, it’s likely you have a discharged battery so try one of these charging tricks. The first thing to try is a hard reboot, press the Power button, the Home button and the Volume Up button all at the same time and keep them pressed for about 10 seconds. There are a few simple tricks that may resurrect your Touchpad if you have had this issue: There was a time when Ebay was full of bricked Touchpads due to users, having sat them on charge for a few weeks, presumed it was dead forever. Many users find that after some time, when their Touchpad battery reaches low levels, it refuses to charge and eventually turns itself off never to light up again. One known issue is Touchpad’s failing to boot up when the battery is depleted.
