No worries. Check these steps located here for a tablet device. I'm not sure if your device is a laptop or tablet or combo but it is worth a try. If it is a laptop, there definitely should be a label on it, if it is easy enough to remove the battery, may be worth checking under the battery but first check the link that I sent to see if it can be found via the menu mentioned. Regards Joel
