I understand your new computer is not waking correctly from sleep mode and you are requiring assistance with the issue. I would be happy to assist you, but first I would encourage you to post your product number for your computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number we can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
