My office jet 5600-hp all in 1 bed time i leave ok but at morning dos,nt work by pressing 'on' button.adapter is ok.at removing power sourse slightly listing sound.

Step 1:
disconnect all external devices including battery & AC adapter
Press and hold the power button for 10 seconds to discharge any or all static from the PC.
Step 2:
Connect back the battery & AC adapter
press the windows key + B and at the same time press the power button.
This should clear the BIOS (Incase of BIOS issues or interrupted updates)

Try taking your battery completely out of the system. Plug your AC adapter in and power on. If this works, then your battery is bad. As long as you don't need to use it remotely you are ok. Otherwise, you will need to replace the battery. Hope this works for you.

Hello,
