You have a few posts and without a power up you can't reset.
"Samsung Galaxy Tab 2 s/n CE0168 Wi Fi tab will not power up."
I don't know your skill level but for me I test if my charger+cable is working then consider opening it up to disconnect the battery for a minute. There are YouTubes on that but as always, your choice on that.
How do I reset my Samsung Galaxy Tab 2?
