A/C Control Panel problem

I have a 2011 Sportage. Recently the battery went flat and after jump starting it, I noticed a problem with the A/C Control Panel. Sometimes on ignition start, the panel remained off, and sometimes the panel was illuminated but buttons did not work. After running the engine for approx. 15 minutes, full A/C functions automatically came on. Is this a problem related to the battery or the A/C Control Panel ?
