Hi lessskill,
Welcome to Sony Community!
What are you trying to do? you mean the tabs are missing? May I know the complete model name of your laptop?
- Do a power cycle = unplug the unit > remove the battery > press the power button for 15-20 mins > put the battery back > turn on the unit.
- Go to BIOS and check
- Go to Sony website and check if there is a BIOS update available for your laptop.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
I hope this helps
Regards,
Jen
