do you have the battery installed when running the T510 with the ac adapter?

i do not work with battery.i open antivirus scan,two cpu test program and watch a hd film than my cpu increase 1.2 to 1.5.After i close hd film, cpu again 1.2 ghz.
Hence the problem you have, Thinkpads throttle down without the battery installed. If you put your battery in, and do the same test then the problem of CPU throttling should go away.
Also, which adapter are you using? 65 or 90 watt?

in the previous thinkpad laptops the throttling problem goes away with a 90 watt adapter installed, but i am not sure whether this is case for the latest thinkpads.
Just leave the battery in, and you would be okay. Make sure you set the charging threshold appropriately under Thinkpad Power Manager. i.e. start charging when the battery level drops below 50% and stop charging 95%.
P.S. If the battery is faulty, it would fail regardless of whether you use it only a few times and leave it uninstalled, and the problem could be exacerbated by the fact that it fails just after 1 year battery warranty.
Your battery can also act as the UPS, should power fail due to either blackout or brownout.
