my code will bold text around checkbox.
if you want to change style of checkbox then create 2 style class and apply conditionally using php

checked is simular as disabled
so use

<td>
<input name="power" type="checkbox" disabled="disabled"
<?php if($row['power_backup']=='on') echo 'checked="checked"'; ?> />
</td>
