Both case buttons shut down computer...no sleep option on either

I retired my XP machine and switched the XP's better case with my other Win 7 Pro 64 bit system. ( Win 7 had an older case with less usb ports/options/cooling etc )

AOK except with power buttons...both buttons shut down PC...no sleep for either button. I have sleep enabled for the "sleep" button on case front...but both buttons shut down system. The 2 buttons are as follows: left button has a 'triangle' on it...right button has a 90% circle with a small vertical line at top.
No longer have the info for the case...and no 'brand' is stamped anywhere I can find on the case.

Sleep worked before on the XP system with the right/circle button...but both buttons now shut down PC ?

Thanks...TiminAZ

By convention, the "90% circle with a small vertical line at top" is the universal symbol for POWER (or the ON/OFF switch). The wire leads from this switch (2) should be connected to the motherboard's PWR connectors - which I am sure it was since the XP days.

In your Windows Power Options there will be a setting that will allow you to select what you want to happen when you press certain buttons. For the POWER button the default is "Shut Down". This can be changed to Sleep or Hybernate. Users choice.

To access settings, go to Start > Control Panel > Power Options
Then for what ever Power Plan is selected > click "Change Plan Settings"
Near the bottom of the next window, click "Change Advanced Power Settings"
Click the plus sign next to "Power Buttons and Lid" > and make your selections.

I am not familiar with the "'triangle' on it" button. But let's assume it is a "Sleep Button", and you can change that too in the same place.
