Power Button Cable May Be Misaligned
On the Inspiron 530, 530s, 531, 531s and Vostro 201 desktops, the power button cable may be misaligned in its connection on the system board. When the power button cable is misaligned, pins might be exposed that the head of the cable should cover. The state that the system is in because of the misaligned power button cable may be misinterpreted as a "No Video" situation, as the system has no video, and the power button LED on the tower remains solid blue.
To resolve this issue, reseat the power button cable so that it covers all of the pins. After reseating the power button cable properly, the system displays CMOS checksum error - Defaults loaded at POST. To resolve this issue, set the correct date and time in the BIOS.
Determine If the Power Button Cable Is Properly Aligned
|Before you perform any of the following steps, read the Precautionary Measures warning (located in the Resources section) for your personal safety and to prevent damage to the computer system from electrostatic discharge.|
Power off the computer.
Unplug the power cord from the back of the computer.
Remove the computer cover or side panel to access the internal system components.
Verify the power button cable is aligned properly. (Figures 1 and 2)
If the power button cable is not properly aligned, unplug it and plug it back in to ensure all pins are covered by the cable head.
Set the Correct Date and Time
To set the correct date and time in System Setup (BIOS), perform the following steps:
Restart the computer.
At the Dell logo screen, press the <F2> key to enter the BIOS.
Press the <Down> arrow key to highlight Standard CMOS Features and press the <Enter> key.
Press the <Left> and <Right> arrow keys to change between month, day and year or hour, minute and second.
Press the <Up> and <Down> arrow keys to select the Date and Time fields.
Press the <Page Up> and <Page Down> keys to select the correct value for the field that is selected.
Once the correct Date and Time are configured, press the <Esc> key.
Use the <Right> and <Down> arrow keys to select Save & Exit and press the <Enter> key.
At the SAVE to CMOS and EXIT (Y/N)? message, press the <Y> key and then press the <Enter> key to restart the system.
