Dell Studio 1555 Laptop: Diagnostic Error Codes 3600:0533 and 3600:0852

Hello,

I have Dell Studio 1555 Laptop, when I connect the AC adapter the battery LED blinks orange, orange, orange, orange and white. I run the Dell Pre-boot Diagnostic Test and found these two error codes

Error Code: 3600-0533
Msg: Primary_Battery_Bay - Unable to communicate with battery

Error Code: 3600-0852
Msg: Primary_Battery_Bay - A permanent failure was detected

I also run the online Dell diagnostic and got this Error code: WBT02-LPK

Anyone has any idea about these error codes. Any advice would be highly appreciated.

Khan.
