Pavilion dv7, Windows 7 Home Premium 64 bit
At times (not every time) after shut down or getting put to sleep, fails to boot up. Screen stays black, fan is heard running and on the keyboard the led light on the caps lock key is slowly blinking. press the power button to shut down and then try to restart and it does the same. If i do this several times, it may finally boot normally and windows starts and functions as normal. On one of the restart tries i hit the esc key and it booted into a diagnostic screen. I used the HP start up tester and it came up with a failed error message on the section Fast DST (i believe that is what irt was). The error Faliure ID was as follows: PU0AKD-5H675W-XD0141-60VM03 (note in the first set of characters, the D may be a 0 zero)
Unknown if this has anything to do or if a separate issue.. But it does not keep any System Restores into memory to go back and use. When this failure to boot properly happens and then it finally boots, any past System Restores are gone, there are none at all to go back to. Thanks for any help or info on this.
