I flashed my bios on HP Probook 6545b with the newest bios version which i found on HP support download page for this model. I successfully finished flashing procedure but my laptop is now dead. Battery led is permanently blue with orange flash on every second. Does anybody knows if it is possible to do some low level bios recovery !?

Are there any caps lock or num lock led's blinking?
Try removing the battery, see if you can get a post screen.
If this does not work remove the main battery, remove AC power, locate the cmos battery and remove it for 15 minutes, replace the cmos (RTC) battery and plug in AC power, see if it boots.
See this manual to show how to find the RTC battery, its under "Removal and Replacement" then "Service Tag">RTC Battery
Let me know if you get a bios post screen with an error.

Only other thing I can suggest is to re-seat all the hardware like memory modules, hard drive, dvd drive, but it sounds like a failed bios flash, and a bad one.
Usually only a motherboard replacement will fix a hard failed bios flash, unless someone else knows a solution.
Or it is a coincidence and something about the AC adapter or charging circuit failed, doubtful but possible.

I too have a 6545b that I tried to update the Bios. Mine hung after it tried to update it. Now it too just has a couple blinking lights and nothing. No post or anything. Did you find a fix for yours?? Mines a paper weight!
