I have hp pavillion DV6-6c35dx black screen with caps lock blinking twice to indicate corrupted bios. How do I flash the bios on this laptop?


If that computer wont boot to a screen that you can recognize, it is a brick. When the bios is corrupted and it wont allow the machine to start you cannot access any screens that will allow you to recover. It takes special equipment to flash the BIOS when this happens and most places just replace the whole motherboard because this equipment is not used often by repair shops.

Laptop wont boot up, black screen, has power


You didn't post the Make, Model of Laptop or the OS you are using. I'll use a Win 7 solution. Boot the Laptop, open the Control Panel, select Power Options, set to High Performance, select Change Plan Settings, set SLEEP to Never, select Change Advanced Power settings, go through the settings , set SLEEP and Hibernate to Never, Power buttons and Lid to shut down. Always shut down and unplug your laptop when not in use to prevent damage from power surges and possible Fire hazard IF the battery malfunctions. A reboot every day will reset the computer.

This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008. On startup, you may see a blank screen. If the diagnostic utilities detect a specific problem with hardware components, the fan turns on, but the screen remains blank. To help identify the cause of the problem, various LED lights on the keyboard blink a series of codes. The diagnostic utilities use the LEDs near the Num Lock or Caps Lock keys to blink a series of error codes. At the end of the series the blinking stops. The pattern of blinks will occur any time you attempt to start the computer until the error is resolved. Battery power LED blinks The Battery power LED indicates the condition of the power supply. When starting the computer, or when the computer is in operation, use the chart to identify the power condition. Battery Power LED Component Tested Error Condition Battery power LED off, and Caps Lock/Num Lock off Battery or AC Adapter AC adapter not connected or failure

Battery low charge or failure Battery power LED blinking Battery Insufficient charge on the battery When new computer is used for first time, the white LED light for the AC power connector blinks. Battery is still in "Shipping Mode", the light continues to blink even when AC power is connected.

To resolve, turn off notebook, connect AC power and allow battery to charge for at least 30 minutes, then start computer. LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help.
