Capslock10 times blink with both indiator num/scroll lock are off


It certainly does indicate motherboard issue, sub out the ram memory one at a time and test, if no change! the laptop needs to be checked out for motherboard problems.

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. Caps Lock/Num Lock LED Component Tested Error Condition LEDs blink 1 time CPU CPU not functional LEDs blink 2 times BIOS BIOS corruption failure LEDs blink 3 times Memory Module error not functional LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

My inspiron 1520 will not turn on. the power light will stay lit, and the capslock will blink like 45 times, and the nothing happens


Remove the battery as well as the adapter. Then plug back the power adapter only. Try to boot up with out the battery. If it worked your laptop crashed from hibernation or stand by. If not, BIOS might be affected and needs reset.
Hope this helps.

'why the ligth for the uppercase letter function flashing for 9 times and the dell d600 don t start


Hi,
basically the problem that you are having is a no P.O.S.T (power on self test ) issue or to make it clear the computer is having some problems turning on. Now, how is the capslock light related to the problem? For dell portables it uses Numlock, capslock and scroll lock key as diagnostic indicators as well. based on your discription, the off-flashing-off combination means that there is something wrong with the main board on your computer. and the badnews is the part costs a lot. you'd probably end up paying $400.00 for the parts and repair.

Hope this helps.

thanks.
