My laptop screen is black and caps lock and scroll key are flashing

That is a security configuration on HP Laptops, depending on the way they blink is the problem your machine has.

Here is the web page where this info is posted, in case you need more info, hope this helps you to determain.
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

It sounds to me like the harddrive has errors on it. First, I would try completely reinstalling windows with the windows disk. If that does not solve the problem there are several pieces of software that are much stronger harddrive repair solutions than the built in Windows one. Try this one, it is free for 10 days. You will need another computer (friend's computer?) to download and burn this software onto a CD, then put the CD in your computer and boot to it by pressing any key when it asks you to.

I can't get my note book to start up in safe mode with networking it just keeps going to the tech guys screan and won't start in safe mode.


When your Advent laptop isn't booting properly, you probably have a problem with your startup disk. When the startup disk is acting up you may take it to a repair shop, or you may save a lot of money and fix it yourself. Windows 7 computers come with built-in software that will allow you to repair your startup disk in just a couple of minutes.

Start your computer and press down on the "F8" key. Click on the "Repair your computer" option in the "Advanced Boot Options" menu that appears on the screen.

Press the "Enter" key.Choose your keyboard layout on the next screen and click the "Next" button.

Click on the "Startup Repair" tool in the "System Recovery Options" screen.

Wait for the computer to repair the start-up disk

Try going to Safe Mode. Normally you press F8 when you start the computer. When in Safe Mode, click Start -> Run then type msconfig. On the first tab, click on Diagnostic Startup. Apply, close and reboot the computer to Normal Mode. Lockups during startup are caused by startup programs.
