Try other monitor to be sure that the problem is nothing to do with your system unit. If you do and very sure that the monitor is ok, turn off and unplug the unit first and remove the video card and insert the monitor cable to its onboard location and power up the system. if your system works then the problem is surely the video card. But if not, we have a deeper problem. If you cannot hear any beeps at all when you power up your computer then the problem could be on the major components. Try removing the memory modules and reseat them back one by one to see if one of them is the culprit before powering up the system. if this works, turn off your system again and insert back the video card and the monitor cable. if these never works at all try removing all memory modules and power up the system if you never hear any beeps at all pertaining that the system memory is not present it could be that you have a corrupt BIOS program or your motherboard is defective. Clear your BIOS by finding the jumper setting on the motherboard. Usually it is labelled CLR_CMOS. The default or normal position of the jumper is 1& 2. Clear the CMOS by taking the jumper to 2 & 3 position for about 10 seconds. Be sure that your system is unplug before doing this. After 10 seconds bring back the jumper to its normal 1& 2 position then power the system on. If these works please correct the system time by going to BIOS setting. If these never work at all. Don't jump to a conclusion that your motherboard or you memory modules or your processor may be defective. The power supply unit sometimes is one of the unforeseen component that emulates this trouble. So if you have a multitester (analog or digital), set the range to 50DC and place the black lead on any black wire connections and place the red lead on any yellow wire connections. When you power up the system the multitester should read a stable 12V on your meter any drop to about 2V or intermittent reading means your PSU is defective.

The Triangle may be the toner low light. On the older models it would look like a Triangle of stacked up cannon balls. I am not specifically familiar with your exact model.

Display is not coming , black screen is there


If you get zero display at all check if you can hook up an external monitor first to determine if problem is with screen or video card.
If display can barely be seen that is practically black but you can just see it in bright light check brightness levels of screen i cranking them up fails then you need a new screen backlight. Talk with hp about repair.

Display went from extremely dark to complely black


Hello there.
I understand that your Notebook is not showing the display lights. To isolate the issue please do the following troubleshooting steps.

1) Check the display with external monitor. If the external monitor is showing the display then the problem is with the LCD screen. If the external monitor is not showing the display then the problem is with the display card.

2) If you have any torch light or a cell phone , try focusing the light on the LCD screen after the Notebook is powered on and check whether you are able to see the texts and images on the LCD. If you are able to see the images and texts then it is the problem of the LCD back-lights. The lights which glow at the back of the LCD panel are not working.

If your Notebook is under warranty HP will repair it free of cost.

Contact HP customer chat center for more information regarding the details of the repair and the procedure for sending the Notebook to HP in case of repair.

For contacting HP chat support click on this link or copy and paste it in address bar of a web browser.
