Press power button nothing comes up on screen, however, the num lock icon lights up and flashes, the caps lock icon also lights up. Dell Vostro 1510.


Copy and paste this link into your internet browser for the service manual for your laptop.
http://support.dell.com/support/edocs/systems/vos1510/en/SM/html/trouble.htm#wp1092170
The star icon (*) means flashing LED, the bold circle means on, the circle within a circle means off.
The LED's that they are referring to are the NUM, CAPS and SCROLL.
It appears that you have a problem with your LCD. Try connecting an external monitor to your laptop. If you get a display then your LCD display panel needs to be replaced. If no display then your motherboard needs to be replaced.

"HP Pavilion m7580" is not


Hello,

To verify whether it's a no POST issue, press NUM LOCK or CAPS LOCK key and check whether the CAPS LOCK or NUM LOCK lights are lit or changes when you press on it. If it doesn't then it's a No POST problem.

However, if the computer screen shows the HP logo or a display then it's POSTING and is experiencing a No BOOT issue.

If the NUM LOCK or CAPS LOCK responds when you press it but there is no display, check the connection between the monitor and the CHASSIS or CPU.

If you have verified that it's a No POST issue because CAPS lock is not responding, you need to open up the chassis to do a troubleshooting procedure. Be sure to unplug the chassis to all the connections especially the power cord. Drain the power by pressing and holding the power button from 8-10 seconds.

Here are the things that you need to do after you open up the chassis.
1. Reset the Memory sticks. Connect the CHassis to the power and monitor. If no go, try turning on the computer without the memory sticks. The aim of this troubleshooting is to see a display on the screen. Any display would be a good sign. If no go. Put the memory stick back in.

2. Remove the CD drive. Turn on the computer, check for development. If no go, proceed to step 3. Just leave the cd drive removed

3. Do the same thing with the other devices like the hard drive and other devices inside. Your aim is to see a display.

Let me know if what happens and I'll get back to you.

Once you see a display. Let me know by replying to this thread.

Power light comes on but not working


First you need to determine how many blinks you are getting when you try to power on the laptop. Check the blinking codes below and reason behind that for HP Compaq laptops Blinking battery power LED Battery Insufficient charge on the battery Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional Blink: 5 - Caps Lock/Num Lock - System board General system board failure Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure You need to first Remove the memory module (RAM)- Try to power on the laptop ? then again reset it and try to power on. Check whether it is coming on or not. try the same procedure with Hard drive. If laptop is getting power on after removing one of the device then we can be sure that that particular device is faulty and we can change that then? Let me know if you find any difficulties doing this.. I hope this will help you to get it work. Plz vote for me..Dreamkam

Blank screen on laptop


Sorry to hear you are having problems. I have had this same issue before with this particular model. The following solution works 90% of the time.Perform a hard reset as the first procedure.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Meaning of Sample Blink Codes for some EFI Notebooks Number of Blinks or Beeps Location of Blinking LEDs Component Being Checked Error Condition Continuous glow Battery power LED Battery The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook. 1 Caps Lock/Num Lock CPU CPU not functional 2 Caps Lock/Num Lock BIOS BIOS corruption failure 3 Caps Lock/Num Lock Memory Module error not functional 4 Caps Lock/Num Lock Graphics Graphics controller not functional 5 Caps Lock/Num Lock System board General system board failure 6 Caps Lock/Num Lock BIOS BIOS authentication failure Continuous blink AC power adapter LED Power adapter Insufficient power
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. Some HP Notebook PCs come with one stick of memory but have two memory slots. The problem could be that the stick of memory or one of the memory slots has a bad connection. The memory module compartment on most notebooks is located on the bottom of the case. The exact position varies by model. However, on some models, the memory compartment is under the keyboard. See your User Guide for the exact location of memory modules on your notebook.

Use the following steps to remove and reseat the memory modules: Step 1 - Remove the electrical power To remove all power from the computer and prevent accidental damage to the electronic components, do the following:
  1. Turn off the computer by pressing and holding down the Power button for about 30 seconds.
  2. Unplug the AC adaptor from the notebook.
  3. Slide and hold the battery release latch to the unlock position.
  4. Use your finger to lift the battery up and out.

  • Remove the memory module cover on the bottom of the notebook .Loosen the compartment's retention screws and lift up and remove the memory compartment cover. Remove the memory modules from the memory slots To prevent damage to the memory module, grasp the memory module by the side edges. Do not touch the metal contacts.
    1 - Pull the retention clips away from sides of the memory module
    2 - Gently pull the module out of the memory module slot
  • Reseat the memory module by holding module at a 45-degree angle, and pressing it firmly into the memory slot until it is seated.

    After reseating the memory module, replace the cover over the memory compartment before restarting the computer

    Hope this helps FiYa! If you find this solution helpful, please take a moment to leave us some feedback.

    Thank You!

    HP DV6110us: 4 beeps, no boot


    besides the beeps which indicate a motherboard timing issue. There should be LED blinking codes given on the front LEDs. I will include the blink codes below, but lets try to at least get the system up and running. First, I would like you to remove the RAM sticks from the laptop and just reseat one stick back in the machine. Try to boot with that one stick, if it does not, try the other alone. There have been issues when reseating the ram or re-installing it have temp. fixed the issue. If it does reboot, go to the HP support site, put in your model number of your laptop and download and install an updated BIOS. Below are the blink codes that may narrow down the problem.....

    HP DV6000 LED Blink Codes

    LED Component Error Condition
    Blinking battery power LED Battery Insufficient charge on the battery
    Blink: 1 - Caps Lock/Num Lock CPU CPU not functional
    Blink: 2 - Caps Lock/Num Lock BIOS BIOS corruption failure
    Blink: 3 - Caps Lock/Num Lock Memory Module error not functional
    Blink: 4 - Caps Lock/Num Lock Graphics Graphics controller not functional
    Blink: 5 - Caps Lock/Num Lock System board General system board failure
    Blink: 6 - Caps Lock/Num Lock BIOS BIOS authentication failure

    First check your num lock led if it on and off when you press num lock key then your cpu is ok.
    Then therer is issue with monitor to cpu loose connection

    Screen resolution problem.
    For that when you power up press F8 key then enter in enable vga mode.then go to control panel and dispaly then settings then change screeen resolution to 1024*768 then apply and ok.
    Aslo reconnect connection from monitor to cpu vga port.
    Also check in bios some times your harddisk is not detected proeprly.
    If problem still remains open cpu cabinet and reconnect data cable and power cable to harddisk.

    NO SIGNAL PROBLEM


    Please check whether the monitor is set to the correct settings. If you feel its incorrect, most LCD/TFT monitors come with an auto set up button which will restore the display to one that usually works. In case it still doesnt work, you might need to connect your pc to a different monitor and check the display settings. You could also try to download the drivers for this monitor and then re-connect the monitor and see if it works.
