Question about Computers & Internet

1 Answer

After turning on my computer all seems OK until it seems for no reason the monitor goes blank and will not re-open by pressing any key. The small green light in the right hand corner flashes continually. Sometimes by moving the cable at the back slightly it will function again, but screen goes off again after about 10 mins or so.

I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

My monitor shuts down after one second.


Dell monitors automatically go into power-save mode after a preset amount of time when the computer is inactive. The Dell monitor will go completely black, instead of showing a screensaver. This doesn't mean that your Dell computermag-glass_10x10.gif has shut down. Instead, this allows your monitor to essentially turn off until it's needed again. You can change how long it is before the Dell monitor goes into power-save mode by changing your display settings.
  1. Step 1 Press any key on your keyboard or move your mouse. Either will turn off power-save mode. Alternately, you can press the power button on your Dell computer tower or laptop.
  2. Step 2 Press any key a second time if the monitor goes from power-save to stand-by mode. Stand-by mode allows the screensaver to appear.
  3. Step 3 Enter your user name and password into the login prompt if your computer requires a login. Press "Enter" to begin using your Dell computer.
  4. Step 4 Change the display settings on your Dell monitor to prevent your monitor from going into power-save mode prematurely. Right-click anywhere on your desktop and choose "Properties." Click the "Screensaver" tab and press "Power." Beside "Turn off Monitor," choose a time amount from the drop-down list and press "Apply."

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

Sounds like the pc power supply is bad... U can replace it, but if supply went out it may have damaged the motherboard. In future, have monitor blank off automaticlly and install UPS to supply pc. HP has histroy of weak power supplies.
