Question about HP dv9620us Notebook

1 Answer

Starts and stops

The computer tries to powerup but then after about 5 seconds it shuts down, then it tries again. It will keep doing this. All the LED's light up but it's never on long enough for the screen to come on.

Assuming you are Windows based?

First disconnect all non essential devices, cords, internet connection, etc. Try rebooting normal. If that works try adding one thing at a time back to your computer, rebooting each time to test. If the initial test fails try rebooting in Safe mode.

If windows PC based, try booting to safe mode by tapping F8 as soon as the power is activated. Continue tapping until a menu should have Start in Safe Mode as a selection. If not find out the proper Start in Safe Mode for your OS. Safe mode operates your computer with the basics. If you can start in Safe Mode you might have a software issue. If you loaded something prior to failure, attempt to uninstall that software, or "Restore" your computer to a previous time.

If attempting to start in Safe Mode fails, attempt to start from a CD/DVD drive with a Windows Recovery disk or your original copy of the Windows program in your drive, (Normally your computer is set to first try downloading Windows from your Hard Drive. You have to go into you "boot menu" to change these directions. It varies by OS version but in most cases start tapping F12 on initial power up until you get a menu. You mouse is not usable. You must arrow up/down etc to move around. Depending on what you see concerning the "primary" drive or list of sequence of drives, you will more than likely see Hard drive or SATA. Write down what you have before changing anything. Change your primary boot up drive to be your CD/DVD drive and save your changes. Power off, insert your windows CD in your CD/DVD and power on. If windows boots up from your CD you probably have a bad or corrupted hard drive, or something in the associated circuitry, wiring? REMEMBER YOU HAVE CHANGED YOU BOOT MENU TO CD/DVD. YOU MIGHT NEED TO CHANGE IT BACK TO SATA OR YOUR HD DESIGNATION DEPENDING ON WHAT YOU DECIDE TO DO. It might be as easy as going to Fry's or another electronics place and purchasing a similar hard drive. Fairly easy to unplug, unscrew and replace. Watch for a "Master" "Slave" connector on the drive itself. Some of them had a little jumper. It has to be placed the same on your new drive. Of course if you replace the HD you will need to reload Windows first .(make sure you have a key code for windows) Then all your other drivers, and software. You will not have any of your old files unless you are able to retrieve them from the old drive. That recovery process is something for someone with advanced technical skills....if it is even possible. If you don't possess the skills to remove and replace the HD, pay someone to do it. They will probably also reload any software at the same time for nearly the same price.

    Thank you for your suggestions. I ended up taking the entire thing apart, cleaning it, checking the components, and then put it back together while making sure all the connections were stable. It worked, and started, but there were hard drive errors. I used my Windows 7 disc and wiped the drive and did a complete clean install. Works like it used to! Thank you again.

SOURCE: Will not start up

If it's not beeping during the first start up then it's not POSTing.  Beep means everything connected to it seems to be functional ie PnP  
Try pulling out your memory and reseating it.   Try pulling out your battery for 5 minutes then plug in ac(without batt) and see if it will boot.  Try pulling your hard drive and reseat.  (access by covers on bottom...dont be scared. Touch something that's grounded just before you remove) If all this and still no full POST(with beep/s) then sounds like a new mobo or processor.

SOURCE: I have a HP Pavilion tx 1000. Blank screen, LED lights on.

Hello, seems like your sleep mode doesent work as it should. Try to download all windows updates and look for a fix on microsoft sites.
But the best solution is to inactive the sleep mode setting and use the Hibernate options(if you want a fast start) but I suggest that you turn off windows with shutdown, its the safest and best way to have your computer to work properly.

To inactivate sleep mode.
windows xp
go control panel and power options
Change the system standby to never.
also choose power schemes battery, and change the system standby to never.
also the harddisk to never.
This should solve your problem.

To activate Hibernate you need to click on hibernate tab and bock the square.
hibernate= saves all your work to harddrive to restart your computer where you left off.

sleep mode= saves your work to RAM memory=takes a little bit energy.

SOURCE: The computer starts up and then shuts down, then

First things to establish, if you are running from battery whether the laptop is charged, if you are running from AC whether the cable works properly. If both of these are ok, have you made any hardware changes recently? If so, check that the are securley installed and if so then remove if possible. Failing that there may be a problem with the power supply to the motherboard, something you may be able to address if you have an intermediate understanding of internal components.

SOURCE: I'm sure this is a


Could be a power issue.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.
