Click Start Control Panel and go into the Power Options to check the Battery Meter. Batteries on last for so long. Maybe it's time you buy a new one.

If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

Battery charging


Check your charger to make sure it is the right one for your laptop. If it is then test it's output to make sure it is producing the correct voltage and amperage. You can read the label on the charger to find out what it should be. Then a simple test with a multimeter will tell you what you want to know. If that is all good, check the contacts where the battery plugs in. Are they in good shape? Not bent or broken. Clean them with a pencil eraser so they are shiny. Now, disconnect the charger and plug in your battery. Do you have an indicator of power? Will your laptop boot? If not, use the multimeter to test the output of the battery. It should read the same output voltage as the charger.

Eveytime i charge my laptop, it automatically shut down, reboot and even hang,


Possible cause:

1. Power adapter failure.
2. Motherboard failure.

Possible troubleshooting steps and repair solution:

First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.

If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

HP Pavilion dv9910us Entertainment PC Internet Problems Hello. Internet Service Provider: Comcast OS: Windows Vista Router Used: Netgear Security: WPA Duration of Problem: 4 months This problem has been persistent ever since I purchased my HP Pavilion dv9910us Entertainment PC (August 3, 2008). Summary: I was able to access ALL Internet sites wirelessly at home via Firefox (my preferred Internet browser) for two weeks after I bought it. Then (for whatever reason), I could only access SOME Internet sites wirelessly via Firefox (such as sciencedaily.com, acc.edu, google.com). I could not access sites like Wikipedia, answers.com, Youtube, etc. Once I hooked the laptop directly to the router, I could access all Internet sites again. That eventually stopped working and, in essence, I can't access the Internet as efficiently as I'd like to at home. Now, when I try to access a Internet site like del.icio.us, it will attempt to load the page forever until you manually stop it. It never says "Cannot Access Site" or "Internet Time Reset" or whatever. It is simply a blank white page with the words "Loading..." on the top. However, if I access a site like sciencedaily.com, it'll go straight to the page as fast as possible. Notes: My uncle, my aunt, and my father were all able to access all Internet sites with iPhones and laptops without problem. It is only my laptop that is having problem having access to all Internet sites. I have no problem whatsoever logging on to my home and other wireless networks. For instance, I can access my school's network easily and have access to all Internet sites (with the exception of those blocked by a filter). My laptop indicates that I am, indeed, accessed to the Internet even at home. It has nothing to do with Java or Javascript. My uncle and I both enabled and disabled it to test whether it had any effect. It didn't. It has nothing to do with a specific browser. My uncle and I used both Internet Explorer and Mozilla Firefox. It made no difference; the results were the same. My brother attempted to re-enter all the numbers (ISP, DNS, etc.). For some reason, Vista makes it difficult for you to manually do such things. I believe he mentioned something about a problem with the DNS. Then again, I'm not sure. The laptop is recognized as a connected computer when I review the Gateway Summary. My laptop is also listed on the DMZ (Demilitarized Zone) and Wireless Process Filter. Solution: I hope to God someone can address this problem. I'm in college, and I don't have time to spend 6 hours working with this laptop. I can't send it to a technician either considering I have to have it for class. Please help!!
