hello, all. when i was playing games, my HP Pavilion dm4 laptop screen turned black. one of my friends told me that i should replace the battery. He said that he met the same problem with me. i would like to buy one from a online shop, because it is much cheaper. i have found two, but i do not know which shop is better. can you give some advice? thanks in advance.

Hello
I tried to use my laptop on battery this morning but it wouldn't work. I am using Windows 7 and the icon box says
(10% available, plugged in but not charging)
Laptop works fine when plugged in to mauns.
I have had a look in the Control Panel but can't find any means of checking the Dell Studio 1440n Battery. http://www.deal-battery.com/dell-studio-1440n.html
Although I very seldom work the laptop on battery, when I go to bed I usually put the laptop in Sleep mode, instead of cloosing down so presumably the laptop is using battery overnight to have the necessary power required in the Sleep mode. I switch off at the mains power plug.
I have been following this practice fairly consistantly for about 6 months or so, but occasionaly closing down completely.
May I assume that the battery is knackered? It was new when I purchased the new laptop last year.
Is there a way to check the condition of the battery, or whether there is a charging problem with the laptop?
