gee why not leave the bad battery out, and run on AC power
now. batteries short, leave it out. until PC runs again.
does it work now? on AC line power. ONLY ?
the laptop will run just like desktop now, endlessly (AC power ok)
next is the fan running, battery out? yes/no.
if yes, it has power maybe... some.
does the screen ever show text,? or HP logo.. small logo.
if yes that means you do have power, and the screen works
and the BIOS hot keys work : do they?
the hot keys are, F2 F10 , Esc, F8 or f11.

Hi,

What is the operating system of your laptop? Is it running Windows Vista or XP? Can you check if you're getting an IP address wirelessly?

Go to start>run>type cmd and then hit enter.

On the black screen type, ipconfig/all and see if you're getting an IP address similar to the IP address of the other working computers. If not, then that is the problem, that means that the wireless security that was entered on your new laptop is incorrect. To make sure that you entering the correct key, save your security key on a notepad and then copy and paste it on your wireless adapter settings.

pls configure first WAN setting WI FI AREA NETWORK,IP address connection from the router wi fi,subnet, and protocol.

Most probably its the problem with the autonet ip address where the computer picks a bad ip address. If your internet service provider has DHCP enabled you cannot put the manual IP address. If its a new problem try system restore, uninstalling and reinstalling networkdrivers. resetting winsock.(search google)

press F11 when turning on your PC

Looks like F11 might be your key.

i has to work, make sure that he security key its right. because one of the major problems of not been able to obtain IP address is because the WEP/WPA key or what ever type of security key you use is type incorrect. try re-typing your security key again and that should solve the problem.
