Laptops have an option to turn off the wireless, you basically have to turn on your laptop and hold the FN key and look for your key that has a little atenna with signals and press that together with the FN key, you should be good, if that doesnt work then check your device settings and make sure something didnt disable your wireless card.

My computer wont puck up any wireless connections it doesnt even show the adapter anymore i don't know what happened can anyone help??


Could be an error with the wireless assistant or maybe a corrupt wifi driver. The following link is for the HP wireless assistant, try downloading and installing it:

This is the link for HP support where you can try downloading a new wifi driver. You will need to know what wifi adapter is installed to get the correct driver:

I am having trouble connecting to the internet because my WLAN has been turned off, how do I turn my wireless back on?


From the HP website:

The power to the wireless network and bluetooth devices is controlled by a switch or button on most computers. It is possible to accidentally bump the button and turn off the wireless service. c02230159.jpg On most computers, there is an LED light that glows blue when the wireless device is turned on and enabled, and glows orange when off or disabled. Some newer models use different a different color scheme. To turn on and enable the wireless device, do the following:
  1. To turn on the wireless device, simply move the switch to the on position. On some computers, the switch is actually a touch point on the panel above the keyboard.
  2. To enable the wireless device, right-click the HP Wireless Assistant (disabled) icon c02228164.gif and select Open Wireless Assistant . Click Turn On . The HP Wireless Assistant (enabled) icon c02228163.gif will display.

Please backup all you files to a dvd or external hard drive and run system restore back to factory default settings.

After backing up the documents, restart system and hold down f11 key till you hear a beep then follow the prompt.

I cant enable my wireless adapter


First, check if the blue light or green light for your network adaptor is turned on. This color light means it is working properly. If it is red, or no lights, it is not working properly.

try checking if your wireless network adaptor's driver is corrupted.

go to "my computer", then right click to go to "properties", then go to the "hardware" tab, then "driver manager". There, look under network adaptor and check if that driver is functioning properly by right clicking it and then "properties".

If it IS corrupted, re-install it here:

Hope this helps! ^_^

Hp dv4000 screen turned pink now black


If its not the backlight inverter or cable. It will be the LCD screen itself. It seems the shop you took it to isn't really up on laptop repair, as this is a common issue I see often. Get on Ebay and find a screen for your model and replace it. I asure you this will fix your problem.

DV4000 cant connect to wireless network


HP bought several motherboards from the same company in China. These boards work for about 15 months then they can't find the wireless card. This is caused by a defect in the North Bridge chip overheating over time. This chip is not replaceable at the local level. You can send it back to HP for a replacement and sometimes they will charge you $300 - $500, or you can just replace the motherboard yourself. Check with them first since there is an ungoing lawsuit regarding these boards. Either way the only fix is to replace the motherboard. This is also a problem for the dv6000 and the dv9000 models. HP knows that 30% of these will fail.

Mike
