If you laptop is not powering up, try troubleshooting the usual suspects.


1. Is it out of juice? Plug it into the wall and let it charge.


2. If the battery micro controller has malfunctioned, try removing the battery and plugging the laptop directly into the wall.


3. Is the power cable shorted or dead? If you know a friend or family member with the same or similar laptop, you might try using their power cable to rule out yours being the culprit.


4. Adjustment errors happen sometimes. If you laptop has a brightness level for the screen on the keyboard, it might be turned all the way down. Try turning it up while on to see if anything changes.


5. Listen carefully to the laptop and observe any noises it makes while trying to boot it up. If you hear the happy sounds of electrical current running throughout the system, your problem just got more complicated.


6. If it boots but you see nothing on screen, it may be a dead or dying LCD. If it flickers at all, it could either be a shotty power/video cable link OR the LCD is done and needs to be replaced.


It could be anything, just troubleshoot it like a boss. Also, give me more information next time other than "not working."

You can sometimes you can use Win 7 drivers for the audio, found on the HP website: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?os=4062&lc=en&cc=us&dlc=en&sw_lang=&product=3837660#N231 ,for your onexant High-Definition SmartAudio 221 . That said, you may have to change the compatibility of the driver to WINdows 8, you did not say 32 or 64, and install it to your audio device. Have you notices other devices in Device Manager that are not working properly? I had a similar situation, Audio, Modem, Card Reader, when I upgraded an old (2005) Gateway MX6421 to Win 7 pro N 64 I had to locate the drivers, (from a HP site), change a few lines of code in the drivers and change compatibility to Win 7.

It's a commom problem when you upgrade to a new OS, Win 8. You have to find the Win 8 drivers. Is that the only thing? In Device Manager, search for hardware changes, locate Win 8 drivers at ASUS website.

Cannot adjust brightness in windows 8


Your laptop button functionality will not work until you install the drivers necessary. Check online for the drivers and make sure that all of your drivers are installed in device manager. To get to device manager, right click computer and click manage. In the sidebar, go to device manager. I'm not quite sure if windows 8 has a software slider... it should be under power options where you can adjust the screen brightness to save battery. Good luck
