The battery may be defective. The connections inside the laptop is the battery may be defective. The charger is maybe defective. None of them can easily be diagnosed with tools home and would require a reputable repair shop and/or certified to check.

HP 15 laptop: wifi does not work windows 8.1
I have Windows installed pro 8.1. I was using wifi on this laptop, it worked fine. However, recently, I see that the Wifi does not work although he shows me the SSID of my network I used to use and also the SSID of the networks of neighbors. (It means that the wifi on laptop chip is capable of scanning the wifi signals and so it works). The same router from which all other Mobile tablets, my home laptop work are able to connect to the wifi network. Only on this laptop I am facing this problem. What may be a solution or what I should try. I tried the steps listed here http://www.fixedbyvonnie.com/2013/10/how-to-fix-limited-or-no-connectivity-wi-fi-issues-in-windows-8...
Although I have not changed the default settings only steps above on blog, I tried to solve the problem. However, it did not work. Also keys function + F12 on laptop has no effect. The light on the F12 key is always on. However, it is possible to toggle the wifi in the bar of Windows 8.1 charms.
What should I check?
I bought an external USB wifi device that solved the problem. The card wifi on laptop works well, but for some unknown reason, he is not able to connect to home wifi router. http://www.snapdeal.com/product/leoxsys-150-Mbps-Nano-WiFi/1179610?utm_source=earth_feed&utm_campaign=TopPerformersPLAScaling3000&utm_medium=CPC&utm_content=1179610&utm_term=, & campaignid = 350311165 & 28373951005 = adgroupid & adposition = 1o1 & network = g & device = c & targetid = pla-55251503741

Re: Satellite C660 - 1 M 0 - battery does not work long
I have a new Satellite C660 - 1 M 0, and after using it for a week, the battery does not as long as compared to the first time that I used it.
I heard that a charge of initial battery life of 8 hours is required before the 1st use. Is this true?
Hi richardvdoran,
The battery time depends on usage and what you do. For example if you run a large number of programs and work with a high CPU utilization low autonomy and requires AC adapter / CC soon. Also surf the Internet needs battery power.
You can improve the battery life if you use the eco mode power plan. This will reduce the brightness and other things to improve the battery life.
First battery charge time may be 8 hours but that's different and according to other things.

My readers Optiarc DVD - RW AD-7530 ATA Device DVD/CD-ROM & the Bison Webcam built into my laptop. Does not work after I upgraded from Vista home premium to Windows 7 Home premium.
Although of course, the CD-ROM drive worked during the upgrade.
I noticed that when I turn firstly on the laptop, the last two lines of the front entry from Windows 7 are the following.
PXE - E6i:Media Test Failure, Check Cable
PXE - MOF: Exit PXE Rom
During the audit of each Properties in Device Manager devices", I learned that they both work correctly. In the list in the printers and the @Devices the only Webcam shown is also a "USB 2.0 Camera"
Can someone help me please?
Best regards
JohnBesides what abdelhak says:
The message of PXE boot that you receive when you start your computer has nothing to do with your CD/DVD-Rom drive. Your computer uses a PXE boot method to attempt to load Windows from a location on your network. Since you do not have this configuration, it is safe to ignore it. If it slows down the startup time of your system, contact your manufacturer and ask them for instructions on how to "disable PXE Network Boot of the BIOS.
Hope this helps,
Thank you! Ryan Thieman

On another PC I want to save my favorites, but my browser Firefox does not work how can I make the backup, before I reinstall Firefox.
Firefox cannot renew its tabs and now won't run and let me do a backupThis may be considered to be solve my problem.
I decided to uninstall the rogue program Firefox download and reinstall the same version (No. 8). I used Windows XP Add Remove programs who asked if I wanted to save the settings of Firefox until I uninstalled Firefox. I said yes and operated with the uninstall. I couldn't find a Firefox 8 so I went for the 12 version and installed on the laptop. This version 12 now works with all the passwords one favorite of the uninstalled 8.
Thank you for all your help and advice. -
Laptop quick launch mute my computer Pavilion dv6-1050us button does not work properly. He puts the speakers muted, but does not change color. It's still orange, not mater if your speakers are on or off. His other (white) State works because it is white to start windows, but then goes to orange and does not change when selected but by selecting the button speaker turn the speakers on and outside as it should.
I've loaded and reinstalled the quick launch driver software (sp46731.exe), but the problem is still there. The problem is about 2 weeks old. Have not added any new software that I know. But computer installs updates as received.
SimonHello
First download the audio driver by using the links below and save the installer to your desktop.
Once the download is complete, right-click on the Setup program and select "Run as Administrator" to launch the installation - ignore the warnings that you can see everything that is an earlier version. Once the installation is complete, restart the laptop.
Kind regards

If your USB modem is provided by your ISP, check for an Ethernet RJ45 port. If the modem doesn't, connect a RJ45 connection between the modem and the computer cable and UNPLUG the USB cable. Your computer should now connect to the Internet without any problem...

Single-pass does not work for Web sites after the last update of firefox
Single-pass does not work for Web sites after the last update of firefox. This works in IE and Chrome and it works under windows (when starting the computer), but not with any website in Firefox.
Firefox 30 spent some less commonly used "Always turned on" plugins "asking to activate. To check and change this to SimplePass, you can use the page modules. Either:
- CTRL + SHIFT + a
- "3-bar" menu button (or tools) > Add-ons
In the left column, click on Plugins. Then on the right, check the control on the right side of the SimplePass.
You may need to exit Firefox and start it again before it takes effect.
A little luck?
