HP Pavilion dv7-1245dx Notebook - Answered Questions & Fixed issues

This sounds like you have a bad DC jack on your motherboard. This is one of the most common problems with laptops and can be caused by jarring the DC plug in or hitting it into something or simply from normal use. As a result the pins on the DC jack become loose and consequently do not provide a charge to the laptop and battery. Wiggling the plug can make the loose pins contact sometimes which would explain why it "sometimes" works when you unplug it and plug it back in. Of course if this is the case then your battery is mostly out of power and that is why it powers off after a couple seconds. This repair costs between $150-300 from a professional repair shop and I would not recommend trying it yourself unless you've had experience soldering DC jacks
Another issue could be the CPU fan/heat skin if this is failing or the CPU is overheating the laptop will power off.
Please comment if you need further assistance

does the PC run good , battery out, and only on AC, it must. does it?

1. bad battery
2. bad power pack 19vdc 65w
3. or bad charger chip in the PC.

did you give it 24 hours to charge.

randomly run your fingers on your keyboard to loosen any stuck keys than restart again.

go to setup and change priority to HDD.

Try removing the battery and switching on the laptop with charger only.

There is a reset option that is supposed to help if the KB doesn't work.. yours is random or sporadic but this might help: http://hp.dezide.com/ts/start.jsp?guide=NotebookKeyboardandTouchPadorClickPad.net&as=true&SFS=sdoc§ion=ccweb&language=english&lc=en&cc=us&action=step&response=0&step=C39975.C39953&session=89f43caa-ba00-4809-80e8-eed31a

go to control panel -> system and security -> system -> device manager. that has a list of all the hardware on the computer, look for any items that have X ! or ? next to them. Could be that you don't have a driver loaded for that device.

Are you Install voice control any software on your computer. cheek your control plan apps list.Are its automatically install uninstall them.

You need to get into the BIOS screen and set the boot order so that the CD drive boots first. Then it will boot to the cd and tell you the same thing. That the hard disk has failed and cannot be found.

From the description of the problem, this seems to be a driver issue. What Operating system are you using?

Hi there! asking for keyboard lights! some of the solutions for ur problem are: 1. use external laptop keyboard with lights that are available in nearby PC store or electronics store else u may try it on online stores that may even offer deals. 2.Use USB light that illuminates light on keyboards that are more cheaper than keyboard replacement 3.If you are a DIY enthusiast and have hobby, and known knowledge of electronics try making LED illuminare from Ur laptop usb dongle out it may hav 4 pins say positive, negative, data positive and data negative and it supply around 5V supply with 1 amp current. try it may cost more cheaper than two solutions as i said above. 4. use low power bed lamp that focus on ur laptop keys. thats all bro! Have a nice day! bye! any question : [email protected]

another method I have used that works is to remove CMOS batt as you have done before - do not replace it yet though.Power on the dv7 without the battery in then off by holding down the button until it switches off.Remove AC power hold down power button 5 secs to dissipate power and replace CMOS batt,plug in AC and test.Hopefully it clears the bios settings for you

Check power settings,display will dim on battery power by default.Settings for display brightness are adjustable for AC and battery power.

It can probably be a missing driver issue however you can fix this issue by downloading appropriate driver from your machine`s manufacturer website and then re install it.

look it up on youtube
