HP DV6700 Power Problem

Hi,
I have HP DV6700 which I bought 4 months back. It has Vista, 3GB RAM etc. Recently I am having an issue with this one and I hope you guys can help me. It has stopped starting without AC power. When I start it with AC Power all the blue lights switches on but laptop does not start. After 20-30 mins (some time more) I switch it off and restarts again then it starts properly. So far as I don't encounter any issues after my laptop is ON but I do see that System date has gone back to Apr 2007.
I contacted HP customer center and they asked me to drain power and reinstall BIOS but it did not help.

Thanks for the help.

 

your battery is ok ?

 

Hmm...

Well, what they offered as a solution would have been the first step I would have said to do. The next thing if the problem persists would be to check to see if the CMOS battery is damaged or dying. In case you don't know, the CMOS battery is generally a small flat style medical battery like what is normally found in a key fob or garage door opener that provides a very small charge to the ROM memory of the motherboard which stores your systems information such as the time as well as the initial boot sequence that is referenced to start your hardware in the system as well as tell it to acess your hard drive and run what ever O.S. you have installed. Although it is rare, the CMOS battery, if not performing correctly, could cause a mis-boot where not everything hardware loads or does not load in the correct order causing stop errors to occur and essentially hang the system before it even reaches the windows operating system. Also, as I have already pointed out earlier, it can be responsible for the date always reverting back to the original system saved date.

If you are comfortable with opening your laptop, then you can use the HP technical bulletin guides in the support section of the HP website to look up and follow directions to gain access and check the battery. If you are not comfortable with doing this, you are still well within your standard warranty and can easily contact HP to send the laptop off for them to diagnose and repair.

Otherwise, the only other thing I could think of to do would be to try a O.S. repair/reinstall with your recovery discs to see if a nasty or something got in and or corrupted something in the boot sequence.

Best of luck to ya.

Could be the battery bug:

Take out the battery pack and unplug the AC power

Hold the power button for 30 seconds or more

Try starting up with only the AC power

 

Thank You Guys, I removed battery and ac power and hold the power button for 20-30 secs. For the first time in a week it started with battery power. I really feel my battery is dying but HP Quick check says its in good condition. I prefer working with AC power on most of the time. Does it reduces battery life.
Thanks again for quick response.

 

The battery cells itself isnt dying. Its just a glitch that happens time to time

 

If you run the system the majority of the time plugged in at a specific location, then yes, it would be a wise idea to remove the battery. The notebook will still run fine, but when the battery is in there, it is still running electricity through it even if you are plugged in to the wall. So, it is still working your charge cycle life which can lead to premature failure of the battery.

I had the same exact problem with my dv6700z notebook. HP claimed it was the motherboard and heatsink fan....I thought that was super retarded but I sent it in for repair and it did not fix the problem hence the upgraded dv5t replacement that they are sending me because I had to send my dv6700 out THREE FREAKIN TIMES!!!. I suggest that you still send it out for repair since you have only owned it for such a short period of time.

 

Thanks jreezy86,

The last thing I want to do is to send my laptop back to HP. I use it a lot so won't be able to live without it for long. You needed to sent thrice also freaks me out. I don't find any issue once my laptop is On so will see how long it lasts.
It started happening again so just hanging on..
Thanks HP for all these....
