Question about HP Compaq 6730s Notebook

2 Answers

Left computer running with charger connected. Screen went blank and light showing power connected was no longer lit. New charger did not solve it. New battery (with some charge) worked. Still no charge so new battery now flat! Both chargers will light up the peripheral light on the jack socket when computer power switch held down. Tried disconnecting battery and external power and holding down power switch (to discharge any memory?) but still nothing. Any ideas?

Many facts missing
does work with no battery now, IT MUST
turn on the PC, notebook old , does power stay on? yes/no.?
when you turn it on does the display work at all in any fashion
even just short text ?
like it did new? "hit, Esc"? to enter setup or BIOS"
BIOS is the 2nd test, does BIOS work now, on line power no battery
IT MUST WORK , is this easy?yes.
if the screen is dead,
the Power pack is bad, or you bought the wrong one.
The power pack is just that, AC to DC Power;.
the charger is a chip deep inside the PC, on the main mobo.
if the BIOS is dead with a good power pack then you have major inside case problems.
Ill list them. (BIOS DEAD no matter what)
1: shorted things plugged it killing the power bus.
2: regulators inside bad, on MOBO.
3: line jack to power pack broken to the power jack at the edge of mobo to power pack. (resolder it? ask a tech to?)
4: or worse there is ALWAYS worse possible. even bad mOBO
5: bad ram try each 1 by 1, to see if one is ok?
6: CPU overheats an shuts down fast (2 causes, lint there or heatsink failures 2 ways, ask.
7: modules inside LT shorted, see them all in the book at HP.?
those. My HP lap has 6 modules inside that can fail an short.

so knowing all that ,why not pay a tech to do his/'her job
or take a class on PC repair, A+ Certifications. yah.

If your charger is working properly and the laptop is as well, then the laptop should work without a battery in it at all. If your new battery worked and laptop worked with it until the battery died, then the charger or charge port is damaged.

If it does not work with charger plugged in without a battery, then your charger(s) or the laptop charge port itself may be damage or broken. Or worse, the laptop may be dead.

If the laptop does nothing even with a good battery with charge (no fans, no boot, nothing on-screen, no noises) you're laptop could be dead; likely a burned motherboard or processor. It may have overheated or something along those lines.

SOURCE: Blank/Black Laptop screen on HP DV-6000 notebook

Your symptoms sound like a known issue with the dv6000 series of HP laptops. Rather than go into a lot of detail here, let me just refer you to the HP web page about the problem. If it fits your situation, call HP at the special number shown on the page. They've been replacing motherboards even for units more than a year old. My son just got his back yesterday, and so far so good. I hope this helps.

SOURCE: Won't recognize battery charger

The battery might need to be replaced.  If it works plugged in, but is not charging....it is simply not holding the charge.  I know it seems strange that when it is plugged in without the battery it will not work, but that sometimes is the case.

Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

SOURCE: black screen on booting my Compaq 610 notebook

If it seems like you're accessing the hard drive (drive light comes on, flickers intermittently, then goes off, it's a good chance your screen is bad.

First thing to do is plug in an external monitor and start up the laptop. If it comes up with windows, you know it's the screen.

To find out if it's the backlight, or the lcd, toggle the monitor function and shine a flashlight on a slight angle to the screen. If you can faintly see what was displayed on the external monitor, then the backlight inverter is probably bad.

If the external monitor didn't come up, you're probably looking at a motherboard.

The good thing is that all of those are covered for one year under Compaq's warranty, on a new machine.

If you are able to use the external monitor, back up your data, because HP/Compaq usually reformat the harddrive. Additionally, if you've added memory, pull the cards. They want it sent back the way it came from the factory.

Sounds like you need to calibrate the battery, it is supposed to be done every 3 months. If it is not done, your battery will display the same symptoms are you describe. Yes, this holds true for adding a new battery also.

Here is HP's instructions on how to do it. You want to scroll down to the section called "Calibrate the notebook PC battery".

Bring your laptop under sunlight. If you look very closely and can see your screen then your backlight went out. Otherwise there might be a loose/broken connection to your lcd.

I had to buy a new in car charger for my navman s30,but when i plug it in to the sat nav & cigerette socket it keeps showing a computer,usb & navman picture.


  • Turn the Navman off by holding the power button in the upper left corner of the device until the screen goes blank.
  • Plug the unit into its charger using the USB port on the bottom of the unit. The battery indicator light next to the power switch should turn orange, indicating that the device is charging. Once the light has turned green the charge is complete. If the light does not turn on, verify that the car charger is plugged into a working outlet.

There are 4 reasons why your unit is behaving this way:
1. Charger is the problem.
2. The docking station is the broken.
3. The battery is broken or not accepting charge.
4. The actual unit is the problem.
It is very hard to tell which one is causing this to happen.
Let us do some troubleshooting first:
1. Plug your charger in an A/C outlet and make sure the red power light (left) is lit, otherwise the charger or the docking station is broken.
2. You can test the charger with a multimeter. Unplug the charger from the docking station and measure the voltage across the outside and inside, it should register more than 5 volts DC. If there is a 5Volt DC the docking station is the problem otherwise the charger is broken.
3. If the red power light is lit and the status light (right) is lit too, your docking station is broken.
4. If the red power light is lit, dock the unit into the charger, the status light (left) should turn red when your battery is accepting charge or turn blue when your battery is fully charged.
5. If the status light will not lit at all (while the red power light is on), tap the screen while the unit is docked on the charger. If the unit will become alive, you need a new battery otherwise you need a new unit.

12 hours is very long time to charge, the status light should turn to blue in less than 2 hours especially for a new battery.
