Ya know........Pavilion dv8 is a Series of Notebook PC's.
Encompasses a LOT of models in the series.
Have no idea of which LED in front you are referring to.
1) Test the AC adapter (Charger) with an economical multimeter. Average cost is $5 to $12. Set to DC Voltage, and check the output voltage of the AC adapter.
As far as I can tell the DV8 series uses 18.5 to 19 Volts. (DC) Use an AC adapter that is rated at 90 Watts, NOT 65 Watts; if using a replacement AC adapter.
The port on the laptop that the AC adapter plugs into is a DC Power Jack. (DC_IN) The plug end on the power cable from the AC adapter, and plugs into the DC Power Jack, has a Center Hole, and an outside cylindrical metal shell.
The Center Hole is the Positive connection. This is where the Positive (Red) probe lead of the multimeter goes. The outside cylindrical metal shell is the Negative connection. This is where the Negative (Black) probe lead of the multimeter touches.
Also have an assistant gently wiggle the power cord TO AC adapter; and power cable FROM AC adapter to laptop. Intermittent reading indicates a broken wire, or wires.
DC Power Jack LED lights up? Means nothing to me. I want to know the FULL DC Voltage is getting TO the laptop, and there are no breaks in the wires of the power cable, or power cord of AC adapter.
THEN AC adapter checks out.
2) AC adapter checks out? What condition is the DC Power Jack in? Battery removed, use the eraser end of a No.2 pencil, and GENTLY see if you can wiggle the Center Pin around.
ANY perceptible movement of the Center Pin, means replacement of the DC Power Jack. Fortunately for this series the DC Power Jack is connected to a cable with wires, and they end in a plug connector. Which plugs into the motherboard. It is now a DC Power Harness.
Should be on the motherboard, near where the Power Connector Cable plugs in. Rectangular shaped with 8 'legs'. ('Legs' are J-Leads)
Believe one or more to be the problem. Typed the rest above because it is a power flowchart, and when diagnosing always go through the steps. Would s-uck to replace a motherboard, when the problem was an AC adapter, it's power cord, or the DC Power Harness.
This is more on the subject, by using the HP pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; as examples,
had a similar problem,and I resoleved it via a bios flash..this allowed the hardware to be fully recognized and to perform the specified role.For some reason,the bios software for this version seems to corrupt after several years. I have had my machine for the last four years..until it recently started giving the issues,it had no problems.
Hi Vinman, the DV9600 series pavillion laptops mostly uses the same type of power adapter. these adapters can be purchased in local computer shops, or you may check on Radioshack, walmart, bestbuy or circuit city whoever is the nearest. if possible, bring the broken one with you so that you can personally compaer if you will get an original part, or a compatible part.
All lights come on HP Pavilion dv1000 but will not boot. looked at motherboard and by power connector there is a blown part the number on the board shows PD27. I need to know what thhe part is or a schematic showing
The first thing I would try is a USB wireless adapter. If this works it may be a hardware problem. If this does not work it is likely a software problem. Make sure the interfaces are not disabled in the connections window. Make sure you are using a good cable, test it elsewhere.
