I am having a problem with a hp pavilion dv4. When it is plugged in the charging light will flash when i try to power it on the other lights on the case flicker and die . and if i plug in the laptop without the battery the charge light doesn't flash but it will not boot. I have tested the: cable , cmos battery , and the internal power connector and they are all good. I have tried resetting by removing the battery the cmos battery and the charger and pressing the power button then reconnecting those parts .... still won't boot . I have tried to start it up with almost nothing besides the mother board the charger and the LCD ... still nothing. Is this the mother board ? Does any one know if this is a common problem with this model ?

I have a HP DV4 1114NR. When it powers on, all light come on but a black screen. THe power light and batt charge light flashes. How to resolve this and get it to boot up?


It could be forced into "Sleep Mode" by USB or other ancilliary devices. Ensure there is no CD/DVD in the drive, no Lan connection and no USB items, especially modems, plugged in and try again.

My hp pavillion dv4-1220us laptop, won't start up...I press the power button and it turns on for a couple seconds and then turns back off....


1) Is it the battery, power up using the power supply.

2) When the power supply is plugged in, is there a charge light/led (could by a bad power supply not charging or providing a good connection)

3) Is the CPU over heating? Check the vents underneath are they clogged with dust?

After this, you're getting into internal faulty component issues and need someone to look at it.

HP Pavilion dv9700t battery dead, faint blue flash from plug


Check your mains adapter plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.
