My girlfriend's HP Pavillion DV4 1000ea laptop has just crashed+wont start up. It is plugged into the mains. When i press the power buttom a white lightening bolt symbol flashes at the front of the laptop and a single white light flashes once on the laptop directly under the power cable and the laptop will not start up.
I have taken the battery+power cable out+pressed the power button for a minute and tried again but still no luck.
Please can anyone suggest what the problem is?
Sorry for this-
I've looked to buy a replacement power cable from Amazon but am so confused as there seem to be lots on there, for example the power lead i have says 250 volts but this one here:
says 19 volts??
There seem to be so many different price ranges, from £14.99 to £60.
You need to check the output Volts on the old mains adapter, it sounds like it needs replacing. If you have a meter plug the adapter in and put the positive prod to centre of laptop end of out put lead and black to outer of plug to see if it putting out any DC volts check your meter for settings for DC volts before testing and set it to about 20 volts scale
