That's a very odd sentence and I can't really work out what, or if, you're asking.

Could you rephrase it please?

SOURCE: How do I disable double-click on an HP Pavilion dv4 touchpad?

Hi there Dublin. I recently bought a HP laptop myself, and I believe I can help your situation, or at least I hope I can. Here's what you do: Access your Control Panel>Click Mouse>Click Device Settings>Click Settings> Click Tapping> Click Disable Tapping. That should do the trick. You are not disabling your touch-pad, just the double-clicking that is associated with it. Drove me nuts for about a day, 'til I figured it out..Hope it worked for your notebook.

SOURCE: Failed intrenal power supply on HP Pavilion dv6700

Before you go thru all that, HP has an extended warranty for 6 and 9K units with Video and Power startup problems.
They have added an extra year to the original warranty and it would be to your benefit to check first.
Email customer care and issue a repair request.
You can chat with a tech and find out in no time yes or no.
If you log a issued complaint, they may review it in your favor.

SOURCE: hp pavilion dv4-1220us overheating then shutsdown

Sounds like you need to take it in for repairs, clean outs and/or replacements.

This product is known for it's heating issue and power consumption. Maybe the fan is starting to wear out and it's affecting the rest of the system. I would suggest checking the warranty on the system, if it is no longer valid, then I would look for a local tech in the newspaper.

Charger port not working.


I worked as a computer tech for 20+ years, and I still hate taking laptops apart. I strongly suggest you take it to someone who knows what they're doing, or you might end up with a useless pile of parts.

Pc no start.........


You might have a bad power supply. If you have a voltmeter, check the voltage of the standby power supply. This voltage is present even if the system is off, plugged in. It powers a small portion of the logic circuit. It should measure within a couple of tenths of exactly +5 volts. If it is low, or high, this will prevent turn-on. The purple wire of the 24 pin connector is what carries this to the motherboard. The color coding layout is found at http://pinouts.ru/Power/atx_v2_pinout.shtml If by chance this voltage is OK, then check the full on voltages also. Repair of the defective supply is probably by replacement of one or more small electrolytic capacitors in the appropriate circuit, especially if you are technically savvy. Capacitors are available through several suppliers; Digi-Key supplyies Panasonic FC series which are suitable for switching power supplies. Or, you may just replace the whole unit.
