    Can you describe what does happen. Any beeps on power on? Fan or hard disk spin? Why did you change the power supply and ram?

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 dv6636nr boot problem

When we talk about laptop won't boot up it is a hardware failure.

First of all, most of the hardware failures that are going to be presented in this article require you to disassemble the laptop and work on its internal components. Because of this, you need the required components to take the laptop apart (such as screwdrivers, etc.) and space, lots of space. If you don't have a workbench, then working on that large table in the living room should do it.

Second of all, you need to be extra careful about ESD (electrostatic discharge). Sure, this is important when working with a desktop system too, but you really shouldn't consider this as some sort of overreaction or waste of time. A few anti-static conductive bags should suffice. These are going to be useful when you take apart components from the laptop and you need a safe place to put them down.

If the laptop does not power on using the batteries, then try to power it using the AC adapter. Pay attention and see whether the LED on the laptop lights up, signaling that the adapter was detected. If yes, then your power jack works. If the notebook still does not power on, disassemble the laptop and remove the batteries. Look first for the CMOS battery and take it out.

Your best bet is that the problem is memory-related. What you need to do is re-seat the memory modules. If there are more than one, then try swapping them between each other and try different slots. Try booting again. If it does not work, then try running with only one module - this way, you can tell whether one is faulty.

Disassemble the laptop and remove the HDD, CD/DVD drives, and the modem and/or wireless card(s). If possible, take out the sound card module (if separate). To minimize the possible causes, you may disconnect the LCD panel as well. Try running this way. If it does boot, then try connecting each connector one at a time, booting up in between to localize the problem.

Good luck and take time to do a hard troubleshooting this trouble is not easy as well. You need to be care full in removing the some parts so that the other will not affected and being damaged.

Green power supply light is flashing so power is getting to the computer, however the computer will not start from start button. Have removed case and tried ***** start button. Didn't work. Comput


Power getting to the computer/Power Supply?
Yeah.

Power Supply good? -> NO

A) IF ALL of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.

Can use up to 89 Watts of power.

Your Power Supply doesn't even have enough power to spin fans, much less start the Processor.

Want to test the Power Supply? Have a multimeter?
No? Have a power supply you can borrow for a test unit?
KNOWN to be good, and Compatible?

if all fan are spin up.
see your RAM, maybe its broken.
a computer need a routine checking all RAM, if its not good, your computer will freeze.
try pull out and put it again. if its doesn't work. replace it.

I have no display even at start it doesn't turn on my monitor


Hi Anthony,
Does the PC actually start up? In other words do the front panel lights come on and can you see the power supply fan turn at the rear where you plug in your power cable?

If so, try removing the RAM memory from the motherboard, clean the connectors with some surgical spirits or anti-static spray, then replace the RAM firmly back in their slots and try turning on your PC again.

Let me know if you still have a problem after following this procedure.
Best wishes,

If you saying "doesn't always boot", most common would be motherboard...
If your motherboard still beeps, then probably some other components has the problem like RAM, GPU card etc., depends on your motherboard.

Hope that give an idea...

Hp pavilion.


You could have RAM problems.
Reseat the RAM module/s, they may not be making proper connection. If this doen't work you may have faulty RAM. Take them out and test them in another laptop or get your friendly computer shop to test them for you.

I have a hp pavilion 513c it wont boot up! the


Hello,

There are only two ways this can go for you.

One- you need a new power supply

OR

Two, you need a new mother board

You can verify the power supply by checking it on another machine

If the power suppy is good

And you do not hear the bios beep- then you are looking at a new motherboard- I would double check the powersupply first- most stores that sell them will let you check before you buy a new powersupply.

Lappy is dead mon.


question: have you replaced the RAM by yourself??? do you get the problem before or after the replacement?

if you get the problem after replacement your RAM probably have static groundings... it was get from not demagnitizing your hands and tools before installing a RAM... if you still got the old RAM... clean the contact points and the RAM socket first and test the old RAM to your unit... if you stop having problems just return your 2gb RAM and ask for a replacement...
