Question about HP NB199UA Pavilion Notebook

3 Answers

My HP pavilion dv4-2145dx won't boot! I've tried hard resets, power downs, even disassembled, carefully cleaned, and reassembled to no avail. the lights on the LED power strip come on but the screen remains black ( tried function f4, tried connecting to external monitor, no good.) Oddly enough perhaps one out of every hundred or so times i start it up it will begin to boot only to glitch and go black screen after a few moments. I suspect software corruption since when it does begin booting i can get to the safe mode prompt page at least. anyone out there have any ideas????? please!!

Motherboard is defective & needs to be replaced with a new one.
You can find a replacement motherboard by searching on e-bay.com with the motherboard's model number. This could be found under the RAM.

How to Disassemble an HP Pavilion DV6000


The HP Pavilion DV6000 is one in a popular line of consumer-oriented laptops produced by HP. Relatively inexpensive, the Pavilion DV6000 is a good all-around value for most users. Taking apart an HP Pavilion DV6000 is not an easy chore and if you plan to use the laptop again, it is important you know what you are doing or you have a large appetite for risk. If the above doesn’t describe you, consider taking the HP in for professional repair or upgrade. Otherwise, follow the steps below to disassemble the HP Pavilion DV6000.
18385245_1.jpg?w=200 1、Prepare a clear workstation. Turn off the laptop and remove all power components including the cord and the battery. (Turn the laptop over and you will find the tab to push and pop out the dv6000 battery.) Also remove any peripheral attachments like card readers and USB devices.
90-04208-003_original-hp-pavilion-dv8000z.jpg?w=250 2、Turn the HP Pavilion dv6000 upside down and unscrew all the screws you find. Try to keep them separate by size so you can put them back in the same spot when and if you decide to reassemble the laptop.
3、Remove the hard drive and memory modules by pulling up on the rectangular compartments. The memory is located in the central compartment (remove by spreading latches and pulling up), and in most HP models the hard drive is located to one side.
4、Remove the optical CD/DVD drive by pulling on the drive face to the left and out of the laptop. Remove the WiFi card by disconnecting the gold connectors on the antenna and pulling the card from its slot.
5、Turn the hp dv6000 back over and remove the keyboard and power panel/media touch pad. Carefully pry the power panel up with a piece of hard plastic near the power button on the left side. Be careful when pulling not to yank the power connection as you might accidentally rip out a wire. Pull back the keyboard to reveal the connections. Disconnect the connections by carefully pulling on the tabs with your thumb and forefinger. If they are tight, wiggle them back and forth while pulling on them to loosen them.
6、Remove the screws that were underneath the power pack/media touch pad. Carefully pry up the top casing and set it aside.
7、Detach all visible connections to the motherboard by pulling gently on them, wiggling them if they are stuck. Gently pull up from the right side of the motherboard and remove. The HP laptop is now fully disassembled.

Hp laptop has blinking red square above touch pad, comp. won't allow for reboot or restoring to factory conditions


If you do an illegal shut down which is power off by holding down the power switch for 8 seconds. The HP computer will then boot with the scandisk program, which will restore your hdd to perfection. Windows XP or later now use 'system restore' to rearrange registry from a previous calender date that the computer used to work perfectly.

Hi,

If the battery of the HP laptop is not in a good condition, sometimes booting problems might happen. To remove any static charges accumulated in the battery, you would have to remove the battery and press the Power button for about 25-35 seconds. Then reset the battery. Even after this, if your laptop is not booting up then you could perform the battery calibration and press F8 key to boot in safe mode.

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.
