Question about HP Pavilion dv4000 Notebook

1 Answer

For all those with a Flexed Chassis Freezing issue!

I've had the same issue. I've stripped it down twice looking for a solution only to have the same problem. My solution was to place two pens under the laptop (one on each side)near the area between the keyboard and touch pad. Then put one hand near the screen hinges and one hand near the front speakers and bent the laptop chassis back to OEM shape. I worked from one side to the other and haven't had any freezing problems since. You can get another motherboard but with a flexed chassis you'll always have the same issue. Hope this helps..

Download a program called paragon and unzip and follow instructions to create a boot disk and install program on it.once done with the created disk in drive turn on pc.the disk will boot up and a program will start to check or/and edit youre hd.
if it detects bad sectors(which is what seems to be your prob) repair them;bet way format entire hd.
this is probably the best software type for repairing difficult to fix hard drives .

Sounds like crappy solder on th gpu. Basically, you need to take a hair dryer to the GPU and reseat it. HP had this problem on a bunch of older DV models. Without knowing your model, I can't post specific instructions.

Supplies needed:
Thermal paste, I recommendArctic Silver as it has better heat transfer properties
Hair dryer
wooden spoon

Strip the chassis to the motherboard, pull the heatsink from the GPU and set the board on a heat resistant surface. Clean all old thermal paste from the GPU. Heat up the GPU with your hair dryer while using the wooden spoon to press down on it.. When you see the solder turn shiny, turn off the dryer. Continue to press down on the GPU until the solder changes back to a dull color. Let everything cool down before reassembly. During reassembly, make sure to clean the old thermal paste off the heatsink and reapply a fresh layer. Reassemble your laptop, and turn it on to see if the fix worked.

I know at one point there was a bad batch of solder that made its way onto assorted motherboards, so this fix may work for the same issue on many laptops. Good luck!

Hp pavilion dv4 2045dx keeps freezing and shutting down

It seems that you have a virus and it is running at boot.
first try to boot in safe mode and see if the computer stay up.
"Restart... hold the f8 key down until you see the boot option menu and select: "Safe Mode with Networking"If your pc still shut off and freezes then is not a virus and it is a hardware issue, possibly power issue or heating issue with the CPU.If it is ok in safe mode, then you need to remove the virus in safe mode. Download antivirus program that support safe mode operation.after successful removal of the viruses, reboot in normal mode and edit your msconfig, to remove any running programs that might be viruses.
If you continue to have a problem, I can log gin to your PC and fix it myself, just download teamviewer and contact meTony

Acer aspire laptop screen problem.looks like ink burst behind screen

Suggest you replace the LCD screen, pearlboslem. It is damaged.

If you post the Acer Aspire model number, I can find replacement LCD screens for your perusal, and should be able to find a Service Manual. (Free)
I will also guide you step by step the best I can.

This is on the Bottom of the laptop in a white Service Tag.

If you have never replaced an LCD screen in a laptop, the task may look daunting.
I assure you it isn't.

Generally the plastic strip that is above the Keyboard, and below the LCD screen, is removed.
Usually the Power On button, and LED indicator lights are in this plastic strip.
Different manufacturers have different names for this strip of plastic.
LED Cover, Power Button Cover, etc.

With a lot of Acer laptops the LCD screen can simply be accessed by removing the Display Bezel, and the plastic strip does not have to be removed.
(Some laptops do not have a plastic strip)

In the front of the LCD screen, and surrounding the LCD screen, is a thin plastic frame.
This is the Display Bezel.

Most display bezel's have rubber screw covers, going around the front of the bezel.
These are gently picked off with a computer pick, or suitable tool.
They have a type of rubber cement on them, and if careful, they can be reused.
(Stuck back into place)

The screws are just Philips head screws. Once removed the Bezel is slightly flexed, and popped off.

{The outside edges of the Bezel have tabs. Plastic protrusions formed out of the Bezel itself.
These tabs mate up with mating tabs in the Display Cover. The top cover of the laptop.

The tips of the fingers are put on an inside/middle edge of the Bezel, and used to gently ease this inside edge up a little. (Care is used so that fingernails do not touch/scratch the LCD screen)

With the inside/middle edge brought up enough to insert a second finger, the second finger slides down, and eases up on the inside edge again.

The tabs will start popping loose. The procedure is to keep moving along the inside edge with your finger tips, and keep popping the tabs loose. Once you are 1/2 way around, or so, the Bezel will pop free.

Some bezels do not have screws. The Bezel is flexed as above, so it is distorted, and the tabs pop free }

Once the Bezel is removed you are looking at the LCD screen, and how it is fastened to the Display Cover.

The LCD screen is an assembly. It is composed of layers. The layers are held in place by a screen frame. A thin metal frame that resembles a picture frame.

Usually on the left, and right side of the screen frame are metal brackets.
These are attached to the screen frame with two to four screws.
The screws are removed, and the LCD screen assembly is almost ready for removal.
There are cables (Wires) that have to be removed from the LCD screen, the Inverter at the bottom of the LCD screen, and maybe wireless antenna wires.

This gives you an idea on replacing an Acer LCD screen. Different models are shown.
Along with a pictorial guide, I may be able to find a Service Manual also,

At the end of every article for each laptop model, you will see in red -
Read the rest of the entry
Click on this for the full article on that model of laptop.

You can click on each photo shown to enlarge it.

Just to show you how relatively easy it is to replace an LCD screen, in an Acer laptop.

Post the Model Number, and I'll give you more exacting information.

Why does my laptop keep freezing? I use a free registry cleaner and ccleaner weekly,defrag regularly and have good anti virus and anti spy protection, I have loads of memory left but still freezes once or...

If the system has 2 memory modules, try them one at a time and see if the issues only occur with one module or the other. If the issue is isolated to 1 module, then replace it.

Other things to try, Update the system BIOS to most current version if not done already and most current video driver

New charger but no ac power to pc

A common problem is for the power jack connections on the system board to go bad. They break loose from the main board because the power plug gets flexed and then the power doesn't get from the adapter to the board. No power light (or intermittent flickering) and no battery charging results.

What you need to do (or have done) is to resolder the power jack onto the board. This isn't difficult, but it involves getting the main board out to reach the solder side. In some cases the board can be damaged because of the bad connections and isn't repairable. Then the board needs to be replaced. But most often the soldering fixes the trouble.
