My HP dv2400 laptop is not working. It is just over a year old. When I turn it on, the backlights on the keyboard turn on, and the hard drive sounds like it runs, but the screen stays black.

When I turn on my 4 year old HP Compaq dc7600 the monitor never receives a signal. All cables are pluged in and working. Help!!!


One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive
Test the leads that attach to your ((hard drive from the motherboard)) or replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your ((motherboard to hard drive))
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error


hope this helps

Does not boot makes a clicking sound


You have a key stuck on the keyboard. Unplug your keyboard turn the computer on if it it gets past the post, then you need to find which key is stuck. If the keyboard is usb then you can plug it in when you free the key. If it is PS2 style you can shut off power right after it starts with out clicking. Once off key freed you can turn it back on. If key is not findable replace keyboard. After verifing no keyboard no clicking.

Failing Laptop Cmos battery and need bigger HD


As a general rule of thumb , the CMOS battery can be found underneath the keyboard. The keyboard can generally be removed by inserting a screwdriver into the thing gap at each side at the top and then gently lifting the meyboard up. Be careful with the cables connecting the keyboard to the motherboard though!

I cannot find a removal guide for the hard drive. However , look for a slot or cover on the side of the laptop , similar in size to your cd drive. Then turn the laptop up side down and unscrew one of the screws thats somewhere near the slot or cover , remove the cover and slide the drive out, If you can get the cover off but not get the drive to slide out , try unscrewing another screw as most laptops have a few screws holding the cover on and another to release the drive.

HP DV 2000 keyboard not responding on all keys. Laptop is 2 years old. Tried all usual remedies including keyboard replacement. Works on a USB plug in keyboard. Any ideas please


If a section of keys isn't working at all, you'll likely need a new keyboard.  If the problem is with IOPUJKL:M keys you may have the Numlock on.

Broken HP Pavillon dV6000


Explain, (endured a hit). Electrical or physical?
For the hard drive (a clicking sound means a spindle problem). Suggest you get a new drive if it's no longer under warranty. Once you install a new drive you can slave your old bad drive into the system & pull your data off it before it stops working.

As for the laptop it's better off with a pro.

Copyright 2007 by Morris Rosenthal -All Rights Reserved contact info How to replace a Notebook Keyboard and Mouse with USB Adapter When your laptop keyboard fails, you can usually buy a replacement for somewhere between $60 and $120, but putting it in is a real bear, and given the current prcies laptops have fallen to, it's tough to justify as well. When you own the same notebook computer for as long as I have, the pointing device, be it a pad or an intellipoint thingy, is going to fail. Laptop keyboard life is also somewhat limited compared to regular keyboards, hair winding around the works is a big problem, but I'd hate to encorage folks with limited mechanical skills to go prying off their keys because it takes some skill to get them back on. So, most notebooks have a PS/2 port to allow for an external mouse or keyboard, but few have both. You can try a PS/2 splitter if you can find one, but the more elegant solution is a USB to PS/2 adaper, shown at right. usb1.jpg USB Keyboard and Mouse Adapter
usb2.jpg Computer End of USB Cable
The USB to PS/2 adapter comes equipped with a standard USB input, the rectangular shaped connector (left). The other end sports two PS/2 ports, green and purple, green is for mouse, purple is for keyboard. You don't have to use them both at the same time, but for a notebook with a failing keyboard and pointer (Ahem) it's a good solution. Windows has had native support for USB mice and keyboards at least as far back as Windows 98, I wouldn't bet on '95 as all the USB support was sketchy. The point is, as long as you're using WIndows 98 or later, you don't need any special software with the USB to PS/2 adapter. So, what's the big deal about installing a USB adapter that I did a whole page about it? Try it when the laptop CD drive has failed:-) The CD drive on my notebook went south over a year ago and I never got around to replacing it because I figured with a failing keyboard and mouse, I should be looking for a new notebook. The solution is to actually install the USB to PS/2 adapter on another PC with the same version of Windows. Then, install it on the notebook, and every time Windows looks for a driver on the CD that doesn't work, point it to the A: drive instead, go to the other PC and copy the reqired file onto a floppy, and do sneaker net. It may have taken 20 minutes, but it's a once in a lifetime job, so it was worth it.

Don't replace anything without troubleshooting first! Thinking about doing this for a living?
In case you're wondering, if you want to install real software, as in programs that won't fit on a floppy, onto a notebook with a dead CD drive, you can buy an external USB CD for much cheaper than a replacment drive for the notebook. Installing the software from the USB CD can be just as much fun as above, unless they provide the drive on a floppy, you'll have to install the software on another PC with the same OS first and then bring the required files over one at a time as Windows asks for them. You can use a Jump Drive instead of a floppy, though it's the same amount of work. BTW, I know I use laptop and notebook unterchangably, it's habitual, not intentional:-)

Good Luck, Please dont for get to Vote.Thank You.
