I got an hp dv4 for christmas '08 and i really love the portability of the computer, 14 inches is perfect, but its gaming capabilities are shot bc of the integrated graphics. My parents bought the laptop to surprise me, but they don't really know much about computers and thought it would be good for games. I am wondering is there any possible upgrade available that would be cheaper than getting a whole new laptop?
View 3 RepliesI'm looking to upgrade the CPU in my DV4 and have 2 questions.
1. Will the p7350 work in this machine? Seems like it should, only difference being the FSB is 1066MHZ as opposed to the T5800 which is 800mhz.
2. Has anyone actually taken their keyboard out? I'm a well seasoned tech and have repaired many laptops and even after following the repair manual from HP, I can't get the keyboard to come out.
System: HP Pavilion DV4-1125nr Notebook PC
Product#: FR922UAR#AB
System Board Id: 30F7
BIOS Version (before update): F.12
OS: Windows 7

I tried to upgrade the BIOS to F.55 which was provided by HP. After successfull installation of new BIOS windows shutdown properly. I start the PC again, HP Logo appears, and then nothing happen. The OS does not load or boot at all.

I also tried to boot using Windows 98 Second Edition CD (to load DOS) but this also did not work.

My laptop is HP Pavillion dv5-1125nr:
• AMD Turion™ X2 dual-core mobile processor RM-72 2.1GHz
• 4GB DDR2 memory • DL DVD±RW/CD-RW drive
• LightScribe labeling • 15.4" display
• 250GB hard drive • built-in webcam
• Windows Vista Home Premium 64-bit with SP1

When I use Windows Vista Home Premium 64 bit, I upgraged BIOS to F.20. Now, I want to downgrade to F.11 (for Windows XP), but I can not find this version.
Replacing/upgrading the CPU on an 8930 is not so difficult. With care, a small cross head and flat head screwdriver and some thermal grease the following procedure can be carried out in less than 20 minutes. The description here is for information only; if you choose to try it out bear in mind that things can still go wrong and you do it at your own risk.
The linked photos show my upgrade of a T6400 to a P8600.
A list of CPU benchmarks at NOTEBOOKCHECK shows the relative merits of these two (and other) CPUs. Whilst the P8600 is not cutting edge technology it is significantly better (in my mind) than the T6400. In addition (BIOS permitting) the P8600 also supports VT, hacking the BIOS is my next step; I have not covered it here as I have not done it yet and anyway others have already covered potential approaches Add to that the fact that I got a good deal on eBay (under 70 GBP) and you can see why I chose the P8600 above possible replacements. Most of my use is development and design so I do not need to be at the expensive cutting edge, but superior performance and hopefully virtualization are key for me. One interesting difference in the choice of CPU is that the FSB should increase from 800 to 1066MHz.So on to the CPU swap out...
First shutdown the notebook and disconnect the mains power adapter. Turn the notebook over so the base faces upwards with the screen hinge nearest.
Unlatch and remove the battery (1). Unscrew the 7 screws holding the access panel in place. If you are careful the screws can remain in their locations as the panel is removed to avoid needing to record where they each came from.
Carefully release the panel by lifting the edges gently releasing the internal clips, start at the recess (3) and work round both sides to the side opposite the recess. The side opposite the recess has lugs not clips and so this edge should be slid out when the others sides are all unclipped (like opening a door with the recess at (3) representing the handle and the opposite side the hinges).
Once released the panel comes away easily and completely, most force is required releasing the first few clips but this need not be excessive and can be helped with a well placed thumb nail.
From now on static discharge is an issue, make sure you are careful to avoid damaging your laptop. Tweezers may be useful as the screws are small, avoid dropping them as they could find there way further inside and become difficult to rescue............
Here is a link to flickr stream of Upgrade, [url] I made a video of it and once thru editing will post it...One thing in the photo stream you must undo all screws on the back, also on the top there are three hidden screws under the middle of the monitor covered with black stickers, just pierce with cross head...Also you need to run a rather large screwdriver down the right side of the body and bottom each side of the pad to release the plastic snaps ps familiarize yourself with ribbon fastener technology the tan fitting moves back then the ribbon comes out vice versa Please post success with Processor types!

View 2 Replies View RelatedVery nice machine in every other aspect, except for the noisy fan that I've learned from reading here and elsewhere that HP does not recognize as a problem.
So, I'm thinking of replacing it myself. Can I do that without voiding my warranty? What about having an authorized HP repair center do it for me, if I shell out for the fan myself?
what fan to use? And is there a service manual around?
I have HP pavilion dv 4 1242 tx laptop. I have 320 GB HDD and want to replace with 500 GB HDD. I tried to open the HDD cover from back and I saw HDD in small caddy in which HDD was placed.
I do not know how to procedure further as I am afraid i might damage the inbuilt HDD during removal.
I need procedure on how to remove hdd from caddy with proper tips and precaution to be taken while doing so.
Currently having Fujitsu HDD.Also suggest me which HDD brand to go for?
I need HDD which is quiet and no clicking or any type of noise.
to figure the mess that are DVD laptop model numbers? I assume from the past that the bay in my NX9420 is a 9.5mm multi-bay II, yes?
I was going to grab a UJ-852 drive as it is listed as compatible with the NW9440...and near as I recall the only difference between the two models was the graphics card options and the included warranties.
My NX9420 has been running pretty much 24/7 since I bought in in around in early 2007.
Been through three HDD upgrades and now at 500GB, 4GB RAM...still plugging along wonderfully. Until the DVD drive started popping open just because...I finally had enough, took it out, opened it up and the danged front ribbon cable was so weakened it just fell apart in the middle at the bend...soooo, no real hope of repair so I felt it best to just upgrade the drive to something newer...hence does the UJ-852 and will it fit...I truly have looked, emailed vendors and cannot seem to figure out of the drives are only for the external Multi-bay II or I can remove any attached adapter and use the old mounting bracket then slide it into the bay and be done...maybe a new drive but nothing more...
My sister has a HP laptop with a bad DVD burner, it won't burn and it makes a grinding sound whenever a disk is in the drive. I don't know the model, anyway it's still under warranty and I'm wonder if she will have to send the laptop back in order for them to replace it. Sending it back is a big no no, and I can replace the drive myself.
View 6 Replies View RelatedI have a DV9000, 17inch. A number (that I think is significant) 439112-001 is on the bottom of the laptop.
I need to buy a refurbished/spare part motherboard to replace the one that died in my other computer, but I can't figure out which one to buy. At first I thought it was as simple as buying a used DV9000 laptop or motherboard, but apparently not only does the screen size (13 vs 19 inch) matter, but also a number.
I see numbers on ebay with stuff like "447983-001"--that's why I thought that one number on the bottom of mine was important. But I can't find that number on any motherboard on ebay, and it only turns up 300 pages on google, which leads me to believe it isn't the right number.
I have an opportunity to buy an HP DV5-1157CA in Canada for a great price:
[url]
It's a 15.4" which makes it bigger obviously than the m1330.
Pro's:
-----
Centrino 2/Montevino platform
4 GB vs. 3GB that I have
9600M GT vs. 8400M GS
possible avoidance of future GPU problems
great clearance price of $997 Canadian
Con's:
------
bigger form factor
plastic chassis vs. magnesium alloy and aluminum
lower battery life
no fingerprint reader
still an Nvidia GPU (can we trust Nvidia anymore)
2 Ghz P7350 vs. 2.4 Ghz T8300
If your base enclosure (the bottom chassis cover) gets accidentally damaged, what happens to the service tag when you replace that part yourself?
You see, that part carries the service tag on it for warranty purposes. I know the mobo is also tagged (tattoo'd) with the service tag info, but then what happens if the mobo dies, and you have replaced the bottom cover?
My guess is that you could peel off the service tag from the old part and somehow glue it onto the new one, which wouldn't be very nice.
Also what would HP do if they were carrying out the repair?
I checked out the service manual, to read up on disassembly. Thinking about opening my notebook up and removing the heat pads and replacing them with copper shims to reduce heat. that is, unless someone can find a way to downclock the GPU for cooling purposes... But I'd like to get it cooler so the fan won't have to run all the time.
View 10 Replies View RelatedI recently aquired damage to my laptop screen, an HP dv6000 with a 14.1 inch (wide) screen. I am looking to purchase a new one, however the 'specs' or details of the screen (ex. Video connector info, backlight type) are way out of my realm of understanding.
Before I purchase a new screen, I would like to make sure it is completely compatible with my laptop. How am I able to determine this?
Also, what is the esthetic/quality difference between Glossy and Matte type screens?
I just bought a 2530p, with 1.8-inch 120GB hardisk. The partition is assigned as below.
- 101GB for C:
- 9GB for D: (HP_Recovery )
- 1GB for F: (HP_Tools)
I would like to replace existing 120GB HD with larger one, and would like to ask some question.
1. what is the largest size of 1.8-inch hardisk for 2530p? I refer to "Service and maintenance information" manual, the hardisk size seems only up to 160GB, could I installed 260GB or even larger hardisk?
2. Is it neceessary to keep the partition of HP_Tools or HP_recovery?
(if I delete the partition 'HP_Tools' or 'HP_recvoery', can the OS be booted up?)
Screen on a HP DV6500 cracked and need to replace it.
I have been searching online and found some good instructional sites and videos, and I think I can do this by myself.
Is is safe to buy screens on eBay? eBay saves me about $150 if I but it there...should I go for it or can anyone refer me some where else.
I've got an HDX 16t due to ship next week (if those chinese factory workers aren't slacking off! ) and I plan on replacing the 5400 RPM HD with a 7200 RPM HD.
What's the best way to accomplish this hard drive switch? I figured I'd just install Vista and the required drivers on the new hard drive but I've read that some people clone the existing hard drive onto the new hard drive.
While that sounds easier will it result in a reliable install?
i just found this forum and it seems like you guys could help me answer this question. i have a dv2000 laptop i bought about 2 years ago and the screen has started to mess up. essentially it has two problems.
1. there is always a vertical line about a pixel thick that stays a yellow color. no matter what is on the screen, the line is always yellow. if i bend the display panel a bit it disappears but comes back as soon as i let go.
2. when i open and close the laptop to adjust the screen angle, the screen starts flickering with these white lines. i have to keep messing around with the screen (moving it back and forth) for it to come back to normal. im not sure if a cable is loose or maybe broken.
im assuming that i need to replace the entire display panel but im not sure if i can get away with just buying the lcd screen and replacing it. i can probably get rid of the yellow line on the screen but i think the flickering is caused by something else. could it be a loose cable that i just need to fix?
Broken left hinge is a known problem in HP Pavilion dv9000/dv9100/dv9200/dv9400 notebooks.
HP was fixing this issue at no charge but not anymore. The warranty program has expired on May 31, 2009.
I just finished step-by-step repair instructions.
Check it our here: How to replace broken left hinge in HP Pavilion dv9000
Make sure to use correct hinges. They are different for LCDs with single lamp and LCDs with dual lamp.
Somehow my Synaptics Touchpad on my Compaq V2000 (Model 2402) got zapped today and will not power on at all. This is different than the usual driver problem that makes you think it is turned off. I was tightening up a screw that is close to the pad itself while it was running and the notebook suddenly just turned off. Everything is fine but the touchpad will not power on. It was getting pretty useless regardless. I have been using a regular usb mouse most of the time for almost a year now but still need the touchpad for the obvious. ANyone here replace their pad? I haven't found one used or new yet.

I have some issues with my video since I upgrade the nvidia drivers from the nvidia web site. I removed the drivers and I reinstalled the original ones with the same results.

2. And if so, can I still have the default HP programs on it?Â
3. And if so, how?
