20 Most Recent HP Pavilion dv4000 Notebook Questions & Answers

That particular series of HP computers has a recall with an extended warranty for just this problem. Call HP, they will have you go through all the first line cures but tell them you know of the extended warranty for lost wireless problems. They'll replace the mother board. Make sure you back up all your data when you send it in. I've sent them nearly a dozen and some they reformatted the hard drives.

There you are.

1) connect to external monitor to see if it works. If it doesn't work, then its a video card on the motherboard issue. 2) If connect to external monitor works, then its the screen or screen connection on the laptop.

its no wireless its bluetooth i guess,, correct me if im wrong

first off there is no such thing as a DV4, sorry!!!! dv4-1000, 1280,1300, right?,. it's 10 old, the battery is that old is no good, the dash matters too if present (details do) or is it a DV4000, 13 years old not 10 .??? why not post the full model and p/n off your PC service tag so i can show you matching manuals to read and follow, ok? THE AGE MATTERS AS DOES REAL MODEL NUMBERS!!! that is blink code, try to learn how to read them , counts them. here is a list of tests, simple. to harder. 1; Remove that old big battery 10 years old , it shorted. 2: run on AC power only. in fact can do this forever....... 3: next is the fan working? fan is next and now, does it? 4: flash codes, count them and report them, easy no? 5: the coin cell is next , it is 10 years old that too is END OF LIFE why not replace it too ,now even if good, to avoid problems later, ? My answers are for DV4000 only not the DV4-1000 and up vast series of laptops. vast versions of them... the coin cell , HP name RTC battery, all die at 5-7 years old. yours is well beyond that. ok? lets do chapter 5 covering just that now. here it is, pg 5-20 pdf page 126 we take it it out if lower than 2.9v (a dmm meter is cheap) we replace it, 3.3 is normal when the fall to 2.9 (think cliff) they fail fast and the BIOS GOES NUTS, in fact the PC can be totally dead. see the manual , if wrong next time tell full service tag data.!!! https://www.manualslib.com/download/71706/Hp-Pavilion-Dv4200.html that caps lock flashing are codes, learn to count them my wild guess is it is the code for BIOS NVRAM corruption. the cure is posted here over 1000 times. and a million times at HP.com real, we are not HP.

Usually this means u have a damaged led panel or panel ribbon connector try a new LED screen first try ordering from Amazon get the numbers off the back of the screen

got nothing?, (means PC is dead or just key buttons dead) tell what works and not, we can not watch you or it. please Series: DV4000 is a series of LT. it has a full & real model stated on its service tag, only THAT works, so how'd it get w8? there? (bought FROM MS or HP?????) why mess with BIOS> ? if this fails it bricks the PC. (if you must flash always flash using the usb stick way. (freedos) not only that using the wrong model to flash, HP sold this series with AMD and Intel processors. oops...... next time before doing such big thing ask, hp first? both model and p/n matter, when doing updates or buying parts. big time! learn that HP page, the exact model and OS must be selected or it shows you the WRONG BIOS and wrong driver and wrong HP APPS. for a fact. here is the series page, dangerous, imo https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-dv4-4000-entertainment-notebook-pc-series/5082208 use the real page by using real models # BIOS101 pick any LT. even yours. the PC can have 6 different network chips used in the long production run.. and GPU and other features, very different. in your case even the CPU vastly different. amd/intel so giving that fact, picking the right BIOS binary can be very hard. best of all why not ask HP before even walking the path. https://h30434.www3.hp.com/

you can make a dual book (multi OS) on your laptop so that you can just switch over to XP or vista and vice versa.

try this article on MS on how to install a multi OS. i haven't tested it in vista though...but i think it would work..please let me know.

also..you can use a Virtual PC and install XP there, its much more easier.

If this is a windows computer, you can look online for a program to erase your current windows password. I found one called Offline Windows Password & Registry Editor. I had to 1. download the program onto a second computer that I could logon to, 2. Burn the program to a DVD or USB stick 3. Go back to the computer I forgot my password on, and turn it off/on 4. As it is turning on, press the F?? key that the screen says to go to the boot menu. 5. Tell your computer to boot to the DVD or USB stick 6. Follow the instructions included with the software to reset your password to blank. Note: Remember what account you login with, so you reset only that account's password. 7. You should be able to reboot your computer, and login without a password.

you may need to replace the keypad or try cleaning under the keys.

Generally laptop speakers aren't that loud, plug in an external speaker into the headphone jack for higher volume. Bottom right of the screen should have a speaker icon to change the volume.

You may have temporarily turned it off by accident. See the image below, if not reply and I can suggest other things.

While online, Right click on my computer then go to device mangers click go to audio devices right click then go to update device driver or update driver

First, why are you downgrading? Unless you have a particular piece of software that you HAVE to have that doesn't work on Vista, you shouldn't downgrade. Windows XP is outdated, and very soon won't be supported by Microsoft. So unless you have some overwhelming need to have outdated software stick with Vista.

Having said that... If you still want to go ahead with a downgrade to XP, first you'll need a copy of Windows XP and a serial number for XP.

(Note, everything on your computer WILL be erased so make sure you do your backups before you continue!!!)

1) Put the Windows XP CD in your computer and restart it. If your computer is set up to boot from CD, it should start automatically.
2) "To setup windows XP now press enter"
3) Agree to the licensing agreement
4) Choose whichever drive you want to install Windows on and press enter
5) Choose "Format the partition (Quick) and press enter
6) Press "f" to format the drive
7) It'll do the install then after a reboot it should show Regional Option, click next
8) Put your name in and click "Next"
9) Enter your 25 digit product key (Windows XP Key) and click next
10) Enter whatever you want for your computer name. It could be "Desktop" or "Laptop" or "Family System" whatever you like. If you're installing XP Professional, you'll also see a spot to type in a password to get into windows. You can leave it blank if you're the only one using it, or password protect it so no one can get in. (Then Press Next)
11) Make sure your Date/Time and Timezone is correct then press Next
12) "Typical Settings" next.
13) (IF XP PRO) Choose "No" then type in WORKGROUP
14) It should start windows after you've done those steps and you can register with Microsoft and create additional users at this point (All self-explainitory).

You might want to print this out if you're going to go ahead with the install.

If you want to reset the BIOS password remove the computers battery and then open the backpanel and remove the bios battery for about 20sec. If you want to reset Windows admin password this is harder issue -> easy way make a backup and reinstall windows and then restore the backup.

Either the computer came with a recovery disc, or during the boot up at the HP screen thre should be some options. Typically F11 will get you into a recovery partition which should allow you to re-install Windows. This will wipe out any data you have.

It could be your wireless card which you can replace through the bottom of the machine. Take it out and get the part number and do a search on amazon for it. It should be fairly inexpensive $5-10 I'm guessing. If that doesn't work I would just get a USB wireless adapter which you can also get from amazon. Good Luck!
