Top 20 HP Pavilion dv4000 Notebook Questions & Answers


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.!!!

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.

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.

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.

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!

If the restore partition is still there, press either F8 of F11 just before boot up and follow restore/rescue links from menu.

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.
