HP/Compaq :: More Dv6500t Power
Mar 4, 2009
Several weeks ago I replaced the power socket on my dv6500t because I had to pull the power cord in a certain directions. (see the thread here: dv6500 Power problem) For a few days it seemed to help although I moving the laptop in a few directions still cased the AC power to cut out.
Now after a bunch of weeks, it's back to where it was before. i.e. I have to pull the cord in basically one of two directions to get AC power. I'm assuming with these symptoms either the power socket on my laptop is screwed up again or there is something wrong with my power cord. Could it be anything else?
At this point, I feel like it's probably the power cord, but I don't want to pony up 150$ only to find out I'm wrong. I could send it into HP for them to fix it. It's a nice machine (core2 2.4ghz, 4 gb ram, etc)

Realizing that my computer is now a little over 2.5 years old, I had a little time to think about whether I should even think about going over to a brand new notebook. Given the specs of new notebooks these days (and a lot of people know here that I spend quite a bit of time at the HP website/FTP), I was wondering what everyone here thinks about me going for a Quad Edition notebook.
In case you're wondering, I use my dv6500t notebook extensively mainly because I am a UCSD Computer Science/Engineering student who does a lot of activities on the computer both casually and for work, for a good portion of the day, everyday. If I get a new notebook, I plan on using it extensively as well.
The specifications for the dv6500t that I currently use is listed in my sig. It additionally has a 12-cell battery which at this moment can only charge up to 58%, and a rather broken left TouchPad button. Warranty is pretty shot at this point, since I had the 1-year standard (which I have no regrets with).
Now, the Quad Edition notebook that I was specifically looking at was the pre-customized HP Pavilion dv6-2190us notebook:...........

I've been following the thread below, but so far have not found the key to recovering from a failed BIOS update on my dv6500t laptop:
CQ45- Insyde BIOS RECOVERY using a USB THUMBDRIVE
I can press Windows-B upon bootup and I hear a single beep followed by the USB floppy spinning up briefly. Note that if I turn on the computer without pressing those keys there is no activity or sound, so I think I'm on the right path towards a BIOS recovery.
The problem is (I believe), I don't know what filename the recovery process is looking for.
I've tried: BIOS.BIN, BIOS.ROM, BIOS.WPF
Also: 30CC.WPH, 30CC.BIN, 30CC.ROM, as well as 30CCF58.WPH.
I've tried this process with a USB flash drive and an SD card, but only the USB floppy drive gives me the feedback that file activity is actually happening (this means that I don't have enough disk space to try 50 copies of the same file with different name combinations).

My HP dv6500t doesn't return from standby and/or randomly crashes when I have my 2x2GB 800MHz OCZ RAM installed. I'm not sure if it's the size (4GB) or speed (800MHz) that is the issue, but it's something, so I need to make a change.
Which of the following RAM configurations would be better/faster? I don't get errors configured with them.
1x2GB 800MHz (single channel)
2x1GB 667Mhz (dual channel)

I got my dv6500t with an 8400GS card to output to my 1080p HDTV but the problem is that the image that displays on the TV is only 90% of the full image as shown on my laptop.
This is via HDMI.
I'd like the images on both laptop and HDTV to match perfectly and I've tried every combination of resolution between the TV and the laptop yet I always get the same result: a fully displayed desktop on my laptop and a cropped desktop on my HDTV.

I'm getting a strange problem on my dv6500t with my dual booted Windows 7 RC install (same issue with the Beta). My searches have been inconclusive.
Using W7 as one user is fine, but if I leave one user logged in and switch user accounts, things start acting wierd...Anti-virus fails to start (I've uninstalled AV and the rest still occur)Can't use the IE button on the task barIE doesn't log in to some websites (e.g. AOL mail)slowness Lots of permanent window and menu artifact ghosting that only clears after logging out This only happens when 2 users are logged in at one time... one user works just dandy.
I'm just suspicious of my HP... the friggen thing crashes on me enough or doesn't resume from hibernate/sleep so I'm not confident in the crap.

I had a friend bring me her HP DV6000 telling me it won't boot.
When the power switch is pressed, all the lights come on for about 4 seconds, then go off. The screen never initializes.
I have noticed that touching the pad near the on switch/speakers will have the same effect.
I popped the switch panel and it looks to be plugged in and all the wiring intact.
I borrowed a known good battery and charger and it makes no difference.
The existing battery and charger work fine in the other DV6000.
Is it possible I need a new switch or cable? or is the mainboard toast?

I have a HP Dv6629us Laptop which has been good for the few years that i have had it and just a few days ago it wouldnt power up.. It tries to power up when i hold the power button for a second then it shuts off which i can hear the harddrive spinning briefly as it does, so i know its trying. I tried taking the Battery out and just having the recharge cable in there and still the same thing powers up for a sec then shuts off when i hold in the power button and the recharge light comes on when i plug in the cable.

I need to open up my hp dv4000 to see if the dc is loose. Before I go taking every screw out of this thing and removing things I may not have to remove, can anyone tell me the quickest way to access this?
Just as a background, the problem is that I need to rig up the power supply cable to that it's pulled taut in a certain way, just to power my computer. If it moves the slightest bit the computer shuts down. My battery won't charge either. My educated guess is that best case scenario, it's a loose connection. Worst case it's the motherboard.

it is old and not worth the time but my 5yr old daughter uses it to for music and school work. so its worth it to her.
zd7260us will not power on. I have bought a new AC Charger & Battery just to eliminate them.
when the laptop is plugged into the charger (w/o battery) the ac light comes on (not the battery charge light!). when the power button is pressed the the power indicator light comes on for 1 second then goes off and the laptop does not boot. I hear no sounds of any kind during this process
when i install the battery and try the above i achieve the same results no matter if the charger is plugged in first or vice versa.
Configurations Attempted - all with no luck
1. tried 1 ram module at a time, different sockets, no modules
2. no hdd
3. no dvd writer
4. no wifi
5. disconnected touchpad
6. cpu removed
i also checked the resistance at the dc jack - all checked ok.
obviously i have taken a apart the lappy and found/seen no obvious visual problems. the DC jack looked to have good connections and was not loose in any way.

The other day I was shutting down my laptop and it paused as normal to install the latest Windows updates. Later that evening I went to power it on and nothing happened. I immediately check the power brick and it's power light was on. Then I swithched to batter and stll nothing would come on. It's as if no power is gettng to the laptop.
I remember a similar thing happened when my hard drive connector failed, so I swapped them out, but changing that had no effect.
what I'm failed to check or what could be wrong before I have to pack it up and send it back to HP?

what HP's ETA is on these batteries? I was hoping to order one before I go off to college, or even sooner if possible. I love my 16t, but the battery life is horrendous even on power saver settings, so any improvement (thus the Boston Power batteries)

I own a HP DV5-1025el laptop with Turion Ultra ZM-80 processor and Windows Vista 32 bit, running at 2.1 Ghz. The laptop is working wonderfully and I have no stability problem at all.
Since I love to optimize my machines at maximum, I started to search some informations about Power States and such similar things, mostly to tweak and reduce battery cpu usage. I made by myself an utility to control CPU Voltage for each pstate, like PumaStateCtrl, but more flexible. It's in an early stage, but it seems to work good for ZM processors,
I studied the official AMD datasheets about Turion and Turion Ultra (mainly ZM and RM series) processors and found that they have 3 active PStates (actually they have 8 pstates, 3 are activated and 5 are not). My ZM-80 has these pstates:
PState 0 - 2100 Mhz, 1.100 volt - Enabled
PState 1 - 1050 Mhz, 0.950 volt - Enabled
PState 2 - 525 Mhz, 0.800 volt -Enabled
Then there are other pstates from 3 to 7, but are disabled:
PState 3 - 1050 Mhz, 0.950 volt - Disabled
PState 4 - 800 Mhz, 1.550 volt - Disabled
PState 5 - 800 Mhz, 1.550 volt - Disabled
PState 6 - 1050 Mhz, 1.200 volt -Disabled
PState 7 - 1050 Mhz, 1.200 volt - Disabled...........

HP dv2500t with nVidia overheating problem about 2 years ago. About 3 months after my 2-year extended warranty expired, my laptop started having problems with the screen that split into 8 parts and showed lines running across. Unfortunately, HP was of no help since my laptop wasn't on the list of those recalled and asked me to pay an extra $400 to get it repaired.
After doing research on the net, including this site, about this problem, I decided to replace the motherboard myself. I ordered an exactly the same motherboard that came with the same nVidia chip from a reputable seller who specialized in selling used motherboards. He assured me that it was tested and even recommended adding a piece of copper on top of nVidia chip. So I carefully took apart the laptop, added a piece of copper that came with the new MB using instructions posted on this forum (with Arctic silver 5) and reassembled it.
To my surprise, the laptop wouldn't power up. When I plugged the charger, the blue LED light would go on both the front side and the right side where the charger goes. And then there were no other signs of life from the laptop. I thought maybe I didn't connect some wires properly. So I disassembled and reassembled the laptop 2 more times. All to no avail.

I'm planning on purchasing an Elitebook (8740 maybee) that I want to semi-permanntly dock to a monitor and external keyboard. But I dont like the idea of having to open the lid, power on the laptop, close the lid and then use my system, so I was hoping there is a docking solution out there that would have a power button mounted so i could power the laptop on and off with the lid closed.

I've been thinking about buying a new power adapter to replace el-giganto that came with it. I understand that there is at least one Kensington power adapter that works (model 33197). That one, IMO is a bit too large. Curiously, that adapter is not directly visible on Kensington's website for Laptop Power Adapters, but is searchable (by part number).
So my question is whether there are any people out there that have used, for example, the model 38066 or the model 38067 successfully? Those two models are smaller (physically) than the 33197, but they don't actually list the Wattage they provide (they're listed by Voltage and Amperage - which kind of makes Wattage, but not exactly). It seems as though they might be 90W adapters (as the product pages make continual reference to their power efficiency over "other 90W adapters" which leads me to believe that they're probably around 90W adapters.
Or whether the model 38031 or 38030 will fit? These adapters are a bit larger, but appear to offer more input amperage. Though they also say "Up to 90W output" so ...
From what I understand, the HP Envy 15 will throttle the machine with less than 120W of input wattage.
Also, the 33197 is apparently an "old model".

been using the IBM power manager. After changed to the hp dv7, I wonder is there any power manager that work like the IBM's?
Basically, I need a power manger that I can use t set thresholds for charging.
Whenever the power level drops to a certain percentage, the AC will start to charge the battery till the stop charging pecentage is reached..
Is there any, or can I use the IBM power manger on the hp laptop?

It seems that the the end of the power plug (the center pin) is broken.
I have a HP 8710p, and this AC adapter ---> [url]
What I'm asking for is a picture, or a rough explanation of how LONG is the gold'ish connector (the center pin) inside that plug.
I'm asking because I want to find out whether it's the motherboard power connector that's broken or if the center pin inside the DC power plug somehow broke and doesn't provide the power..

I remember reading somewhere about someone recommending to do some kind of mod that will drop the voltage for the nvidia 9600 gpu without any performance sacrifice and gaining better battery life.
Yes I know this laptop isn't built for battery life and I barely use it off the adapter but I'd like to reduce the heat thus extending the life of this ticking bomb
