HP/Compaq :: 8710p- Power Plug

Oct 12, 2009

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..

Dell :: 9300 No Boot After Power Plug Swap

May 14, 2009

It is now charging and all but when I try and boot all that happens is the the Caps Lock, Num Lock, and Scroll Lock lights turn on for about a second or 2 then they turn off. Also the "charging" light extinguishes when the others light. I get no beeps, fans or anything.

Now my buddy, said that he did a similar replacement on his daughters laptop and that "the board needed reprogrammed afterwords"?? I'm not sure what he means by this .....

HP/Compaq :: HP Nx7400 - Whenever I Plug The AC Adapter To My Laptop Whole Performance Is Very Slow

Apr 1, 2009

I have an HP Compaq nx7400. I've had it for over 3 years now. I've never changed its battery ever since I bought it.

Specs: [url]

Over the past few weeks, I've been having an unusual problem. Whenever I plug the AC adapter to my laptop, the whole laptop performance - from the second I switch it on - is very slow. The moment I pull the AC adapter from the laptop, it instantly operates at a normal and fast speed again!

I figured that it must have been a problem with the AC adapter (it's had its fair share of use - being swung around and dragged to lectures...). So I ordered another one off Ebay. Today, I got the new adapter and when I plugged it in, the laptop only went on AC power. It worked fine - fast as normal. However, it was not charging - just on AC power. I am starting to question if the adapter was really as "genuine" like it was advertised on eBay. But anyway... after about 4 hours with the new adapter on AC power, it stopped recognizing the battery altogether and alerted me with a Critical Battery sign. Of course, a few minutes later, it went dead on me - the laptop switched off. It was as if I removed the AC adapter myself, only I hadn't. Now, I am trying to plug it in again (the new one), to see if it will be able to power up again and it just won't respond at all.

On the other hand, when I put the old AC adapter, the laptop switches on but doesn't charge. Again, it is extremely slow with the adapter on, and fast when I pull the wire out. Only for a minute or so until it dies on me again...

Apple :: 13" Only Has 1 Headphone Plug

Jun 10, 2009

i was looking at the pictures and i saw that insted of a headphone and a mic plug it only has 1, does that mean it works as both and the apple 3g headset will work perfectly for it?

Also I never had a mac b4 but the 13" macbook pro is really tempting, I always heard stuff about macs like their bad for gaming, works bad with adobe flash, and not alot of software out there for it. Any of that true?

Dell :: To Repeatedly Plug Laptop In Before Battery Is Low

Dec 24, 2008

Just got my first laptop, and my wife likes using it on battery in her favorite chair whereas I prefer to sit it on the coffee table plugged into the outlet. So we end up charging it up when I use it, and only draining it to between 90 and 50% or so when she uses it. Is this okay to do, should I fully drain it once a month or so, am I being too paranoid about taking care of it?

Apple :: Safari Flash Plug-In Is Killing My Battery

May 14, 2010

When I'm watching flash video in Safari my battery life drops to 2-3 hours ... When I'm watching the same content in Firefox I'm good for another 5-6.

What is going on here and would Chrome resolve these issues? Yes I know I could try out Chrome for myself but I alone am not a good enough sample size for the question I'm asking.

At any rate, why does Firefox handle flash much better than Safari on OS X?

Dell :: ESata Plug Differences: E6500 Vs. E6400 Vs. E4300

Mar 5, 2010

I wanted to share with the forum some strange, yet interesting findings that I've come up with in the last week or so.

First, some background. I am the IT manager/senior admin for my company. I do all of the purchasing and high end tech stuff, so I get to play with a fair amount of hardware and equipment before deploying it to the company.

For the last year or so, I've owned an E4300 as my work laptop, and have been purchasing E6400's to deploy to our company. Some of our consultants have dual internal hard drives using the Newmodeus optical bay caddy, and use an esata/usb combo port to power their optical devices when they need. We also utilize the Coolmax esata/usb enclosures for external drives. All of these devices work great on our older E6400's and my E4300.

Recently, I made another order of some E6400's and 2 E6500's as a trial. No matter what I do, the Newmodeus cables (I have a hard drive one as well) will NOT work with the E6500 and 1 of our new E6400s. Occasionally, by wiggling the cable in the plug and pushing hard, I can get a device to be detected for a few seconds. I decided to have Dell come out and replace the motherboard in 1 to see if I got a defective board.

Well, that didn't help at all, so I dug a little deeper. I borrowed a colleagues Coolmax enclosure, and plugged that in. To my amazement, it worked fine. I compared the esata cables....and the Coolmax cable is ~1-2mm longer than the Newmodeus cables.

The port depth on some of these machines must be a little deeper than others, not allowing the cable to fully seat and get a good connection. I have 2 E6500's and 1 E6400 with this issue.

My next plan of attack is to use a small saw to cut a little of the plastic off the Newmodeus cables to see if I can get them to seat a little deeper. I will report back my findings. I never thought something so simple would be such a PITA.

Apple :: MacPro Usb Slots -NO Space For "plug Ins"

Jan 13, 2009

i bought a AT&T wireless usb plug that fits perfectly and works great...Then i bought the highly rated logitech vx nano wireless mouse which comes with a tiny usb plug which could be left in the usb slot...So whats the problem?? both devices cant fit at the same time [/i][/b]on the laptop becuase there is not enough space for the both usb plugs to be occupied. Is there a solution to this?? Are there any adapters that I can use which will allow either one (Preferably the ATT wireless) to be plugged into another slot on the Macpro?

HP/Compaq :: DV6000 Won't Power On

May 4, 2009

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?

HP/Compaq :: HP Dv6629us- Power

Feb 24, 2010

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.

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)

HP/Compaq :: How Do I Access The Dc Power

Jan 18, 2009

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.

HP/Compaq :: HP Zd7260us Will Not Power Up

Dec 28, 2009

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.

HP/Compaq :: Laptop Will Not Power On

May 2, 2010

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?

HP/Compaq :: Boston Power Batteries

Jan 13, 2009

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)

HP/Compaq :: Power Handling Ondv5

Apr 19, 2009

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/Compaq :: HP Dv2500t Wouldn't Power Up

Dec 13, 2009

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.

HP/Compaq :: Is There A Dock That Will Power Up And Down The Laptop

Apr 15, 2010

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.

HP/Compaq :: HP Envy 15 (v2) Power Adapter

May 18, 2010

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".
