HP/Compaq :: NW9440 Battery Rebuild

Feb 20, 2010

The original battery pack on my NW9440 is getting very tired.

Before I rush out to buy a new battery pack, is this one that can readily be opened up and the Li-Ion cells replaced? The form factor suggests it has 8 AA sized cells inside - if only I can open it without destroying it, replacing the cells should be a doddle - catch is I can't work out the non-destructive way to open this.

Dell :: Anyone Rebuild The Battery In Vostro 1500 Yet? / Questions

Feb 5, 2010

My battery in my Vostro 1500 lasts 8min running full power now so it is mostly dead. I have been unemployed for 11 months now so funds to buy a new battery are very low.

I have soldering skills and I upgraded the CPU in this thing so this should not be a problem. I just have a few questions...

Does anyone have any tricks on cracking the weld on the case? Besides scrapping away at it with a knife for 3 hours.

How much would the replacement cells be (estimate)? Has anyone done one of these batteries know what is going to be inside of mine?

Dell :: HD ReBuild

Jan 10, 2009

i have an XPS 1210 with Nvidia card. i intend to bump it up to 4mg memory. it is a great laptop. Dell recently replaced under warranty the LCD screen.

i have managed to mess-up the operating system and need to rebuild the machine as the restore is corrupted. two questions -

1. is there a sticky somewhere on this forum to step me through the re-build?

2. i took title of this machine from my former employer. i have the XP disk but not the Office disk. can i get the Office disk from Dell for a small fee? i am still under warranty and have next business day support.

i can probably get the Office disk from former employer but would rather not deal with it.

Acer V3-771 :: Cannot Get Into BIOS To Rebuild From Recovery DVD

Jan 31, 2015

My Windows 8 install got corrupted and will not boot. So I just want to get the laptop to boot onto the recovery DVD or any DVD so I can rebuild it.
No matter how hard I press F2 nothing happens and I keep getting "No Bootable Device, Hit any key." This just takes me into an empty boot menu! I have tried with what I know to be bootable CD/DVD in the internal and have used external DVD drives.
I just want to get into the setup to boot onto the DVD drive.

HP/Compaq :: DV7 Battery Care

Apr 16, 2010

It's been since the DV6000t that I looked at battery & notebook technology.

From then I believed to cyccle the battery a couple times and store it out of the machine @ around 60%.

Is it still so? Will just plain leaving it in the machine all the time plugged in shorten the life or effciency? Or have things progressed?

HP/Compaq :: HP Omnibook 510 Battery

Oct 25, 2009

The 6-cell lithium ion battery would only run it for about 10 minutes. I tried replacing all the lithium ion cells with new ones, made for cell phones, so I doubled them up.

Then, I just got blinking lights when pressing the battery circuit board 'test' button.

So I left it for a long time, several weeks.

Just picked up a complete battery conditioner, with a built-in balancer, normally about 100 bucks for 25.

So I disassembled it, but then probably waited too long (fell asleep) before rehooking up the old cells.

Figured out now I should have left everything alone from the beginning, done several drain and recharge cycles to recondition the cells, and would have had the pack like new.

Now I can charge the pack with the bench battery charger/conditioner/balancer, but the electronics seem 'dead' on the circuit board strip. The laptop thinks it's on AC power when it's on battery, and shows no sign of powering up the pack.

I'm thinking leaving the replacement cells out for too long, before I put the old cells charged, back in, made the circuit board 'forget'.

HP/Compaq :: Envy 15 Battery

May 20, 2010

i've had my Envy 15 for over two months now and although i don't use it frequently enough my wife noticed that on a full charge, unplug then the next day or so the battery is drained.

Basically here is what she does:
she would charge the laptop up
unplug then use it for like 20 mins
shut down Start>>shutdown
CLose lid

About or two days later she would try to use it and the thing wont turn on. Plug in the brick and voila! thing comes up.

Is she not shutting down properly? or is there some program on sleep eating the battery?
Or is that the rate this battery drains?

this is still on the FACTORY image, i didnt rebuild it

HP/Compaq :: HP 6720 Battery

Jan 9, 2010

I've a 2 year old 6720. The problem is that it is giving me a battery time of around 1 hour max ( a couple of min more maybe) while doing browsing, word, basic stuff.

I installed the HP battery checker software and it says that the health is good, dunno how accurate the app is but thats what it said.

A bit of history, I've been using the notebook 90% of the the time plugged in, and powered on about 15-24 hours a day.

So, time to change the battery? or anything can be done to improve the times?

HP/Compaq :: Dv6 Battery Wear Off

Oct 6, 2009

I got my hp dv6 last Monday, so it's quite new. About three days ago I downloaded System Information for Windows trying to find out which was my GPU temp(what I didn't find, it only shows only HDD and CPU temp) and looking other stuff I noticed that my battery wear off was 7% while the battery is(was?) also new, so it got me preoccupied, so I checked it again yesterday and it was 9%!, I checked today and it's at 10% . Just c'mon I don't dedicate all my free time to plug and unplug the battery ,so why the fcuk(note there's no grammatical error) it wears off so quickly,

HP/Compaq :: Calibrating The Battery

Nov 24, 2009

I have been trying to calibrate my HP (DV2700) battery. It would drop from 40% down to 6% and put the computer into standby mode. If I were to turn it back on, it would drain down to 0% and run for another 30 minutes before it powers off.

After that I would give the battery a full charge. I have tried to charge it while the computer was in sleep mode, and while it was on.

It doesn't help that RMclock reports the remaining capacity as like 21mWh remaining when its at the "0%" mark. I do switch between 3 batteries so not sure if that does anything negatively.

(Yes I am well aware that draining it is bad and calibration is not always necessary)

HP/Compaq :: HP Needs To Design A New Battery For The Envy 15

Jan 30, 2010

Now I haven't used my notebook on battery very often but judging by reviews and battery use here and there I do believe HP could've done better with designing their battery. I mean they can achieve up to 24 hrs with an elitebook (given its like a battery slice plus sticks out in the back) but don't even get close to a proper battery usage time with the standard battery. I've read reviews where the battery runs about 2hrs on battery and even some around just an hour, and that really is sad. I know the MacBook Pro was able to get about 7-8 hours out of a thin-n-light(given crappy hardware) so I know hp has the resources and capability to make this new battery. At least bring it out by the time the next gen Envys will come out and make sure these batteries will be backwards compatible with older Envys as well. Besides the battery life and locked multiplier I love my Envy

HP/Compaq :: Can I Use My Laptop While Doing A Battery Calibration

HP/Compaq :: Dv5t Battery Won't Charge

Jan 18, 2010

My dv5t won't take a charge. The charge indicator light does not come on and the battery charge indicator graphic in windows doesn't show it is charging (plus the AC adapter isn't getting warm). My laptop is now out of charge and I have no way to use it. I think the connector at the PC end might be loose or something, but perhaps it is just the AC charge adapter.

The reason I say the conenctor at the laptop end might be loose it because I can wiggle the charging plug around in the socket quite a bit when it is plugged into the laptop power socket (the round socket at the rear of the right side). Sometimes the charge plug has weight on it when in my lap since the darn things sticks out so much, and I am wondering if I have caused the socket to malfunction internally (loose lead or something?).

HP/Compaq :: Dv5t Battery Stuck At 0%

Apr 6, 2010

My battery will not charge even though I just got it about 2-3 months ago from HP while my laptop was still under warranty. When I hover over the battery status it tells me 0% available (plugged in, charging) but no matter what I do it won't charge. I've tried charging this battery on my other dv5t with a different AC adapter, but the same thing is happening. Are there any tricks or anything that I can do? This is a new battery and for it to die after 2-3 months just doesn't make sense. HP battery check tells me the battery health is Good.

HP/Compaq :: Battery Full: Charging Cut Off

Aug 30, 2009

I just recently bought a 12-Cell battery for my DV2730.

My original 6-Cell battery fails to charge anymore so my laptop would not power up just on battery power.

I'd like to know more on how to take better care for my new battery, and so my question is; does HP laptop, cuts off charging when battery is already full? Because i noticed that the "charge/lightning LED" does not stay ON anymore when battery is full. Is this a correct indicator? Or should i remove my battery when running on external power?
