HP/Compaq :: C500- Power- Wont Charge And It Wont Run Without The Battery
Feb 22, 2009
i have a compaq presario c500 i have a problem that it wont charge and it wont run without the battery ...i know its not the charger and not the battery at fault as i have two of the same laptops and tried both parts from the other laptop with no sucess . is it more likely to be the motherboard or the actual mains plug on the laptop ....when i plug the adapter into the laptop it shows a charge light on front and the battery icon on screen shows as charging but it still dies the only way to get round it is it to charge it in my girlfriends laptop then put the battery back in mine ...is there any setting in the bios that would change how its charged

i have a compaq c500 (c501tu) laptop.
for about 6 months now when i run the laptop on battery power it dies after 15 mins.
i thought i needed a new battery but tested my existing one on my friends laptop which is the same as mine, a c500 series.
after fully charging the battery on my laptop i removed it and plugging it into my friends laptop and it gave me 45 minutes of power compared to 15 minutes on mine!
i did this thrice and had the same results. but when i plug it back onto my laptop i get only 15 minutes of usage.

i am attempting to replace the CMOS battery in my presario; however, i can't seem to find it. i have tried to search for the service manual for this model but could not find it. i looked at the service manual for the C300 series and it indicated that the CMOS was under the memory module, but it isnt in the same place in mine.

The computer is in dead state the next morning after I switched its Windows power plan to high performance. In order to unlock power plan options, I disabled connected standby via a registry key in HKLMSystemControlSet001ControlPowerCsEnabled to 0.
After investigating, I read that this computer doesn't support normal hibernate wake-up process other than connected standby. I select shut down option in the menu (hibernate option disappeared). It's possible that shut down option in the menu was actually set to sleep/hibernate in power settings by default.
The battery was at 100% before I last turned it off.
The LED power indicator doesn't light on when power supply is connected on either DC or microUsb.

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?).

I just bought a HP netbook for my sister for christmas and we got it all set up today fine. Only problem is that the battery (it's the extended battery - not sure how many cells) just will not charge. It has been plugged in all day so far today and it still reads as 0%, and when you unplug it, the computer will just die (because no battery power).
Granted the unit WAS an "open box" when I bought it so perhaps this is the reason it was originally returned, even though the unit looked brand new. What can I do to resolve this problem other?

I have replaced the battery. A computer repairperson has had me run the battery down and then charge it completely before I turn the computer on again. That would work sometimes. It would sometimes recharge if I unplugged it, shut off the computer, took the battery out, then replaced the battery and plugged it into the power cord. The computer had sometimes run on the power cord other times it would continue to run on the battery when it was plugged into the power cord. The computer battery has run down, even though plugged into the power cord. It will not recognize the power cord and charge. I have put the old battery into the computer and turned it on, so I know the computer will work with power. It does not charge the old battery either. I left the battery out for about 12 hours, replaced it, plugged it in and it still doesn't charge. There is not enough power in the battery to turn the computer on at this time. I would like to be able to charge it long enough to be able to get any files off the computer that haven't been backed up.

it's a dv9000.. 17" so i don't lug it around that much... it's usually plugged in so i don't drain the battery or anything often at all.. but i noticed earlier this week.. that when i did happen to use it while unplugged, when i plug it back in the taskbar icon shows that it is not charging back up again! right now it's at 44% and for the past few days has not changed at all.. i've restarted, etc.. is this a problem with my battery? a problem w/vista? something i can manually configure/fix?

I recently was given an HP dv2125nr laptop that needed a new motherboard. I purchased a new one and replaced it and the laptop was up and running. I was happy and figured that I had just salvaged a decent laptop.
When I first turned it on I noticed it wouldn't run off battery power but thought, no big deal it just needs charged. That turned out to not be the case. I went about reinstalling the operating system using the recovery partition and didn't give much thought to running it on battery til I noticed that the power icon said "On AC Power, Charging" It didn't give me a percentage however, and when I double clicked to inpect further I noticed that the battery icon under battery #1 had an X through it, and it also said "Total Battery Power remaining: Unknown".
At this point I updated the BIOS because I had seen a few forum topics that suggested this, I also made sure I had the most up to date drivers off HP's site for all hardware. Another step I took was to uninstall the "Microsoft ACPI-Compliant Control Method Battery" then scan for hardware changes and let Windows reinstall it. None of this worked.
I then assumed I had a bad battery on my hands, I ordered another one (not an HP, a cheaper one) and when it came I plugged it in overnight to charge and after about 12 hours turned the laptop back on to see if I had a fully charged battery, I did not!
It was acting in exactly the same way the original battery had acted. The only difference that I could notice was, that on one of my many reboots the icon under battery #1 in the Power Meter window only had a single red slash through it, instead of a red X.
Things I have tried:
1. Updated BIOS
2. Updated all drivers
3. Fresh install of Windows XP (again after the original recovery install)
4. Unistalling the "ACPI-Compliant Control Method Battery" in Device Manager.
5. Ran HP Battery Check Utility, has a divide by zero exception upon startup, then says no battery is present.
6. Booting directly to BIOS and allowing it a chance to charge overnight.
7. Swapping both batteries (no difference).
8. Taking back apart casing to make sure there were no loose wires.
My only thought next would be that either both batteries are bad (seems unlikely) or that there is a problem with the new motherboard. The motherboard being bad would surprise me, as it is able to run just fine without using battery power.

I've read that the best way to prolong the life of a notebook battery is to take out the battery and store it at 40% charge. However, I like to keep my battery plugged-in as a backup power source. Is there anyway to make my laptop stop charging the battery at around 40%? That way I can extend the life of my battery while still having protection against a power outage.
System specs:
HP DV7T-2000
Core 2 Duo P7450
4Gb RAM
ATI Radeon 4650
320Gb HD

Got a new HP battery for my laptop and it failed the battery test from the HP Advisory program. It telling me one of the cell is not working and that I should replace it.
Did I get a defective battery or I didn't charge it properly?

My Presario V6310US battery wont charge to 100%, Windows usualy reports that it's at about 41% but never higher.
Does this usualy indicate a battery on its way out? The laptop isn't extremely old so it seems odd. My Gateway is older and has no problems.

I have a Compaq Presario V5000 that will not power up. Fans and drives don't spin up. The odd thing is it will charge the battery when hooked up to the power supply. The orange lightning bolt is solid until it is fully charged then it blinks. I have a second power supply and I get the same result.
The laptop does nothing when I remove the battery and try to run in directly on the power supply. I have re-seated the memory, hard drive, DVD drive, WiFi, keyboard, touchpad, monitor, audio board and replaced the power button board.
I also checked the power level going all the way to the processor and all is well.

My ancient C500 fan is noisy, a constant slight grindy noise. Its been like this for months and I cant take it anymore. Can I clean or replace it w/o too much trouble or is it time for a new laptop? Looks like I'd have to take off the whole bottom to get at it...which Iwill do, if it will shut the damn thing up.

i just recently posted a disscussion on this model and i recently took it to a repair shop, at first they wanted $180 to fix it, which was ok, then they told us it needed a new harddrive, so it would another $100 more, so we went and got it from them without any work being done... now i have no idea what to do i just spent $200 to buy the thing and now its broke.
Symptoms:
Turns on to the windows recovery failure screen, push enter to continue to start windows and it trys to start up, it goes to the windows screen attemps to load for a second, then flashes a blue and shuts off and repeats the process.

I've got an old C501NR with 80 GB HD that blue screened and died. Disk check indicated failed sectors. Wont boot into windows. Hp said its dead or dying. So I bought a 160 GB and Windows wont see any of it, neither does Bios. HP said it was too big, would only handle 120 GB so I ordered one of those, same speed/cache as the original. Same issue, its not found by Bios or Windows setup disc.
Here is the fun part: HP now says I can only use a certain part number which seems like total BS to me. Surethe 2 I tried were western digital and they come with Seagates, but so what? So if it isnt THAT that prevents me the puter from seeing the new drives, and that seems highly unlikely, what is it?? The drives are seating and connecting just fine.

i have a presario c552us laptop and it recently started making weird noises around the fan underneath. i took a look and it seems to be coming from the fan. it sounds like some1 stuck something in there and its hitting the fan blades. doesn't happen all the time either. when the fan is spinning, sometimes its great(like right now) and other times it sounds horrible.
i took apart the whole laptop and cleaned out all the dust, especially in the heatsinks and fan assembly. it seems to spin fine when i use canned air on the fan blades. it has the normal high pitch fan spin without the grinding noise and what not.
not sure what the deal with that is, but maybe the fan has issues gripping or spinning itself.
so it sounds like i pretty much need to replace the fan and the motor.
can i replace just the motor and fan? or do i have to buy the whole assembly with the weird shaped heatsink?

I accidentally dropped my Compaq Presario C571NR and it fires up Ok, but the screen is black. I have tested the video card with other monitor and it seems to work fine. I did some research and I found that it could be that either the inverter board or the backlight might have gotten damaged. I have purched a new inverter card online (awaiting arrival) to replace the existing one, but I wanted to know if any of you know which of them has the propensity to get damaged first, the inverter or the backlight?
I'm hoping is the inverter because it seems the easiest to replace, but if it's the backlight, then I'm screwed because I've read it's quite difficult to replace and it's more expensive. Compaq says they'll charge me $300 to fix it (since my warranty has already expired) but I might as well get a new one if the new inverter doesn't fix the problem.

I recently reinstalled windows XP though I dont know if that has anything to di with this, I didnt notice the problem till a few days later so I tend to think not. BUt now there is only a slight difference in screen brightness when I plug in as compared to on battery. I wonder if my backlight is failing.

I'm thinking about picking up a usb wireless n adapter; which means I won't be needing the internal wireless nic. Since that's a mini PCIe slot, I was wondering if anyone has tried replacing that with one of the many SSDs floating around the web...
2 main questions I have about those:
If they're mini-pciE, why are there sata versions and pata versions out there? There's no sata or pata connector on these cards it seems, the pci-e connector is all there is. Do they somehow use the sata/pata controller on the motherboard via the pci-e bus?
2nd question; would there be any way to boot from one of these? The bios has a bunch of options for booting up, network, usb, usb floppy, etc... but none for mini pci-e or anything like that...
Laptop is a presario C500, more precisely c551nr, broadcom 802.11b/g nic, 80gb toshiba 5400rpm slow ..... hard drive, and a celery 440 running the show..

My HP 250 laptop is barely 6 months, a few hours ago I shut it down, and just when I tried to power it again it won't come on,the little light close to the charging port that indicates if the laptop is charging won't even blink, I've tried several stuffs like: removing the battery, and connecting the charger directly,I also removed the ram and put it back. Now my laptop isn't charging, with or without the battery, and it won't power on. Its just completely dead, what could be the problem.

I have a old hp zv5000 and it seems to randomly shut down, the problem is very peculiar. The battery on the hp cant hold charge for more than 10 minutes but the problem lies in the charger/laptop itself. The charger only seems to be able to charge the battery and the system only seems to runs on battery power, the battery runs out and the system shuts down (without any notice). When the battery is taken out of the system, it fails to start up.
i am guessing somewhere in the mobo :S since the laptop itself cant turn on external power when the battery is disconnected and only seem to run off battery power.

I have a HP Compaq 2230S business laptop, but this question could be put to any HP laptop. The fan is constantly running when the laptop is plugged into the power outlet, but as soon as I pull the plug to run on battery power the fan powers down and stops. I re-plug the laptop back in and the fan kicks up again.
This is not good as I almost burned myself when I picked up the laptop after an hour sitting on the table on battery power. The hard drive is right beside the processor, so the laptop gets really hot.
Vista x64 Ultimate is what I'm using at the moment and my power scheme calls for 1% minimum and 100% maximum CPU on battery power.

When my laptop is plugged into AC power, and I decide to move to another room and unplug it, the laptop suddenly freezes. All the programs do not respond and the only way to fix it is to reboot.
HP tech is trying to help my by telling me to test the battery life and resetting the bios, however this laptop is only 2 months old and I had the problem since the begining.
Its a dv3 Pavilion.

I have a Dv6500 series notebook with C2D 1.5 GHZ processor and Nvdia 8400gs Graphics card.
My notebook came with vista preinstalled which i did'nt like...
so I Installed XP primarily using the guide at this location
www.nogodforme.com
and
Installing Windows XP on the Intel based dvx500t Series
I have installed all the drivers mentioned in the thread and I dont have any "yellow" marks in the device manager...
The problem is With Vista there was a toolbar option that displayed "battery level", "charging status" and allowed to use the following settings
1)Power saver
2)HP recommended
3)High performance.............
