HP/Compaq :: C500 Battery Holds Charge But Drains Fast
Oct 5, 2009
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 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
The battery on my laptop (Dell Studio 1735) was bad, it charges up fine, but only holds a charge for about 5min after being 100% charged. Dell doesn't offer a genuine battery for my laptop anymore so I purchased a third party one for my model. The new battery works and powers the laptop, but upon booting I get a message that tells me the battery is unrecognized and will not be allowed to charge, and within windows it says that battery is "Not Charging".
Things I've tried:
Unplug battery and adapter, hold power down for 5 sec, plug everything back in. Allow battery to drain, then when booting and the message says the battery is low and should be charged Press F1 to Continue. Flash BIOS Downgraded BIOS to A04. Downgraded BIOS to A03 Searched for updates to the battery driver in Device Manager Removed battery driver and allowed to reinstall Booted up with genuine battery, then swapped out to the new battery once within Windows.
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.
Can someone help me figure out why my battery drains while my laptop is turned off and not plugged in? It started just a few days ago and I can't figure out why it would do this
I was thinking of purchasing a Dell XPS 1530 for college. I have everything customized exactly the way I want it but I was wondering if the bluetooth option was absolutely necessary for college campuses? I really do not want bluetooth in my laptop if I do not have to get it as I hear bluetooth drains laptop battery power, but is it required by todays standards?
I'm having an issue with my Flex 15. When I shutdown the device, it the battery still drains, to the tune of a couple % per hour. If it matters, I updated it to Windows 8.1.
My E530's battery drains 5% per day after power off. I searched online and somebody else complained about similar issue on his Y-series laptop. His problem was solved by plugging off power cord before turning off the laptop. Lenovo also updated BIOS regarding this issue for his model after then.
Yesterday I tried his way and the issue was gone too. Can Lenovo update BIOS regarding this issue?
I also find the power manage scheme doesn't work. It always charges the battery from 96% to 100% in whatever scheme I chose. I tried to uninstall the driver and downgrade the power manager, still doesn't work. I didn't try reinstall the system because it is too time consuming. Does it matter I installed win7 in my SSD?
Lenovo Carbon X1Bought ~2 months ago (new) at a reseller in the USi5 3rd generation @ 1.7GHz4GB DDR3 (soldered on motherboard)128GB SSD (Samsung), must be SATA III (6GB/s) I guessWindows 8 Pro x64
Furthermore: +40GB free space on the hard drive Original charger used, always . Laptop was never 'opened' (ie with screws)device mainly used to text editing, browsing and PhotoshopBackground apps/services: Apple iTunes services, Dropbox, Lenovo mouse/trackpad service and startup utilities like Google Update, Java update, Adobe Reader Speed launch.
I do not shut down my laptop most of the times, I simply put my computer in sleep modus (in other words: I close the lid of the laptop)I do play games on this laptop, but of course I do not expect the battery to last many hours when doing so. The battery drains quickly only in 'normal' situations - gaming, video editing and lots of Photoshop do not count of course.Connected to the internet all the time (no 3G, just WiFi)Bluetooth disabled.
The laptop is fully charged using the original charger. The power plan is set to Power Saver (image). Brightness is set to around 60% of maximum according to the build in indicator of Windows 8. The apps that are open are Google Chrome ( with 5 tot 15 tabs most of the time), Outlook, Dropbox and one metro apps (weather or the app store).

As you can read, no heavy usage. The CPU is stable between 5% tot 20% and the RAM is at 40% to 70%.
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 bought an HP DV6000 laptop to a friend. It was working well until now.The battery won't charge. It says Plugged in, charging, but the % doesen't go up. I've charged it for a day and it's still 0%.
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.
I just purchased a new probook 4540s core i5 with win7 x64 system.
Firstly, When battery full charged then turned laptop off for a few hours or next day it becomes 99% or 98% although its plugged in Ac power. Shutdown again for 1 hour and turn on it turns to 97%. Is that ok or there is problem in battery specially it shows that ( Plugged in, Not chareged ) so laptop should operate at AC adapter and battery remain 100%. Secondly, I have an unknown device can't find it as shown in figure below.
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.

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?
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.
I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. At least my laptop still will not make it through the night in sleep mode.
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops. Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.
My laptop (Dell Inspiron N 5110) battery goes down fast after installing/updating Operating system to Windows 10 Technical Preview, battery was working fine on windows 8/8.1 before installation of windows 10 technical preview.
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 owned a ThinkPad T430 for about one year now. Originally I was fairly impressed with the battery life (around 4.5 hours) but now after owning it for a year I am very unimpressed with it's short 3 hour life now.
I have read that batteries should be expected to do this, although I have friends with a MacBook Pro which has lost maybe 20% of it's charge over three years not one year like my ThinkPad!
My specs are listed below:
OS: Windows 8 (upgraded from 7) Ram: 8GB (4*2 DIMM - came with 4GB and I upgrade it with 4 more) CPU: i5-3210M 2.5GHZ Hard Drive: Samsung 840 Pro 256GB SSD (upgraded from the 320GB 7200RPM HDD before...if I have got those specs right)
I recently installed the new SSD and expected to see my battery life shoot up again (hopefully at least half an hour) but I really haven't noticed any such improvement.
I use the battery frequently for school and run the battery down to about 20% maybe twice a week on school weeks?
Is this kind of deterioration to be expected and should I simply purchase a new battery if I need that extra 1.5 hours?
According to the Windows 8 battery report the original full charge capacity was: 49,286 mWh, now it is: 39,780 mWh.
I have an Ideapad S510p touch Notebook that i bought just last year.But now since the past 1 or 2 weeks i have noticed that my laptop's battery is getting discharged really fast.
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?
