HP/Compaq :: DV5tCPU Downclocks While Charging
May 3, 2009
When I use my DV5t off the charger I typically put it in power saving mode which downclocks my CPU to 0.80 GHz. However, when I plug it back in and change the power plan back to high performance, the CPU remains locked at 0.80 GHz while my battery is charging. The CPU remains locked at 0.80 GHz until my battery reaches roughly 85-90% charge, and then the CPU kicks back up to the full 2.40 GHz.
This can be quite annoying when I want to play a game or watch something in HD because I have to wait for the battery to charge if I don't want stuttering.
I figured it was an advanced power plan setting under the Processor Power Management tab, but everything I have tried has not fixed the problem. I have also tried searching through the forums, but have found nothing relating to this problem.
what is causing my CPU to downclock?

Just got in a M4400 for a client and it looks like it will go back.
It has the nvidia 770 and a X9100 3.06ghz chip and it downclocks. It seems the fan is not powerful enough to cool the nvidia chip at full speed.
Not even overclocking, either.
Gets up to 97 degrees C, and then throttles the card back to cool it off. Fans are running at 100%. If you're considering this system, and want a X9100, don't plan on too much 3D. I get downclocks in minutes in Crysis.
I have tried both Dell and LaptopVideo2Go drivers with no difference.
This is a shame really, as this is a really nice, well made laptop. The LED screen is fantastic. But downclocking indicates the cooling system is not up to the task and so this system will be going back.

I have an older Inspiron 6400 (looks like the 1505) that isn't charging the battery. The bios indicates that the battery is charging, and that it is performing normally. There isn't a red flashing battery indicator, but when the laptop is powered on there isn't any "green light" indication of the battery, either. The AC adapter performs normally ( Charger is a PA10 (90watt) and it works fine on my D800, and charges that battery normally).
What I don't understand is why the BIOS indicates the battery is charging and that the battery is performing normally. However, when I have the system up and running there isn't a green battery indicator light on the button strip. Let me clarify that statement. During the initial boot phase of start-up there is the green indicator light on the button strip, but as the OS finishes loading this light goes out and the battery doesn't charge.
Could this be caused by a faulty Bios update, or is it something with the battery charging circuit of the motherboard? The laptop operates normally when using the AC adapter, just no indication of the battery charging when the OS is fully loaded. OS is Windows XP Pro (SP3).

My Laptop is 1 year and 5 months old. There are 2 problems I am facing with my battery:
1) When it is charging, at around 86% level, it stops charging and I see an orange light blinking at the battery icon and it continues to blink unless I turn the power off and allow the battery to discharge for a while.
2) at around 45% to 50% level, the battery level suddenly drops to 7% level and then I have to charge again.
Because of these issues I now use my laptop as a desktop. It is always plugged in and I use the option of "Stop Charging" in the windows power settings. how to solve the problem.

I have had my Dell Inspiron 1525 for around two years. For the past month, when my power supply is plugged in, the battery does not charge. It has been stuck on 3% and will automatically shut down when unplugged.
I have seen that this is a very common problem, however, when hovering over the battery icon it says: plugged in, CHARGING, where as all of the other posts that I have seen say: plugged in, NOT charging.
I have tried taking the battery out and restarting but this did not work. I also drained my battery and tried to recharge but again, this did not work. My initial thought is that I may need a new battery but I just wanted to check first.

I have just encountered a problem with my Inspiron 7520 laptop. The laptop is plugged in and notes 'charging'. Problem is that it is not charging and battery has been at 0% for a week now.
Battery meter notes the battery is charging and that the battery is working normally. I have run the 'My Dell' systems test and it failed on the battery with error code WBT02-GX1...

When i plug the laptop in the charging light flashes on & off. It's not the power outlet, i tried more than one. How can i tell if it's the brick or the laptop that's causing the problem?

I just wanted to ask that can I use my laptop when it is charging i.e. connected to AC mains? Some people say that doing so reduces the battery life. Whenever u have to use it on main line, remove the battery and then use. But its too cumbersome 4 me coz most of the times, I use it at home where ac line is available.

Is there like a sign to show that it is fully charge... because when I leave my DV6-1253ca to charge overnight, the little light beside the power outlet stays on the whole time. I read the user manual and it says that if it's done charging the light will be off but I left it overnight and it still stays on.

I recently got my HDX 16, however since a few days ago it has been charging extremely slowly. Ie. If I plug in in the early afternoon, it will take until night time for it to finally reach 100%.

I plug in my adapter and it turns on and all is well once I put it in the charging port to charge the battery of my computer the adapter shuts off immediately. The charging port on the computer is slightly cracked from a fall about a year ago but it recharged perfectly fine until now. I've had 2 other adapters go out on me the original and an aftermarket and now this one is acting up on me. After a bajillion trys if I get the charging prong at the exact right spot it'll charge the battery if I push it in too far it shuts off etc.... Is this a circuitry connection problem? Does it have something to do with the cracked charging port? Is it an electrical short? Is it another bad adapter? Is it a bad battery? Is it a bad "charging board"? Which of these is most likely the case?

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?

I made an impulse buy while i was there a new HDX9494NR . Anyway ive come back to Ireland to discover that the battery refuses to charge .
Ive installed 7 on it to see if an os change would help but its the same as the factory os .
Im not sure if this is just a simple dud battery or a problem with the laptop .

i have a pavilion 2400 which i had sent in a week ago because there was no video. i guess they changed the motherboard, but they fixed that issue.
however, ever since getting the laptop back, the battery doesn't fully charge. only goes up to 66%.

i have my computer (win 7) set to high performance. I also keep it plugged it but it hasnt been charging my battery, its down to 35%. Does it have some sort of a cycle function where it waits until the battery is drained and then charges it back up? I dont want it to do this because when i need to use it on the go i would like a full battery.

laptop charging problem.
In order to charge the laptop battery, I "must" have to shut it down for around 3-5 minutes. Then it starts charging (and if i boot up after 5 minutes, then it also shows charging with charge %age increase in Windows).
But once I unplug the charger and charge it again in the Windows environment, it doesn't charge (Windows shows charging but the charge percentage does NOT increase).
Strangely, In order to charge it, I have to just shutdown it for sometime and then restart.
Its like Maybe some component or battery getting too hot that if i Shutdown, then it cools and starts charging and life is normal; but if it's too hot, then it doesn't charge.
All the LEDs of charging/AC supply are showing fine. If I remove the battery, then I can easily work without trouble on AC supply. The situation seems to be the same on Ubuntu Linux as well..
I have experienced this problem on two different machines now. It's just very strange.
Should I buy a charger with more output watts or something?
My specs are:
HP Pavilion DV-5T 1017NR
P8400
NVidia 9200GM
Windows Vista Home Premium 64-bit
Do batteries have refractory periods .. seems like mine one has

I've been having this really weird problem with my charging my laptop lately. I can't pin down the problem, whether it's the battery, the Jack or the AC adapter.
Basically, when I charge my laptop it will stop charging at random. But then If I plug the AC adapter into a different power outlet (or wall socket) it will start charging again! But then once again after a short (or sometimes long) period of time it will stop charging. Then, stranger again, if I switch back to the original power outlet I was using it will start charging again.
This problem is just repeating itself and sometimes I have to search for a socket until it starts charging again. It has me pretty frustrated at the moment because the laptop is new since Nov. 2008 so it's not even a year old yet.

I've got an HP Compaq nw8240 and when I move the mouse over the battery icon it says Plugged In, Not Charging. It only shows a 40% charge too, and if I unplug the AC adapter the battery will drain and then recharge back to 40% again.
I'm running the latest version of Windows 7 also.
I've also tried updating the BIOS but when I download the file from HP's support site it and run it all it does is restart my computer and nothing changes.

Battery will no longer take a charge. I can use a different adaptor and I have the same problem. I can take the battery out and re-charge it in my Presario v5000 without any problem using same power brick. ergo no battery or power brick problems.
HP will only run on battery power. When power is plugged in green lite flashes and battery icon says it is charging, but it is not.
It will not run on AC.

I bought this HP Pavilion DV6-1160en laptop about 4 months ago and it was working wonderfully until recently. The problems started a few weeks back when I was playing NBA 2k9 and the screen started going dim and back to fully lit and back to dim every 20-30 seconds...
I rebooted as I expected it to keep doing that even with the game off.. and when it came back on it worked just fine. There are no problems with it until I start playing a game (any game, not just nba).
When playing I kept an eye on the light next to the charger connector and that was blinking along with the screen... so when I got annoyed I just changed the battery settings to keep the screen fully lit while on battery.. until a few days back the laptop went to hybernate in the middle of me playing a game because the battery died (although the charger was plugged in and the light on). The battery charges to 100%, holds a solid hour and a half, HP battery check rates it at 'good'..

My E1705 battery refuses to charge. I had a bum power adapter which I had replaced. Got the new one today and it still won't charge my battery.
What occurs is that I plug in the power and the battery icon in Win7 indicates it is charging. The charging animation in Win7 continues until your battery is charged. But in my case after about 30sec the animation stops, and show a quarter charge and never fully charges.
This indicates a faulty battery I'm assuming? It wouldn't be the power port would it?

My AC Adapter isn't being recognized by my system and won't charge my battery. Windows installed a couple updates recently, but other than that
I can't think of any reason that it would be doing this... Its the same adapter that came with the system, the only one that I've ever plugged into this computer ......

I recently got the dreaded "Plugged in, not charging" message in vista of my Dell XPS 1530.My laptop is out of warranty .I tried all the methods suggested and flashed the bios to A09 from A12.I also checked the BIOS and it says
Battery Charge = 6%
Charger = 90W
Also when I connect the charger the charging light would flash for 5 sec. and then go off.Due to this the battery charge has moved from 6% to 7%.
I cannot buy a new mbd worth $500 . Any other cure for this ????

The case has been falling apart and now my battery is not charging.
Are all dells complete wastes of money like this? My much cheaper Acer outlasted this hunk of crap.
Anyhow, according to the computer my battery is dead and needs to be replaced, but why the hell does the battery have such a crap life? or is it something else? This laptop has spent 90% of its life on the A/C charger

Had an E1505 for a few years now, and with the exception of a HD failure/subsequent replacement, it's been absolutely great.
Recently though, it gave me the error message "adapter not recognized, blah, blah, blah" message upon POST...
Tried a different adapter as well, but no luck. It runs off the adapter(s) just fine, but won't charge, so I'm permanently attached to a cord until I get this fixed
