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.
View 6 RepliesMy 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.
View 4 Replies View RelatedI'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 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.
View 8 Replies View RelatedI'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...

So I've been using the Dell E193FPp 19" lcd monitor for a few years now. It is a lower end model (not ultrasharp) that I purchased 3 years ago. I'm not sure if it's because of aging or maybe I'm becoming more picky, but I've noticed lately that the brightness on this monitor simply is awful. White looks dull and greyish. I have the brightness at 100 and I'm really unhappy with the way it all looks.
Is my issue to do with my monitor being old, it being connected to a Dell Dimension tower that is 7 years old, a VGA connection, or something else? In the past 2 weeks I've done a lot of research and learned about VA and IPS panels. I've love to purchase an IPS panel but I fear it won't be a big improvement because it would be attached to a old Dell tower. Is this correct?
I wanted to get a new mac mini but they were not released at Macworld last week. Any suggestions or thoughts would be appreciated. The white on my monitor is a joke compared to my macbook pro at it's highest bright setting.
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 very annoying problem with hot keys for adjusting monitor brightness! After last version of hot keys driver they don't work. I can't increase or decrease brightness! Pressing them down and can't change anything. And there is something more! For example I have adjusted some level from power manager and everything looks good until I don't try to manage brightness with hot keys. I doesn't matter if i want to increase or decrease brightness, it just goes to maximum level!

I started using my laptop on a slightly darker room in the last few days and now its giving me headaches since I cannot reduce the brightness.
I can't change my monitor's resolution and the screen brightness after I upgrade the windows from windows 7 ultimate to windows 8.1 pro build 9600I've already installed graphic card , but i can't change my resolution more than 1024x768 My laptop is HP 431 with intel core i3-2310m CPU @ 2.10 GHz , AMD Graphics HD 7450M , DDR3 1 GB (i don't know why , but i've already installed AMD Graphics HD 7400M Series because my notebook isn't compatible with other AMD Graphics) , OS 64-bit
I think this is the problem [URL] ....
I got my HP DV5t about 4-5 mos. ago. The graphics card which is a 9600m GT is definitely starting to fail. When ever I start to play graphically intensive games like COD4 or CS 1.6 the screen begins to freeze and the computer says the display driver failed while other times it causes a BSOD. This used to happen occasionally about 1-2 mos. ago but now it happens very often. I updated my drivers as soon as I got the laptop and always lifted the back for better airflow while gaming but apparently it didnt help.

i tried using an external monitor and the monitor refused to turn on from standby, a safety feature of the monitor. the small card in the underneath with 2 wires leading 2 the monitor, (i assume that is the laptop version of a graphics card) is fine, inserted properly, and i had a slight issue with the plugs fitting, but that was soon resolved.
I have an HP DV 6000T. I just bought a HP Elite M9510f Desktop from HP.com, and I don't have a monitor yet, so I am trying to connect my Desktop VGA to my Laptop VGA in and use my DV6000T as a monitor.
I also have a Sharp TV which I tried using as a monitor but the thing keeps flashing the Power and OPC lights and won't let me see anything.
Anyway I can make my Laptop monitor work with my desktop for the time being?
I just discovered an interesting issue after undervolting my DV9700's CPU and overclocking its graphics chip but forgot to post it earlier. When playing GTAIV (which is extremely GPU intensive as you know), the whole notebook will get warm. I already know from FurMark that my 8400M GS will reach 80C in its current configuration so i can understand why the thing gets warm. However the fan always runs at minimum speed when playing GTAIV...
This leads me to believe that the cooling fan is exclusively controlled by the CPU temperature. It wouldn't matter if the graphics chip would be on fire - the fan will still not ramp up unless the CPU reaches the temperature threshold. I'll check exactly what these threshold values are later, but i remember that on my DV5 it's 75C for high and 85C for maximum. The fans on these things have 4 speeds IIRC.
Now, my DV9700 is a large and rather solidly built machine. It easily copes with the heat even with the fan turned down, i have no issues with GTAIV or any other game, and if you recall it had a faulty fan when i got it yet it was still able to work for 20 minutes before reaching shutdown temperature.
But if this is true for all laptops, i can see why these GPUs fail. Notebook manufacturers should consider implementing a fan controller that reads from both CPU and GPU sensors.
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 presario 1500 with a pentium 4 running XP SP3 on it. I am having trouble with keeping it under a good heat, the fan is constantly running high! i know this needs a good clean but the screws to remove the back casing are so small for me to do this! any suggestions of how i can clean inside? or get to th fan through the top by the keyboard?
secondly it tends to crash every now and then, maybe when it overclocks on the cpu?? i am recently trying out a program called speedswitchXP which seems to be slowing it down to an extent! but not solving the issue.
thirdly and finally, my battery only holds charge for around 10 minutes before needing constant wall plugin! i constantly have it plugged into the wall, could this be a result to any of my problems?
got a Presario V2000 that will not boot whatsoever.
Upon pressing the power button, the machine starts up and displays the standard "Windows could not start properly" screen. Every option I choose, from the three Safe mode options, to the Last Known Good Config, to Start Windows Normally will not work.
I choose an option and everything goes smoothly, the Windows XP splash screen pops up & stays there for a few seconds, then goes blanks for a slightly longer length of time before a blue screen pops up. I can't remember the first few numbers, but the rest I'm pretty sure is accurate:
(a series of letters/numbers is here) (Registry File Failure)
The registry cannot load the file
SysCommandSysCom32ConfigSOFTware
or its log or alternate
It is corrupt, (something I cant remember), or not writable
Beginning dump of physical memory
Physical memory dump complete
Contact your system administrator or technical assistance.
.....and it pretty much repeats over and over in a continuous cycle like this until I power it off.
What I'm wondering is where exactly the problem lies? On the Hard Drive--where the drive itself needs to be replaced or the OS just wiped and reinstalled fresh.......or is this indicative of a hardware failure...which would mean this lappy is pretty much dead?
On pressing start button, laptop starts, but blank screen comes. After every few seconds, it keeps on rebooting, but nothing happens.
I have tried pressing F10 and Esc button on startup, but nothing happens.
Moving finger over multimedia touch buttons causes them to beep.
Few times, it shows the BIOS, but does not detect the hard-drive.
Very rarely, everything works fine and OS boots and works fine (without any sign of problem).
I replaced RAMs, hard-drive and DVD Reader in other laptop and there they worked absolutely fine.
I even tried removing the battery, connecting external monitor, keyboard, but nothing worked.
BIOS version is F.3D.
When opened, CPU fan and heatsink were dustfree.

I have a Presario V2000.
After not using for about 1 week I turned it on so I could clean it from viruses.
Got the battery alert and then it shutdown meanwhile I was pluging the cord in (Targus AC cord with
blue light).
When I connected the AC to the power (not connected yet to the laptop) it "turned on" and still today
shows a blue light. But once I plug it to the laptop the blue light disappears after 3-5 seconds!
Not at the beginning nor the end of this process the laptop will turn on if I press the power button
for 'x' seconds. If I plug the cord, the computer doesn't show any "power light" and then the blue
light from the Targus AC fades off.................
I have a Compaq presario C500 laptop by HP....
When I bought this computer these are the specs:
***Processor: 1.6 GHz
***RAM: 512 Mb
***Video: Up to 64 Mb Shared...
***Battery: 6 cell Lithium battery...
***Hard Drive: 80 Gb STANDARD
What I changed to:
***RAM: 2 x 1 Gb = 2 Gb total RAM...
***Hard Drive: 250 GB 7200 RPM.....
I am so much happier with this notebook than I was with my Presario C714NR.
Why;
Upgraded Intel GMA 4500M 768MB Max VRAM VS. 384MB on C700 GMA x3100
Upgraded support for 8GB Max Memory VS. 3GB with the C700 **Some G/CQ's can only handle 4GB
15.6" Screen not really a big deal from the 15.4" C700
HDMI Port VS. none on the C700
Media Card is standard in the G series.. VS. optional in C700 series.
Discrete Graphics offerings available for the G series and CQ-Series VS. integrated only C700
G/CQ offers shiny black top finish. C700 More grainy finish.
Better gaming performance, however, not really a gaming laptop.
HP has made some great improvements to the Compaq offering, however compaq will always lack some of the premium features like FingerPrint reader......
