HP/Compaq :: C500 Booting
Mar 29, 2010
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.

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'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 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.

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'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..

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 just got my new DV4t yesterday with a blu ray drive and it's pretty awesome. However, I was hoping I could use the quickplay function so I could use less battery life and use my CPU's power only for watching blu rays without vista wasting resources in the background. But it always boots straight into Windows first and then loads quickplay second.

I've had my HP DV2000 for about a year. Recently I started having this problem. I would boot it up and the screen would be distorted like the image below. Sometimes it freezes and other times it just stays like that. I've ran MemTest to test the memory and that came out fine. I've also formatted it and started from scratch and it remains the same.

This is my second HDX 18 Laptop sent by HP in the last month. I've had this one for about a week. Everything was fine when I went to bed last night. This morning when I went to start it up it stays at the first screen (the one with the bios logo and tells you to press f10 for options) sorry if I am wrong on describing that. I can get to the Bios but I get 7 loud beeps before it enters. I am now running the system diagnostic tests on it because I have NO idea what else to do!
I don't know that much about computers so I would just ask that you use beginners terms.
now I am getting something that says "Start-up Test" Failed "Boot device not found" (3F0)
What does this mean?? ****

I have a problem with my dv9700. When I try to turn it on, it lights up in the small blue LED's, but then reboots even before I see the BIOS booting, this it keeps on doing again and again.
I've come to the conclusion that it's some kind of hardware failure, but exactly which one it is, I don't know. I tried switching out the RAM but with no luck.
Anyone here have a suggestion to what to do?
I have A LOT of very important data on the PC and I off cause have taken backups, but not recently.

I have a HP Pavilion dv4t-1000 CTO Entertainment Notebook PC and after updating my bios from F.22 to F.24 the computer wont boot into Vista. It was completed successfully using the winflash, but the computer restarted it just stays at a black screen, and wont go any further. (I hope bios is not corrupted.)
The computer is on but its not booting the operating system.
Is there any way I can revert to the old bios?
Also is there any key combination that can get it to load BIOS from a USB flash drive?

I have a compaq presario CQ61-420US with similar problems below, except I have a black screen, fan turns blinking lights are the same (num lock and cap lock) but they are flashing continuously every second or 2. I have tried the hard reset with the ram fix, connecting an external monitor, changing the battery, and the power adapter to no avail. I also used compressed air on the vents just in case was stuffed with dust since it will overheat and may cause problems, but nothing.
One option I can think of is purchasing a new MotherBoard, but I'm trying anything else before that.

I am picking up an external HD and will make a complete backup of my system with time machine. I will then install windows XP with bootcamp. I am going to format it as FAT32 so I have the ability to transfer files from mac to windows, but will that have an effect on game performance? I am mainly doing this to play black and white 2 and oblivion. I know oblivion will play well but how well will black and white 2 perform?

I received my new Lenovo Y40 Laptop - 59423025.
It comes with a Hybrid 1TB 5400 RPM+8GB SSHD.
Does it automatically use the SSD for booting? Or is there something I need to do to enable this?

Trying to update USB3 driver via various options following re-install of OS (another story/issue) - tried via the drivers CD but couldn't see what I was looking for. Back to Dell website and downloaded and 'installed' what was hopefully the right one. Re-booted, but aagh forgot to take the CD out of the drive! And the laptop entered lots of stuff via the command prompt screen and has come to a halt with a message:
A RAM DISK drive is available for this boot cycle as C.It contains several Hard Drive setup tools. Please use these tools only under the direction of Dell Support Staff. I understand the bit about Dell Support Staff, but hoped I could just exit in the normal way (exit>enter). Having said that, I don't know many command prompt entries... It's the full screen, not a command prompt window.Dell XPS 17 win7 x64.

When I press the power button, the led's around the power button will light up and stay on for a few seconds then shut off. The power led on the left side remains lit as does the BT light. If I leave it set for a while, the BT light begins to flash but thats all I get - no diag code or anything. I have already tried removing/disconnecting everything I can think of (HDD, DVD, wireless, modem, BT card, memory, video card even) just to see if I could make it give me a diag code (I know - thats getting desparate). The only one that made it give me a code instead of turning off was removing the memory completely - it gave me the "no memory" code obviously (mute light was solid, vol up and down were flashing steady). But if I put known good memory in it, it doesn't work and if I put its memory in a known good laptop I have no probs. So I went ahead and bought a new motherboard and that didn't fix it (oops). Then I found this site.
