HP/Compaq :: C500- Power- Wont Charge And It Wont Run Without The Battery
Feb 22, 2009i 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

Sep 20, 2014The exact message is Power-On Password and a symbol of a key.
I am trying to clear this Power-On Password message on a HP Compaq nc8430. Searching though this forum and on the Internet, everyone mentions I should remove the laptop battery and the internal battery to clear this password. I have do so and left the battery out overnight and the password is still there.
I have found another mention of a IC or similar that is used on laptops to be more secure. I have also found mention that some laptops can be reset by a "jumper" or by touching points on a motherboard.
HP/Compaq :: Presario C500 Fan
Feb 15, 2010My 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.

HP/Compaq :: Presario C500 Drive
Feb 10, 2009I'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.
HP/Compaq :: Presario C500 Fan Noise And Grind
Nov 5, 2009i 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?
HP/Compaq :: Presario C500 Backlight/inverter
Jul 22, 2009I 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.
