• Compaq Presario F700 laptop - replacement of Ethernet (NIC)

  Hi all!

  I have recently switched to my laptop to XP. I had the hardest time finding drivers for the LAN.  So I finally found them and now the connection is always limited or no connectivity when connected via ethernet.

  I tried to release and renew the IP address, but the system is unable to renew it through CMD.  My internet works fine with my other two computers.  I used the same ethernet cable connected to this computer to my laptop and they are all lead to limited connectivity or not.

  I think that the NETWORK card must be replaced, but I can't find the replacement part number.  I don't see the number for the WLAN.  Could this be the same room?  I don't think so, because the wireless is fine, it's just the connection to the LAN which I seem to have a problem with.  I see not even where I can access the bottom of the laptop ethernet card.

  I received the spare part of this thread - http://h30434.www3.hp.com/t5/Notebook-Hardware/Compaq-Presario-F700-Laptop-NIC-Replacement/td-p/1639...

  Anyone know what part I need to replace the LAN ethernet, not wifi adapter?  (unless they are the same, want to make sure before order).

  Thank you!

  Hello:

  To replace the ethernet card, you will need to replace the motherboard together.

  The link you mentioned (which I answered the way back when), was to replace the wireless network card.

  I recommend that you just buy an adapter USB to RJ-45 ethernet until you buy a new PC.

  If your laptop has an amd processor, XP driver you should use.

• My laptop turns off itself Compaq presario c500

  My laptop turns off itself Compaq presario c500

  This may be a problem with the power supply for laptop. Power drain the computer once and then check to see if the same problem still exists. In order to drain the computer, disconnect all external devices from the computer and also to take the charger and battery, then press on and press and hold power for 30 seconds and release.

  Also a BIOS update if available on HP.com for model laptop.

  You can also see the computer in BIOS. Power on the computer and immediately, press the F10 key to load the BIOS, and then leave the computer as it is in the screen of the BIOS for some time and check if the computer turns off again and if it still cell phone off on its own while it is in the BIOS then contact HP and arrange for the service on the computer

• Compaq Presario 2586US laptop - hard drive upgrade

  Recently, I took a chance and bought 2 'parts only' Compaq Presario 2500 laptop computer series off Ebay and was able to make a unique work PC with motherboard of the 2586US being the motherboard, I used.  I don't have a hard drive, so I bought a Samsung 160 GB ATA drive.  Turns out I have to not need the adapter on the end of bus because it plugged right in the motherboard making.  The reader is supposed to be ATA100 and ATA133 at the upper end (I don't remember which).  I put the drive and installed Windows.  I noticed that it seemed slow but Windows showed the disc to the original format.  Then I went to dual-boot with a Linux distribution and encountered errors.  Thanks to a lot of research on the web I found the BIOS and the IDE interface itself (?) apparently does not have a drive larger than 137 GB.  I checked the BIOS and indeed it says the maximum usable size 137 GB.  It also shows the transfer rate to DMA2, which, as I understand it, means that it is only the transfer to 33 MB instead of 100 or 133 MB.  The service manual says ATA100, so it should support a transfer DMA5 rate.

  I don't pretend to understand all of this at all.  So, I'm looking for help.

  (1) is anyway to go beyond 137 GB on a hard drive in this laptop?

  (2) otherwise, it's the fact that my drive is actually 160 GB when the PC support 137Go cause more problems?

  (3) what should I do to obtain a rate of transfer beyond DMA2?  The configuration of the BIOS doesn't let me tab this field to change.

  Thanks for any help and explanations that I can understand.  Don't forget that I am just your average Joe and not some kind of expert at all.  I found a lot of this on the web but don't know what it means.

  Thanks in advance!

  After a lot of research and reading on the net, I found the following link:

  http://wwwcsif.cs.ucdavis.edu/~leeey/A7A266/

  Basically, the driver ALi M5229 was the problem.  It was not really support the DMA modes.  The link explains this and provides a link for the driver of the UDMA for the chip (it is not only the miniport driver that you get from the Compaq/HP site).  I installed it, had to reboot about 3 or 4 times due to messages "new hardware has been installed, but a reboot is required.  When I finally got around those I noticed that in Device Manager I see the ALi controller and it is listed as a UDMA controller now.  The individual channels are not displayed (the pilot seems to configure the drives as SCSI peripheral nickname).  Using the included ALi utility, it shows my driver running at ATA100/133.  Startup, everything including startup items until my office is there, the system's busiest has been reduced to about 1/4 or 1/5 while she was before.   I have a new system of hearts for my office, so sometimes I think that it still seems a bit slow, but there is a world of difference between a modern quad core system and this old laptop P4 architecture, etc..  But okay, the laptop works fine now in Windows.  Now I'll have to see what it looks like for Linux, because I have no idea what it uses for the driver ALi M5229.

  I think we can safely call this thread closed, how ever do you that.  Somehow, I thought she was going to be a bit obscure, and I guess you can say it was!

  Thank you all for any help here!

  Make sure that your antivirus program is disabled. It should be in safe mode, but check to be sure.

  If the antivirus program is active for a windows-based BIOS flash, the antivirus program may try to interrupt the flash 'think' a virus attacks the BIOS. A BIOS flash interrupted computer = death.

  Hi Hilary

  It will be interesting to know what model of laptop you have. When you start the import procedure is the use of the CPU to the maximum? Can you please check it in the Task Manager?
