• HP Compaq Presario CQ40 330TU: BIOS password

  Hello

  I have a laptop Compaq Presario CQ40-330TU 10 Windows (32 bit) operating system. I seem to have forgotten the password to the BIOS of my laptop. I entered the BIOS password three times, whenever I entered the password, it said "Incorrect password". At the time wherever I typed the password for third time, he showed the number of the key as 56573544. Could you please help me in resetting the BIOS of my laptop password? Any help in this regard will be highly appreciated.

• which processors can take a motherboard supported very 4101p (494035-001) jal50 used on compaq presario cq40?

  I have a compaq presario cq40-142tu, with a celeron t1600 installed. I want to replace this with a faster processor but can't find a site that lists all the processors that are compatible with the motherboard, which is a worm of 4101P jal50 1 or 494035-001.  as the celeron t1600 has a front side bus at 667 mhz, I guess procies upgrade as possible would be a t7600 to better or at least a t5500, since these procies run at the fsb even.  any advice on where to find a list of processors supported for this motherboard would be much appreciated.

  It took some time, but I finally got my hands on a t5850.  Installed and it works like a charm! a celeron t1600 it is now on a core 2 duo procie.  also improved the hard disk in the series hitachi 160 GB 5400 RPM to a 640 GB 7200 RPM samsung. also changed the RAM of 2 GB (1x2Go) tech of micron for gskill 4 GB (2x2gb) RAM.  OS is win 7 ultimate 64-bit, standard was vista 32.  one thing I noticed, though. the Rams are running at 667 mhz even though they are valued at 800, and I have absolutely no idea on how to change this. Publication of the research on some more and I think that the jury can also support 800 mhz fsb procies, might try that also later on. So far I am very satisfied with the improvement. Oh, to be on the safe side, be sure to upgrade to the latest version of the bios. mine was initially f.14, not f66a. problem solved!

• Compaq presario Cq40 604 - tx: when the driver for windows 10 will be available for compaq presario Cq40 604 - tx?

  I want to improve my windows 7 to windows 10 but the windows 10 driver is not available for my computer compaq presario cq40 604 - tx.when driver windows 10 laptop will be available for this laptop?

  I think that HP has released/posted drivers for all models that will be supported. All have support do not at this stage are not likely to see them.

  Windows 10 includes a large number of drivers for the hardware older - but no way to know for sure before the upgrade. I'd certainly do Windows 7 recovery discs before you perform the upgrade.

• Improving RAM for Compaq Presario CQ40 - 144TU

  Hi team,

  I use a laptop Compaq Presario CQ40 - 144TU, Windows 7 32 bit. I want to upgrade RAM. But I don't know exactly what kind of RAM is suitable and the range of the RAM expansion (with the specification if possible). Please help me.

  I have attached the image of my report of PC "crucial.com.

  

  Is it possible for me to upgrade to 8 GB.

  Thanks in advance.

  Kind regards

  Santini

  Hello

  From the Crucial scan your machine accepts 8 GB of RAM and currently there only 2 GB in a slot, another beach is empty. Now, if you want to:

  (a) be upgraded to 4 GB if you want to keep the OS, you have to buy the 2 GB of Crucial, 32-bit

  (b) if you want to switch to 8 GB, no point (sorry my typos on my previous answer) to maintain 32-bit Windows. You can buy 2 x 4 GB, you also need 64-bit operating system and 32-bit to 64-bit are a clean install, not upgrade.

  Kind regards.

  Make your Vista recovery cd/DVDs if you have not yet discovered it here

  Your model should ICH9 sata driver sliptreamed in the installer CD of XP. If you did it right, you'll BSOD error.

  Use Nlite to sliptream ICH9 sata driver.
  A good guide for driver sata sliptream, here

  Note: do NOT use this guide sata driver, your sata driver is below ICH9.

  ICH9 sata driver,

  The pilot lies in iaAHCI.inf and is called ICH9M-E/M SATA AHCI Controller, here

  Download nLite, here

  Some suggestions to avoid problems when installing XP:

  1 try NOT all wake sata drivers, use only ICH9--> ICH9M-E/M SATA AHCI Controller

  2. use of XP - SP2, much easier to use since many XP drivers were built based on XP - SP2.

  3 burn the installer of XP slowly and do not use the maximum speed, sometimes it create errors

  4. choose a reputable support CD, not the one at little cost.

  Go into Device Manager, expand graphic cards by clicking the triangle to the left of the device. Windows 7 snipping tool to capture screen and post it here. Once you have done this, we will be able to see what is installed as your graphics card. You can also use the DXDIAG command in a command-line window to know who.

  The following image shows some CQ40 notebooks have an AMD graphics cards installed. We need to see that you have.

  

  Download and install the correct version of Windows 7 to the Intel Graphics Media acceleratormay solve the problem, if there is no discrete AMD card in your laptop.

  It's the Windows 7 (64-bit) version of the driver

  This is the version of Windows 7 (32 bit)

• Satellite A100-649: battery no longer works

  Hello

  I bought a Toshiba Satellite A100-649 in June 2006.
  Now, 3 months later, the battery no longer works.
  Toshiba Powersaver says it's 94% of the power,
  the LED shows that it is loading but it hangs just to 94%.

  Well, I don't care if he could not load 100%, but this is
  What makes me angry:

  If I don't have my power adapter plugged in, it does not work
  more. It does not start up or anything. Nothing works.
  No LEDs + flashing, nothing.

  Now what is that? I mean, this laptop is like 3 months
  and the battery is already broken. A laptop without battery work
  It's like a computer desktop-computer without a monitor or something.

  So, maybe somebody has experiences like that or any ideas what I could do
  (except the assistance of Toshiba or bring it back to the shop where)
  I bought it, that's what I've done - nothing so far, nor in the store
  (or Toshiba).

  Welcome,

  Codec

  Generally, the warranty covers the battery for about a year. So in your case all repairs and replacement will be free.
  In your case, I recommend to contact Toshiba service partner in your country and explain the guys the situation.
  I m 100% sure they will help you.

  I don't know if service point will have the entire notebook or only the battery broken m.
  But these details you could discuss with the technician.

  Good luck

  My brand-new satellite M70 battery no longer works. I haven't used the phone for about a week and when I tried to start it (on drums), he did nothing. The battery was still charged (63%) I need to connect the power adapter to make it work.
