• 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

  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.

  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.

• Support for the decommissioning of my compaq presario cq40-109tu...

  I really wanted to downgrade my laptop to xp because there a pre installed in vista, but I really don't like vista... That's why I decided to downgrade it, but I'm worried because I need tha drivers are compatible for xp (wireless adapter, bios, hidden, etc.) I browesed most of the forum but I'm not sure what wich and are not the right drivers for my laptop as well as the thing of nlite can you guide me in this regard? I think mine is also SATA... Thanks in advance for the answers and help...

  I'm not in the same impression that you have for Vista, in some points, I have found that VISTA has its own advantages.

  Given that your model has been built for VISTA, some functions may not work IE adjusting brightness (Fn + F7 or F8)

  However, you are not alone, many CQ40 lowered their laptop.

  If you want for XP drivers try the following steps.

  You keep asking the same question... again and again and again!

  The answer will be the same - HP will not release schedules at the pilot production.
