Hi Appolon,

Dell recommends applying A19 update during your next scheduled update cycle. The update contains feature enhancements or changes that will help keep your system software current and compatible with other system modules.

But as you said the present version of BIOS in the system is A13, I recommend doing a BIOS update step by step by updating from A13 to A14, A14 to A16, A16 to A17, A17 to A18, and A18 to A19.

Click on the below BIOS version to update BIOS:

BIOS A14

BIOS A16

BIOS A17

BIOS A18

BIOS A19

  • During BIOS update verify that the computer is connected to an AC Adapter.
  • Disconnect any third party peripherals connected to the computer before performing BIOS update. 
  • Do not turn off the computer during the BIOS update.
  • Do not restart the computer during the BIOS update.

Note: Plug your computer to a good, working walljack before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to buy a new BIOS chip or buy a new motherboard.

Also, you have posted about USB 3.0 Ports loose. Is it not working or is the port loose on the computer?

Awaiting your response!

Thanks & Regards
Rajesh R

 Rajesh  Really thanks...for your "so quick" response.

   The "problem" with usb3 ports I had from when I bought the laptop.
....During the time I'm working suddenly I'm loosing the port.
 Most when I am using both ports. Then, sometimes the system find them again,
 other times I have to unplug...reboot..and then is o.k again.
...Few times I have to reboot many times...and become..difficult to have the system stable.
...This last case it happens most when I have plug in many usb devices (with a hub)

  Now I am planning to update drivers and (maybe) to clean install W7.
 I am little "afraid" for what I'll face because it'll be the first time I'll do this procedure.
  Also (for to be honest), I read so many posts from people complaining for compatibility issues...
 and problems with drivers and bios and more...that I "got"... "paranoia"...
  Anyway....I made recovering disks and a W7 image so I'll give a try.

   About the bios now.
  Please please...let me understand if you know a) why is good to follow this order you suggest?
 I mean A14, A16, A17..etc ?  Is the first time I hear something like this.
  Also I read many posts that they destroy their systems with A14 version. Not compatibility in drivers and more..
 Did they fix it? I know nothing about, I'm just asking.
   Also if I clean install W7, will I have to update bios before or after the installation?

   Please answer to all my question...(in what it helps the bios series..etc.) is so important to know what I'll be doing..
 because "somehow", now is o.k my system...and I'll feel very stupid if I'll make it worst or unbootable!

   Thank you so much....for your time, for your patience, ....for answers...and I'm sorry for "poor" english...

Hi Appolon,

Every release of BIOS would have Fixes & Enhancements. Sometimes BIOS update mighty fail asking you to install the previous version in sequence.

Before reinstalling operating system, click on the following link to for few more troubleshooting’s for USB drive:

@Appolon

"This last case it happens most when I have plug in many usb devices (with a hub)"  

 

Is it a Powered or Non-Powered Hub? You are aware of  limitations and constraints on USB Ports as well as the USB Root Hub based on total power consumption of the devices that are connected. Also, cable lengths used between devices and ports are another limitation that will affect the USB Ports. All this and more you may have passed the limitations thus the reason your USB ports are having issues. Including what you are seeing, the USB Port recognition is being dropped .

Here's a good source of information in regards to USB 2.0 and USB 3.0 - 10 things you should know.

Thank you Rajesh for reply.

  I'm going to read everything you suggest.

The page from microsoft looks very helpfull, (the rest Dell's pages I knew already).

 Thank you for explanations about bios. They help me to understand why I'll be doing so...

(I know sometimes, we make you tired with "simple questions".., but you could excuse...if you

think that often we are getting so "different and opposite" suggestions...which bring "confusion"..

 An example that you understand. For the "correct order" installing drivers for xpsl702x

Others suggest for first -Dell's support soft., others -chipset Huron River, others -Chipset Renesas...

 and all is here in Dell's site!...)

  I'll mark thread as solved. I have another thread about languages

-support forum > microsoft Os > about lang.  

  If you know about, you could give me any "idea"...what I have to do, because nobody answer me.

    Thank you so much for your time. I really appreciate your good will.

CyberMaxX360 thanks for reply

  Really interesting - usefull - special informations!

I was looking some informations from usbView (debugging tools),

but the way of "investigating" from this site is much better.

 I didn't know about. Maybe I'll not need to reinstall windows...

Thanks for time. I'll mark your answer too.

Id suggest you undoubtedly re-install your'e operating system from CD.  with A13 Bios. got to Dell website and download A19 Bios. install that, it'll ask you to close all programs before continuing. after click "Ok" after it is complete it restarts your'e computer and you now have A19 Bios. 

Dell Latitude D630 

Bios:A19

Ram 4gb DDR2 2.20hz

I want to upgrade mine to 8gbs of ram but its pricey, also need to upgrade my cpu to at least 3.0ghz if laptop can handle which I heard it can. Id be happy with 2.50.. mom has 3gbs ram 2.50ghz and it runs smoothly on a Inspirion 530s Desktop PC she just got 2 years ago. 

(BTW.. not bragging just happy got computer to what I want so far. Id advise buying some more ram and cpu and computer will move quickly with that A19 Bios update.)

RE: Bios update from A13 to A19

Seems i am very late to advise you on this

but just recently i have  flashed my BIOS from A13 to A19 and everything seems  okay so far.

 the write down was successful but screen kept blinking for  20 minutes without a boot up so i shut it down forcefully

 after that upon reboot it was normal, nothing has melted or destroyed

later upon intsall of HD audio driver, system did not boot normally after a forced shutdown and two  window safe mode  boot up, it was again normal

 so keep XP with you

as there is no Bluetooth driver for window 7

Hope you understand, after all it is a legacy machine.
