Dell :: D620 + 4gb Of Ram = BIOS Says That Only 3gb Is Usable
Mar 30, 2009
Quick question here - just installed 2x2gb and BIOS happily tells me that "Due to the amount of memory being assigned for system use, memory available is less than memory installed".
Which works out to Task Manager reporting only 3.3GB (Vista 64).
From what i remember, it means that d620's BIOS can't map devices above 4gb? I tried to find this option in the BIOS but couldn't. Maybe i missed something? I'm kinda disappointed since d620 is supposed to be more or less serious laptop.

Has anybody tried to put a Latitude d620 ATG lcd display cover on regular D620? This seems like a simple switch but I would like to hear your opinions.

I reinstalled my D620 from scratch (ie. formatted the disk) and reinstalled from the Dell supplied XP Pro media CD. I downloaded and installed all the relevant drivers. I have Intel wireless working, the nVidia card working at 1440x900 etc ... However, I can't seem to get the power/battery management to work. The D620 shows its battery light as green when the AC power is plugged in and the physical battery button lights up all the LEDs when pressed when the battery is partially/fully charged but neither the BIOS nor XP Pro recognize the battery.
Similarly, when the AC power is disconnected the battery works fine by itself for x hours but the power cord icon remains in the the taskbar and the battery light on the laptop glows orange as soon as the power is cord is disconnected. The LEDs on the battery itself however light up when the button is pressed on the physical battery. On reboot the BIOS also does not recognize there is a battery present and not does XP Pro.
In other words, everything works as expected of a laptop - except when totally wireless, how much juice/time I have left in the battery - this is fundamental to any portable device.
A few hours prior to the reinstall both XP Pro and the BIOS recognized the battery no problem and worked accurately and without fault - so I refuse to believe this is a bad battery. Somewhere there must be a driver to enable the BIOS and XP to recognize the battery ?
The battery works and both XP Pro and the BIOS were well aware of its existence prior to the reinstall a couple of hours earlier. All I did was to format the hard drive and initiate a totally fresh install of XP Pro - and installed the drivers downloaded from Dell based on the Service tag of the D620.

I have installed a FX 2500M (rev A02) on a M6300 system board A10 Bios, the card is working but its clock is fixed to 100MHz (100MHz core + 100MHz mem).
FX 2500m doesn't switch to 3D Low mode (200/300) or 3D Performance mode (500/600).
It always remains on 2D Mode (100/100)
Off Course the same card works correctly on M90 System Board.
I have tried many drivers, DELL version and generic version by laptopvideo2go, but same results (always fixed to 100MHz).
I have tried Rivatuner to force clock switch. Same results No Switch
I have even installed a new OS (Vista 64) and with it, I have a strange situation.
With Vista64 (no SP1) original driver supplied by MS (and based, I suppose, on forceware 96.xx) the card seems to works at high clock.
No information tools can be used (with MS Driver) so I can't see which clock are active but 3D performance (games and benchmark) are near the performance achieved with M90.
But once I update the driver by installing a recent version supplied by Nvidia (Dell version or generic is the same), the card blocks to 100MHz even under Vista64.
Unfortunately with MS Driver there are many graphics error and it isn't so usable with 3D application (i.e. games) and furthermore I want to use the card with XP32 (Vista64 has been installed only for tests).

Just installed Windows 7 x64 on a new Macbook Pro with 4GB of RAM. When I go to check the specs it says "Installed memory: 4.00GB (3.72GB usable)"
Do I need to update a driver or bios?? My first thought was that it was sharing video memory, but my previous gen unibody Macbook has 2GB of RAM and all of it is usable in Windows 32-bit, none of it is shared. Both Macbooks have the same GPU so why isn't the total amount of RAM usable in x64 version of Windows?

I would like an all inclusive iphone headset that also works well for movies and games on a pc. I do not care about size, but i dont want anything to bassy or cheap sounding. I have given up on apples products, the standard iphone headset breaks way too easily on me. (THE REMOTE PART). I was also wondering where all the new headsets (the iphone one with volume control, and the high end one) are that they said would be released.

i recently bought a dell from craigslist a month or so ago and seemed to work fine, i recently installed ubuntu on it, i dont know if it has anything to do with my problem but anyways...
problem started when the laptop would shut off unexpectedly, but would start right back up fine.. i think it was due to overheating im not sure if the fan is working or not bcuz i hear no sounds coming from it. it showed a screen saying it shut down bcuz of it was getting too hot twice. i opened it up and checked for dust in the fan and cleaned it up. after it shut down about 3 or 4 times while using it, it wouldnt reboot. when i push the power button the three caps lock, number lock, and scroll lock will flash as does the power light then it will shut back down. occasionally it will boot and make it as far as the desktop screen then the screen will go black, but the lights will still be on as if the computer is still running, and i will have to hold the power button down to get it to turn off.
one thing i have noticed is that with the hard drive in the laptop it will make a beep noise then shutdown, if the hard drive is out it will shut down with no noise.
i have tried everything, i have reseated the ddr memory and tried running off just the power cable or just the battery with no success.

I have recently purchased a D620 from eBay and am experiencing the following problem with charging the battery:
Battery charges normally to 29% and then charge rate falls back and charge will not exceed 31% and charge light goes off.
MobileMeter gives battery wear rate of 21%
When the laptop arrived the battery had a 100% charge but once used it will not charge over 31%.
I have tried different charger.
At 31% I can get 40 mins of power normal use.
Is the problem with the battery or internal control of the charging rate? If the latter it could explain why the battery arrived fully charged if it had been charged on another computer or commercial group charger.

I like my Dell D620 so much that I just got another one. I've heard that I should not add an additional 1G module to the existing 1G in this laptop, but rather that it is best to replace the existing 1G with either two matched 1G modules or one 2G module. Is that correct? Seems a shame to toss the 1G that's already in there . . .
Could I add a 2G module to the 1G that's already in there? I'm assuming that the bay will accept two RAM modules.
The OS is XP-Pro, SP3, if that matters.

I have a Dell D620, approx 2 years old that has been a real work horse....until recently. For some unknown reason it now does not recognise either of the two batteries I use in it. The spare one slots into the DVD bay when I need extra juice.
Now I know that batteries deteriorate around the 2 year mark but both of them on the same day doesn't seem right??? All I now get is the yellow flashing battery indicator and it only runs on mains powere.
I'm happy to buy another battery but would prefer to resolve the current problem first if at all possible - any suggestions greatly received?

Does anyone know where I can buy a D630 motherboard. I want to convert my 620 too a 630 so I can get the Intel 965 chipset. My 620 has Nvidia graphics so preferably I would like to find a D630 notebook with built in Nvidia graphics. I have checked ebay with now luck and I know that asking Dell about this would be a complete joke. Anyone know where I can just buy Latitude parts?

I have owned a Dell Latitude D620 for the last few years. Lately, i have realized that my 9-cell battery is only charging to 84% (4 weeks old), and it only gets about 1.50 hours on full charge.
Also, at random intervals, the LCD screen flickers and becomes blurry. All settings are default and there have been no modifications, here is my computer information.
Dell Latitude D620
Intel Core 2 Duo T7200 2.0GHz
2GB RAM
256MB Video Memory (nVIDIA Quadro 110)
Microsoft Windows XP Professional Service Pack 3 .....

I have a 3+ yr old D620 that I have been really happy with. It is starting to show its wear and tear a bit,
I have lugged this thing everywhere on a daily basis. So, looking at the current Dell lineup, there doesn't seem to be anything that strikes me as a similar model.
Here is what I particularly like about it - and what I'd require in a new one:
1) Pretty durable solid build, including the way the screen locks pretty much in place - i.e. doesn't feel flimsy.

I was given a dell d620 with a broken screen. Looked like it was cracked down the middle. I replaced the screen (not the lid or hinges). It makes a clicking/cracking type noise when I open the lid. No visible cracks. Now, sometimes when it boots, i get vertical lines and sometimes dollar signs before Windows boots. Windows DOES boot fine with no lines whatsoever. I have researched and found the symptoms are the same for a bad vid card. (I know this has Integrated graphics). If my card was bad, would Windows still boot and look normal? Why would it only affect the boot screen?

Trying to run a D620 with a new harddrive, a 320 GB WD3200BEVT.
The 620 will say "a read error occurred, press Ctrl alt del to reboot" directly after post. I doesn't not attempt to load an OS.
In the BIOS:I made sure that the harddrive password protection thing is all off
In the device list the 320 GB drive appears, so it's not a mechanical problem
The drive works on a modern AM2 desktop.

it's coming with XP Pro but I've been running Windows 7 here on my Dell Desktop since around February(RC/beta version then bought Ultimate version when it was released) and I have to say I like it a lot and would love to install it on the D620 when it comes,
has anyone here installed Windows 7 on their D620 and if so and have any driver problems or issues of any kind??
Thanks in advance and sure nice to be here...
