Re: replacing used up ram and installing new 1024 Ran
I beleive that I have the required answer for you...
Basically, this series notebooks either have both the RAM slots at the bottom or one at the bottom and the other under the Keyboard.
I recommend you to try removing the RAM module cover and check if there are two RAM slots or just one.
You can find the required instructions to locate and remove the RAM compartment cover from the manual of the Notebook which is available through the link below :
Better way is to copy and paste the link in the address bar of a new Internet Explorer window and press Enter to open.
You can find the instructions to remove the RAM compartment cover from page number 35 of 154 in the Manual.
If you are able to find two RAM slots, we are done, you need to remove the preinstalled memory according the instructions available in the Manual and place the two 512 MB RAM sticks you had purchased.
However, if find only 1 RAM slot, you need to find out the instructions to remove the Keyboard to explore the second RAM slot and insert the second RAM module into it...
You can find the instructions to remove the Keyboard Cover and Keyboard from page numbers 43 and 46 in the Manual.
Hope this helps....

First of all, make sure you have the right memory - 240 pin, DDR2 SDRAM, PC2-4200 MB/sec.
Your machine should support the memory as it has two banks of 1. Sometimes it is simply a sequence problem. In older machines with mixed memory, I always put the largest and fastest in the first slot. You might try just reversing the memory.
There could be many reasons,
1 Either the RAM slot is not working
2 or the RAM card(s) are not OK
3 or the RAMs are not compatable(not of the same specs)
1 Remove both the RAM cards, clean the metal joints in both the RAMs and the RAM slots
2 Remove power, remove all power source, remove power cables including all the battery
3 Keep presssing the power switch ON for a few mins, Do....ON... OFF, ON... OFF WITHOUT any POWER
4 Replace battery, power adaptor, power cables etc
5 Insert one of the RAMs in 1st RAM slot, power on, check if it's OK, Switch OFF, remove the RAM
6 Do the above process for the other RAM, now check if that works, use the same RAM slot
7 Now do the above two steps for the 2nd RAM slot
It will give you a rough idea of where is the issue.....either RAMs are not OK or the slots have issues or there is a compatibility issue among the RAM cards.....
You should be able to upgrade the CPU, since it seems that the DV1000's motherboard uses a socket CPU design. But, obviously, HP would rather have you choose the CPU that you want from the beginning and stick with it. The first thing to do is to check HP website to see what other configurations were/are sold for
your model. If they sell it with faster CPUs then you can upgrade to
one of them...
PLEASE NOTE: In order for a particular processor to be compatible with a particular laptop: (1) the processor must be physically compatible with the laptop socket, in your case I thing you have a Soket 479 processor (2) the laptop chipset must support the processor. (3) the chipset front side bus speed must match the processor front side bus speed, in your case 400Mhz. (4) the laptop BIOS must support the processor.
So I listed here processors with FSB at 400Mhz, I gues that DV1000 as a 855GM Motherboard that supports only 400Mhz with Socket 479
Banias Pentium M 1.3 1300 1024 400 Pentium M 1.4 1400 1024 400 Pentium M 1.5 1500 1024 400 Pentium M 1.6 1600 1024 400 Pentium M 1.7 1700 1024 400
Dothan Pentium M 710 1400 2048 400 Pentium M 715 1500 2048 400 Pentium M 725 1600 2048 400 Pentium M 735 1700 2048 400 Pentium M 745 1800 2048 400 Pentium M 755 2000 2048 400 Pentium M 765 2100 2048 400
Banias-512 Celeron M 310 1200 512 400 Celeron M 320 1300 512 400 Celeron M 330 1400 512 400 Celeron M 340 1500 512 400
Dothan-512 Celeron 205 1200 512 400
Dothan-1024 Celeron M 350 1300 1024 400 Celeron M 360 1400 1024 400 Celeron M 370 1500 1024 400 Celeron M 380 1600 1024 400 Celeron M 390 1700 1024 400
well, the lowest speed of those rams will be effective for all rams. If you install same sized ram on 1st and the 3rd port, it should be run on dual channel mode and will be fastest possible. please try this if you have 4 ports.
vista needs 40mb to install ...no matter how much mem you install vista is slow compared to xp or xp pro which configuered right can run at lightening speeds.
to upgrade mem ...
you either have 2 512mem cards or 1 1024 card ...if you have 1 1024 card add another if you have 2 512 replace with 2 1024.
you can buy mem cards in any pc shop.
