I added a 256 meg DDR ram chip in open ram bay,,computer wont recognize it,,I swapped chips,,putting new chip in first bay,,computer booted great,,swapped chips around,,still,not recognizing second ram chip,,am i doing something wrong,,went to crucial,,ran their scan,,it doesnt see the extra ram either,,thanks,,any help is appreciated.
It could be the wrong ram that u are using when i put extra ram in I make sure they are all the same brand. some boards take 2 different types of ram (speeds) i would go back to crucial with your good ram in and then do a check and see what ram your board needs

Ram should always be paired. Same type, speed and size in each slot. You may have 1 SIMM/DIMM/DDR that has 2 sides of chips and the other with 1 which will do exactly what you state.
RAM reads across the chips simultaneously. So if you have a different one in each slot it can go bonkers and do goofy stuff on you.
This usually happens when the laptop is not able to take more then a certain amount of memory, as the system BIOS does not support higher. By saying ACPI as the blue screen, that tells me that the power subsystem does not 'like' having more then 512MB of RAM. I am 95% sure this is your BIOS because of that information. Check and see if you can find a BIOS upgrade for your computer model, and that might fix the issue, if an update is available.
when working on computers you have to be carefull to ground your self before touching the inside of them. when installing memory you dont need to unpluge everythinf just the main power cord on the back of it.the blinking green light means you have something no pluged in right,double check everything you unpluged make sure it back in the right areas.on memory the slots are mark 1,2,3,4
make sure if the memory is diffrent in speeds the lagger ons go first.the first to slots normally have to be the same speed and size ram.if that does not work let me know i can look into it for you.
Supported RAM TechnologyDDR SDRAMRAM Installed ( Max )0 MB / 2 GB (max)Supported RAM SpeedPC2100, PC1600, PC2700The above is the specification for RAM for your M/board It can take up to 2Gb ram 2 X 1GB sticks you may have to change BIOS settings aand your computer will definitely run fasterPlease give me a FIXYA
First of all, make sure the ram are identical, becuase having 3 different random access memory chips in the computer can cause problems. Also make sure the ram chip is sitting in there properly. Next you should check under start go to run and type in "dxdiag".See how much memory it reports the computer has. If it reports 700etc mb,, then the one memory chip might be faulty. Also, check with the system manufacturuer, and make sure you're not overclocking the computer. Overclocking is when you put too much memory in a computer and it doesnt recognize one of the chips. 700etc mb might be the maximum your computer can handle.
its that 512 mb total capacity for your computer memory?? if so read this:
To find the total amount of RAM that can be added , subtract the amount of RAM currently in the computer from the maximum amount of memory the computer can hold. For example, a computer has 256 MB of RAM. If the maximum amount of memory the computer can hold is 512 MB, then 256 MB is the amount of RAM that can be added. this info from the HP website , to find out more , go to http://www.hp.com/support , enter the model number , and look for more information about your computer specs, hope this helps , please rate & thanks AJ
