If you have an empty slot them you can add another stick of RAM.  Make sure it's the same kind.  You can easily trade out your old CDROM for a CDROM/RW.  Just pull the old one out and replace it with the new one.  You can pick up PC parts really cheap from eBay.

The ram which I assume is what you are talking about, can be upgraded from 256 to 512 yes... You will need to find out what type of ram you need...\n\nto find out what ram you need use this http://www.crucial.com\n\nit will ask you for your make and model, then tell you what type of ram you need. It will also give you prices, but dont buy from them, just write down the type of ram, and search your local stores for it...\n\nIf you wish to buy it online, try http://www.tigerdirect.com or http://www.newegg.com

Yes, all laptops these days come with the ability to add/change RAM.  On the Toshiba's, there is a little door underneath that has to be opened (it's got one screw to keep it from coming open when you didn't want it to).  \n\nAlso, you don't need to buy the same brand of RAM, they are all compatible, you just need to buy the same speed & type (DDR or DDR2, PC3200 or PC2700).  Although, if your laptop has PC2700, you can almost always use PC3200, since you would be running it slower.\n\nHere's a link to quite a few SO-DIMMS (laptop memory): http://www.newegg.com/ProductSort/SubCategory.asp?SubCategory=381

If you are not sure about which RAM you need, or you do not know your motherboard model, then you can do a system test at  - \nwww.crucial.com\n\nIts called system scanner, the link is here - http://www.crucial.com/uk/systemscanner/\n\nThis will identify your system and give you all the compatible/available options to ugrade..\nIts a nice tool, obviusly you dont need to buy it from there..... you just need to find out what you need..........

Yes upgrade the ram if you can get a really good deal on some used ram sticks. Otherwise consider upgrading to better system. I sell better used systems than this for what it would cost you to upgrade using new parts.

Bogus dude has it right.  Use crucial.com to find out how many RAM banks you have.  Then as a suggestion, use their part numbers then go to newegg and order those part numbers from them.  You can buy ram anywhere so...\n\nOn a secondary note, you could try to match your RAM, you mention you are running 128 of pc2100 and 256 of pc2700.  It would be best if you ran the same types of ram in all your banks.  They even have matching ram sets that run at double data rate.  Currently your ram is dumbing itself down to pc2100 speeds.

After looking up your model, it only supports a MAX of 160MB of RAM.  That's not enough to run Windows 2000 or XP and for it be relatively usable.  In addition, you will need several GB of free space to install.  I recommend you look into a new laptop, even Dell has ones that are only a couple of hundred dollars that are better and will cost the same as the upgrades you would have to consider on your current model.

You have not stated WHAT ram slots your Motherboard has.\nGuessing by the PII 333, I would say SDRAM, the older style.\nThe newer style, DDR ram, is able to use 2 cards of ram at the\nsame time - one can read, the other can write, so that 2 cards\nof identical ram will add speed to the motherboard ram system.\nSDRAM will not add speed to your ramm system by using two identical cards - MORE ram will certainly help.\n You really should find out what the motherboard is, and go on the website to the manufacturer ( ASUS, etc. ) and get the manual PDF file, and read what ram your computer uses, at what speed.\n ( All ram comes in sizes, and SPEEDs, so that you would waste money buying faster RAM speeds than your motherboard can use ).\n The SDRAM and the DDR ram slots are slighlty different, and\nsome newer boards have both - SD is usually about 3.3 VOLTS\nwhich is clearly, but microscopically written on the edge of the ram plastic holder, about the middle of one edge on the top, and\nthe PINS are marked clearly, but microscopically on the ends from 1 to 168 pins. The DDR, is usually about 2.1 volts, and again, is clearly but microscopically marked on the plastic...\n Don;t buy any ram unless you first find out what ram sticks are allowed by the motherboard, and exactly what speed is allowed.\nIf the motherboard only sees 3 , 128 meg, PC100 ( speed ) ram\nsticks and you buy , 3 , 256, PC 133 sticks, your motherboard can happily "see" 3 128 meg sticks ( and stop counting ), and\nstate that they are running at PC 100 speed ( that is all the motherboard can do ), and you are wasting a lot of money on\nextra ram and speed that you are not using!\n There are other issues with ram, in that there are hundreds of manufactuerers, and although the amount ( 128 Meg ) and\nthe speed ( PC100 ) may be the same, the manufactuerers \ncan arrange the ram chips on 1 or 2 sides of the chip, in sets of 2 BIT rows by 64, 4 bit rows by 32, 8 bits by 64, etc. etc. and the\nram card you buy may not work in " YOUR " computer, even though it meets the Size/Speed requirements.... \n I often take the tower into a computer store, put it on the counter, and ask the salesperson to put in the ram I am buying, and\ntest it on a monitor. Sometimes I have to get 3 sticks of ram to find one that actually works...  \n Some salespeople actually build the units, and know as a rule of thumb, the "kind" of ram that fits a certain motherboard, but the best bet is to actually try the ram in the first place... There is an\nexception to every rule...\n\nHope this helps\n\nrobin

Yes, you can upgrade your memory and if it's only 512MB I'd recommend you do. 512MB is okay for now but if you want your laptop to work fine for the long run, upgrade to 1GB or maybe even 2GB. Just check to see if the RAM cards are compatible with your laptop beforehand.

That depends on two factors.  One, you have to know how the memory modules are populated on that notebook, do you have two 256MB modules that you can replace.  Do you have one 512MB module and no extra slots.  Or do you have the kind that has 256MB integrated into the motherboard and only one module that can be replaced.  Two, it depends on what kind of memory you need for it, I mean yes, you need a SODIMM but what speed, some type of DDR or is it DDR2.\n\nThe only thing I can reccomend based on your question is for you to head over to the Crucial Memory Advisor, http://www.crucial.com/store/listmfgr.asp?cat=RAM and either run the scanner or enter your manufacturer and model number to find the ram appropiate for you.\n\nOnce you know what you need, find the best prices on the ram at Newegg, http://www.newegg.com/

just open your laptop and bring it to frys or best buy and ask for the ram you want and show them your system...just plug it in where the long boards on the main board are plugged in...it's that easy really...
