I was able to get a memory upgrade from memory-up.com even though Crucial, Corsair and Dell all said that I was maxed out at 512MB. Now, I would like to know if I can get a better processor for this laptop's mobo as well as a new 160GB HD (ATA-6). Since the Dell support was negative about the RAM, I am not bothering asking them.

Any ideas.

Sometimes they are... it just requires a little knowledge of the socket type... I've done several processor upgrades on older laptops from a PII to a PIII upgrade... nice improvement!

What is in there right now, a 2.2 Celery? It looks like you will need to do some disassembling to get to the cpu, and then drop in a replacement depending on the socket type/style.
 
It uses a Micro-PGA 478 pin socket, and the highest Celeron is 2.4 GHz (no real improvement there) with a fsb of 400 MHz, and a 0.13 micron die size with a 1.3 Volt core voltage and a TDP of 35W.

You could swap it with the Mobile Intel Pentium 4-M Processors that have the same TDP, FSB, Core Voltage and die size, but have double the cache built in!

The fastest you could get is the Mobile Intel Pentium 4-M 2.6 GHz. It is identical to the Mobile Intel Celeron 2.2 GHz cpu, except has double the cache!

Do not attempt this if you have experienced taking a laptop before, otherwise you risk damaging your laptop. These are just suggestions, and I will not be held accountable in case you damage your laptop.



 
Thank you for the great info. I understand that replacing a laptop CPU will be potentially lethal to the laptop and I appreciate the warning and understand the disclaimer. I've searched ebay and the internet and have not found anyone selling this CPU, SL6WZ. Do you know of someone selling it or does anyone on this forum have one they don't want?

Thanks again.
 
i thought the 1000 took 400mhz desktop processors? I know the 1100 did. If it takes the desktop processors, then a 400mhz bus P4 would work in it as well, and would be a much bigger improvement over the celeron

edit: after doing soem research, the 1000 is the mobile chips

edit 2: also after doing some more look up, it is relatively easy to replace the processor. The keyboard comes up, and the processor with heatsink is towards the top left corner with the fan being in the upper center, 4 screws holding the heatsink on.

on the bright side, the laptop isnt worth too much in the first place so its no big loss if it dies 😉

/has one, hate it, bought a T40
 
Thanks for all the great info. I haven't found an affordable SL6WZ but I did find a 2.4Ghz SL6GS that is said to work by the seller that I can afford/justify for this old laptop.

My problem now is, how do I get the laptop open. I tried a dry run, by removing battery and HD and all the screws on the bottom of the unit but there was no way I could pop off the keyboard or the top. Anyone know of any guides/manuals?

Thanks
 
Thanks for the link. I already checked those .pdf files out. Dell does't have one about opening the laptop other than changing HD or battery. I don't think that they want to provide a DYI with any info on opening the laptop to access the CPU. Any other ideas?

Thanks
 
It may be just that laptop then, I have found a couple of guides on there with full disassembly instructions. I used it to fix my buddy's Latitude D820
 
Hi, did you have any sucess upgrading the cpu in your Inspiron 1000, I have been attempting the same and although I have been able to install a Mobile P4 into the Inspiron 1000 the speed is identified in the CMOS as a 1.2Ghz cpu even though I fitted a 2.2Ghz Mobile P4, the operating system identifies the processor as a P4 2.2Ghz running at 1.2Ghz, according to what I have found out up to now it is because the P4 has Enhanced Speedstep Technoligy which the Celeron does not and I am guessing that the Inspiron 1000 m-board is designed around a Celeron processor only therefore no Speedstep Technoligy on the board, so what is happening is the processor is running as if it is on battery which is at 1.2Ghz regardless to the fact the mains adaptor is connected to the laptop, as you may be aware there is an option in the CMOS to enable maximum battery performance and if enabled and the Inspiron is running on it's battery the cpu speed is halfed to 600Mhz, I have found it pointless leaving the function enabled because of the drop in performance, although the cpu is running at 1.2 Ghz max the Inspiron still performes quite well most probably because of the extra cache and of cource it is a P4, also the battery life has improved by at least 50 percent with the P4 processor even with the crappy NIMH battery pack (around 1.5 hours) and because it's a Mobile P4 the processor is using it's Enhanced Speedstep Technoligy I have confirmed this by downloading a utility off the net and when the Inspiron is idle the processor speed drops to around 100Mhz and as soon as you give it a task it ramps right up to it's 1.2Ghz max speed and depending what it is you are doing with the laptop the processor speed continously varies between 100Mhz and 1.2 Ghz, let me know how you get on unless you have given up and if you have found a workaround to get full speed from the P4, buy the way I tried a Mobile P4 1.8Ghz processor in the Inspiron and the result was exactly the same it just ran at 1.2Ghz.

In addition to the above I originally fitted a desktop P4 processor and it didn't work I guess it's because desktop processors generally have a core voltage of around 1.5 volts and mobiles are 1.3 volts, that is the only conclusion I can come up with as to why a desktop processor will not work in the Inspiron 1000 although some laptop's do have desktop processors fitted to them.

 
I recently did the same kind of search to learn which CPU's would work in my Celeron based Compaq Presario. To get a compatible Pentium CPU, you need to know the form factor (pinout), CPU family and feature set your motherboard supports. To find out how far you can upgrade your machine:

1. Search Dell's site for your exact model number or serial number.

2. Find the link for replacement parts for your machine, and find the part number for your motherboard.

3. Do a new search for the motherboard part number.

The info on that page may list other models that use that board. If so, search for those models that use a Pentium, instead of a Celeron. That will identify the CPU family that is compatible with your motherboard.

The specs for your machine are in the Appendix of your owner's manual.

Processor type: Intel® Mobile Celeron®
L1 Trace Cache: 12 KB (internal)
L1 Data Cache: 8 KB (internal)
L2 cache: 256 KB
External bus frequency 400 MHz

Now that I've written all of that, I just found that another member recently asked the same question and got the answer you need. 😎

I was just cruising through Hot Deals and found allisolm's post for this Verge Professional Notebook Case (VBASIC17), FREE after rebate. 😎

It won't make your machine go any faster, but it may help to prevent gravity from making it go any slower. :Q 😉
 
Thanks for the info. I haven't been able to find a 2.4 Pentium 4 M CPU on eBay. Also, I haven't figured out what screws to remove and how to access the mobo. I've added Vista and it works OK for my needs. I also bought a Seagate Momentus 5400.3 160GB HD. The BIOS recognizes it, but I can't get it to boot when I put it in the machine. I've used Seagate DiscMagic to migrate my 40GB HD to the new drive, but it just doesn't work. I've tried everything.

Could you email me privately at fritzfield@hotmail.com so that we can discuss this "project" together without getting the Forums upset?

Thanks.

so much work for that thing

i got rid of mine a few weeks ago. bothering to take it apart to upgrade it never occurred to me. but i was ready to get rid of it.

fwiw, most any pentium m is going to be faster. im using a t40 thinkpad now with a 1.5ghz pentium M and its so much bettah
 
Dell laptops are generally easy to upgrade. I have had several which I have upgraded over the past five years.

Here is a link to the Inspiron 1100 parts list.

http://www.bay-wolf.com/partsinspiron.htm

The 1100 will definitely take a P4 processor - It must be a P4 Mobile 400 bus. Intel made them up to 2.6ghz. The top model SL6WZ will be hard to source and expensive. There are plenty of P4 2.2ghz around cheaply.

If the speedstep is a problem upgrade the bios.

I also run Speedswitch and 18kfanGUI which can be both downloaded free from this web site.

I have two dell inspiron 1000's. The first one i made good success with. If you can get a good harddrive, i went with 160 GB, Update the memory, Dell says the max is 524 but i use 1 gig, and with the update of the harddrive, processor (Mobile Intel Pentium 4-M 2.6 GHz) , and memory, this works great. Im a art kind of guy so i gloss sprayed my laptop case, i painted it in a shiny black with a neon green sketch, kind of like how alienware does, the laptop looks great and runs nice.

However, my other laptop. My dell inspiron 1000 (2nd) ido have a p4 dekstop processor that i will try to use and share the results.
Although im not the best at what i do i get it done. For takin it apart as i think some one said.. Look for the screws containing a (D) around them and take those off one you do that use that to pop up the panel above the keyboard( BE GENTLE!) and then the keyboard pops right up. The keyboard connect to the motherboard opens like a door. dont pull up on the film but pull up on the henge door that the film is connected to and it will slide right out. If you need any more assistant i could possibly help.

Thanks
 
you realize you just bumped a year old thread, right? 😛
i'm sure that after over a year the original poster either figured it out or gave up by now lol


 
It may not help him but it helped me a lot. I will be trying the upgrade but I
need to know how to upgrade the cpu cooler. The present cooler is only 35W
and it gets hot with the present system and will probably get hotter when
upgraded. Since the cooler is already copper, changing to copper will not
help. Is there a better unit with a better heat pipe. A small improvement may help a great amount.

It would be utterly pointless to attempt to upgrade one of these today. You would go from slow... to still slow. It would make zero difference. You're talking about going from 4.8 seconds to load a typical web page to 4.6 seconds.
