Upgrading a Celery Lappy CPU - Help!

[Bennah]

Just recently purchased a cheap laptop. Wanting to upgrade a few things, the cpu is where Im a little stuck.

Never messed around with laptop stuff before so I dont really know what goes in what, like I do on dekstops

Anyway my current lappy has a Celery 2.8Ghz, Northy, skt 478mPGA, 128kb L2.

Its ok at speed but Im just thinking to getting something with more L2 cache really to boost performance somewhat.

Basically any northwood skt 478, 512kb L2 could go in the laptop? They do run a little hot though and might drain the battery.

Is there any mobile skt478 I could get in there, are Dothan's skt 479?

Chipset is an ATi 'ID5833' and SB is also an ATI, 'SB200'.

Thanks

Are lappy cpus not soldered onto the mobo?

Nope, dont think they are as Ive heard and pretty sure Ive seen people replacing thiers quiet easily.

Pentium Ms won't work. You'll need a mobile Pentium 4 cpu, think they're fairly hard to find now though. Something like http://www.cpu-world.com/sspec/SL/SL77N.html would work, a desktop cpu may work, never tried that, but won't have speedstep and thus battery life will suffer bad.

Ah ok thanks for that, so Im looking for a Northwood P4-M cpu then, they do drain battery's quiet bad I hear.

I might just leave it then and keep with the celery. Dont really want to bring the battery life down again.

Just a ram upgrade for me then atm.

I'l just save the extra I was going to spend on the new cpu for my next laptop. Only got another £800 or so to save

I'd try and find one on auction or used, even if you found one a little slower, from experience it would be much better than the low cache celly's...
My old laptop had a desktop Northwood in it for a bit, it was only 2ghz but the battery was still around the 90 minute mark, that was on a 2 year old battery aswell.

All comes down to how cheap the CPU is in the first place, aslong as you make sure the fans are clean and heatsinks free of dust then temps shouldn't be too bad.

I did a similar thing to a medion laptop recently - i got a 2.4GHz northy p4m for £17 inc P+P from ebay btw

I'd agree, even a 2.4 or something would perform light years faster than the slugeron in the vast majority of apps.
