Compaq 2114ea Upgrade, P4-M from Celeron?

I have just purchased a 2nd hand presario 2114ea laptop with celeron 2ghz processor and 256mb ram.

I plan to upgrade the machine with more ram, adding a 512 sodimm to the existing 256. I am also considering fitting a pentium m processor to replace the celeron. Can i fit any 478 pin processor to the motherboard or is there anything else i must check?

 

Your upgrade options might be limited by the BIOS since most OEM BIOSes dont support any other processors than what it was designed for. Given this the most likely upgrade path would be a Pentium 4 running at 1.6GHz - 2.2GHz, any higher might be incompatible as the cores were upgraded at around that time. A Pentium M will not work with the laptop.

Run CPU-Z( www.cpuid.org) It should give more details on the type of Celeron you have, this will give info on what type of Pentium 4 you"ll need since the Celeron & Pentium 4 are related.
I would suggest not upgrading the processor since it is really not worth the trouble. Upgrading the RAM & a faster HD might be the better option.

 

Ok so i cpuz'd it. I have a northwood core f27 mpga478b, so if i get a p4 with the same specs it'll work?

Then all i have to worry about is heat issues?

 

Theoretically Yes. The 2114ea belongs to the 2100 series(I think. Does it look similar to this http://reviews.cnet.com/HP_Compaq_Presario_2100_series/4505-3121_7-21271063-2.html?tag=top), if so then a P4 M(1.6GHZ - 2.4GHz) should work.[never 100% guarantee, but given the spec and the fact that other 2100 series have Pentium4-M(Northwood, 400MHz FSB, 512KB L2 cache, FC-PGA2, 478-pin) your chances of success should be higher.]

 

Ok, thank you. I know the mainboard is a HP 002a hs 570 version pq1a74, but i'm struggling to find more info on it.

 

Ok, the listed spares for it are p4m 1.9, 2, or 2.4ghz, so i'm going to try and find one of those.

 

I also wanted to check what mini pci wireless cards i can fit, so that i leave my pcmcia slot free. Is there anything i need to check for compatibility with that?

 

Be careful with this upgrade as it might be difficult to get it working 100%. HP BIOS locks(atleast with their latest notebooks) any non HP certified wireless card. This means that you cannot use any third party wireless cards. So getting a card from someone who sources from HP might be a good idea. Also these cards are particular for a series, so the card has to be specific for the 2100 series.

Another issue is that if the laptop didnt come with a internal wirless card there might not be any antennae(usually found around the LCD). So do check for any antennae before getting the card, since without that you might be better off with a pcmcia card as the range will be terrible.

 

Since my model is the defeatured one, i'm pretty sure it doesn't have the aerial, unless they leave them in and don't connect it!

You're most helpful miner, 'ppreciate it

I'm a bit confused by all these bloody processor models, i think what i need is an sl6s7, but i'm not really sure if this is correct. How do i check the intel code from the compaq part number?
Will i need to change the bios settings when i put it in?

Is there any way i can test it without frying the mobo and processor?

 

Yeah, the older the processor gets they are harder to find and also become costlier!

I think the sl6e7 should work. Is the core stepping, thermal guideline or the voltage quite similar to your current Celeron? If it is so then the chances of it working are higher.

The Compaq part number wont tell anything. It just helps in identifying the basic spec of the cpu.

The BIOS on OEM machines is pretty basic. There most probably wont be any user controllable specifications. The most you can see would be to check to see the new processor iss being recognised correctly.

Well, ther is no real way of testing cpu it without the MB! Just make sure that when you install it correcctly and that when you turn on the laptop the fan is working and check to see if the processor is being correctly recognised in the BIOS. Also check the temperatures(Mobile meter) and see to it that the processor is not overheating.
