upgrading mboard in HP Pavilion 4535


O

OhioGuy

Recently, my Mother-In-Law gave me her old (~1999) HP Pavilion 4535
system. It is pretty small, with just a single 5.25" bay for a DVD burner.
It would be perfect for my grandparents, who have never had a system before,
except for one thing:

It only has a Celeron 400 CPU. This thing is small - probably would take
baby ATX, mini ATX, or whatever you would call it.

I can't seem to find much of anything about it online, but was wondering
if anyone could suggest a replacement motherboard that might work in it, and
that would let me go above 1 GHz CPU, at least.

No problem with the back of the machine - I can use a dremel tool to hack
it out so that it fits there. Even if the mounting holes don't line up
right, I can just mount it with a bunch of GE Silicone II so that it is
secure, and electrically insulated.

My problem is in finding a compatible motherboard. I have no need to get
to 3 or 4 GHz - just want to get to about 3X where it is at right now. (400
MHz Celeron) Thanks!

Time to start over from scratch. You might be able to find a mainboard to
fit it, but then you'd also have to replace:
- Power supply
- Video Card
- RAM
- CPU

Gee, not much left there, is there? :) What you could recycle from that
system would be worth about $20 total, tops. It's not worth your time,
obviously. If you want to build small and cheap, you can do that. -Dave

If you want small and cheap, here is a motherboard *and* processor for $70 new.
The processor is *soldered* to the motherboard.

PC CHIPS V21G V1.0C VIA C7 VIA CN700 Flex ATX Motherboard/CPU Set - Retail
http://www.newegg.com/Product/Product.asp?Item=N82E16813185094

http://www.pcchips.com.tw/PCCWeb/Products/Productsdetail.aspx?detailid=384&MenuID=16&LanID=2

Has built-in graphics.

There are some comments here about CPU speed, and fuzzy graphics.
Since it has a PCI slot, you could stick a PCI graphics in it, if you want.

The form factor of the board is FlexATX (9"x7.5"), documented here:
http://www.formfactors.org/developer\specs\FlexATXaddn1_0.pdf

I'd probably find a nicer case to put it in.

The claimed power consumption is 50W, in the ewiz.com review.
Which means a pretty small power supply could run it. Allow
at least 100W, so you can spin up a hard drive and a CD.
