My Acer one a505 with 160 gig hd and 1 gig ram was runover on the front edge. the only datmage is the coiled resister 3R8 on the motherboard. Does anyone know how I can purchase and replace this? I am having a hard time finding the part. thanks,

Re: My Acer one a505 needs a 3R8 resistor?
Wow, the laptop was run over and and the only damage was to one resistor? I would be very surprised that you could damage a resistor and there be no cracks in the circuit board. cracks can be hard to see even with magnification. Even if you replace the broken component your laptop still might not work. If it is on a mb it is probably a small surface mount device or from your description may be an inductor. If you have no experience repairing circuit boards this may be a difficult repair to do yourself.

Should work with a processor of the same socket type. I'd seriously upgrade the psu myself. Personally I'd upgrade the motherboard and processor to a quad core, and get the fastest ram, look at ebuyer.com, you can buy a bundle upgrade package for less than you may think. :)
cpu speed has nothing to do with ram. they are completely independant. ram speed is important to the FSB (front serial bus) this is the speed at which your motherboard communicates with the devives attached to it. cpu speed refers to how fast a cpu can process info. or how fast it "thinks". most motherboards have the capability of upgrading cpu's. your mobo (motherboard will support the following cpu's:
any pentium 4 up to 3.0 ghz
it supports the following ram
ddr (nott ddr 2 or 3) up to 2 gigs (1 gig each slot) of 533mhz speed (or less)
it also supports up to 2 gigs of sdram either pc133 or pc100
you are using 400 speed ram as you stated i would upgrade to a 533 speed ram as it will be faster, but this is not necessary. as for the cpu just get any P4 (pentium 4) that is 3.0 ghz or less and it will work.
You Can Actually Upgrade This To 2 Gig Memory.
Each Slot Will Take 1 A Gig Strip.
I,d suggest Buying another 256 mb Strip, To Put Into Slot 2.
Or Buy a 512mb ( Half Gig ) Which Will Give you 750mb With your Existing Strip Already In There. ** Recommend 1 Gigabyte Max** 2 gig of Ram in This Baby Would Probably Start Glowing.
You Can Buy DDR/266/333 In 256/512/1 Gig Strips. These Are Commonly Known As SD-RAM-Modules.
As long as you have a open vga, vga e, or pci slot in your computer you should be able to install a new video card. the Acer website says your motherboard supports up two gigs of ram, I am not sure how much ram you are running but if it is under 1 gig I would consider upgrading that also. as far as a graphics card goes get one that has at least 512 mb of its own ram so it dosent pull from your system ram as I am sure your current on-board card is doing. Another couple of hints are: if you are running Windows Vista you they call for 1 gig ram for optimal performance, also it is very important that you un-install any graphics drivers before you install new ones, and when you install the new card read the instructions completely before you do anything.
hope this helps
