Hi I acquired a faulty eMachines d620 laptop.
Warning if you ever spill water on any electrical item
Do No Switch On!!!!
Remove the batteries if logic boards are accessible gently dry with a hair dryer.
Place the item somewhere warm for several days to thoroughly dry out.
Keep a digital camera ready while repairing items.
Set it macro mode without flash take pictures of cable layouts pictures of all items and part number labels location of screws. These will be invaluable when sourcing new parts.
Faulty eMachines d620 laptop
The fault water had been spilled over the keyboard by accident. The user tipped the water out of the laptop then switched the laptop back on it was goosed. Dead as a door nail.
By the time I had a look at this Emachines laptop all the water had dried out.
I pressed the on/off switch the display lit with a grey display, the keyboard adjusted up and down the keyboard seemed working. Plugging in a monitor to the vga port without luck.
Tried booting a system DVD. Nothing. No Power On Self Test. no beeps just dead.
The power off key did not work.
Sometimes repairing laptops there is a preferred way of dismantling.
Without a workshop manual I had a look on youtube and found a tutorial on the d627 the casing is very similar to the d620 two of the tips were very useful using a long pin to remove the dvd r/w.
Remove the keyboard without any tools but don’t use pliers as shown in the video to remove ribbon cables. You will find a clear plastic tab on the ribbon cable for this.

successful upgrade of a emachines E627 laptop from a tf-20 processor to a Turion 64 x2 1.8ghz I purchased the laptop from walmart on black friday for around 230.00 processor ran about 20.00 on ebay. Please feel free to post comments, suggestions, tips or help.

of course the cpu is an AMD am2 (ADG265OIAV4DP) on the d620 but otherwise disassembly is the same.
I removed the cmos battery to reset the settings.
After examining the mother board checking the the surface mounted fuses tested ok
These are located near the power connector unpeeling the black plastic
The legend printed on the pcb gives the amperage of the fuses.
Some water stains were found and a nose check located the faulty components
You could smell burnt components diodes and resistors and a smd chip.
After cleaning with a damp dish cloth and drying with a hair dryer the pcb looked good.
While stripped down I tested the memory in another laptop and found ok.
I checked the SATA hard disk by fitting this in a 2.5” USB2 external case.
And plugged this into my main PC tested ok

The hard disk checked out ok.
After spending over 4 hours the laptop was back together but the fault was just the same.
A look on ebay found a motherboard for £114 plus postage and this pcb was only guaranteed for 4 weeks and had no cpu.
Now it’s a case of waiting to a cheaper replacement motherboard I feel confident
I will find one sometime in the future.
One thing I should have tested the CPU most laptops I have repaired in the past use a special cpu. Looking at the photographs taken while it was in bits the cpu had a number
(ADG265OIAV4DP) a search on google located it as a low power AM2
I could have tested this in my spare pc.
Back soon
Happy computing
Tony
