Blood damage to switches

Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} Little over a year ago I purchased a severely damaged notebook from a Cameroonian refugee and found that there was more blood in it than any other electronic device I've serviced, including a dialysis machine. This is likely from the original assembly of this unit clearly the blood under the screws was not disturbed by prior repairs. And there were no marks from other work under that blood. (Also gauze bandage found under heat pipe assembly w/ original undisturbed galvanic rust.)

The gore washed out okay, however the switches (on/off, internet, sleep, etc.) are badly corroded. And while I have cleaned the rust out of power switch the contact finish is now raw copper alloy.

Seeing as gore in Compaq/HP products seems to be common place (at least in southern Ontario) I have to ask three questions:
1) Is there a remedy for preventing the corrosion from spreading such as a recommended mineral oil?
2) Would I be better off to replace the switch plate (all switches rusted) entirely?
3) Am I the only technician who is finding human gore instead of dead critters in recent years?

    In this laptop the blood is human, I think;
    I suspect that some assembly worker got a finger caught on the sharp movingheatsink backing, and later (after being bandaged up) suffered a repeat injury.
    I did spend the money testing this blood to verify its origin, or if it carriedany diseases; I just used the solvent, same as I would with any mould filledmachine.

    I've not noticed significant corrosion spread since posting, however I amgreatly alarmed by the amount of gore I am finding in 'refurbished' and 'unbranded'HP/Compaq product; organics contamination interferes with the proper electricalfunctioning of most electronics and with this becoming commonplace I wouldthink that there would be an agreeable remedy for this.

    Other HP gore I've delt with discovered in the last three years include:
    lizards and other small animals crushed in the 'skis' of BX workstations (lotfrom "HP-Approved" reseller, multiple units)
    roaches (only once, kiosk)
    dead mouse? (only once, different kiosk)

    When you say blood, do you mean human or animal?

    This laptop could be part of a sadistic cult. . .

I don't know if this is a sign of the times but ?????????? I'm sorry that you had to clean all of the blood out of the machine. You should replace all of the switches etc. You can buy used parts for these machines on Ebay really cheap now.

I hope that you do not have to work on any more machines filled with blood.

Testimonial: "Replacing the switches was the correct thing to do. I however replaced the switches on the board itself, rather than buy an assembled board that might work."
