microprocessor

Attention:

Do

not

remove

the

computer

cover

or

attempt

any

repair

before

reading

the

“Important

safety

information”

in

the

Quick

Reference

that

was

included

with

your

computer

or

in

the

Hardware

Maintenance

Manual

(HMM)

for

the

computer.

To

obtain

copies

of

the

Quick

Reference

or

HMM,

go

to

http://www.ibm.com/pc/support.

Important

Leave

your

computer

turned

off

for

at

least

one

hour

before

removing

the

microprocessor

to

allow

the

thermal

interface

between

the

microprocessor

and

the

heat

sink

time

to

cool

down.

Important

When

you

receive

a

new

microprocessor,

you

will

also

receive

a

new

heat

sink

and

vacuum

pen.

You

must

use

the

new

heat

sink

with

the

new

microprocessor.

If

you

use

the

old

heat

sink

with

the

new

microprocessor,

your

computer

might

overheat

causing

intermittent

problems.

Important

Avoid

handling

the

microprocessor

with

your

hands,

and

avoid

contact

with

the

microprocessor

contacts.

Use

the

vacuum

pen

provided

to

remove

and

install

the

microprocessor.

If

you

must

touch

the

microprocessor,

touch

only

the

sides.
