Editing Amstrad PC9486 (section)

== Servicing notes ==

* The four SIMM sockets are awkwardly placed; ''PC Review'' found that the disc drives may have to be disconnected to reach them. Untidy drive cabling also covered one of the five slots and made another hard to reach.<ref name="pcr30" />
* The processor socket takes 486SX and 486DX2 chips and the P24T Pentium OverDrive. There is no 487 coprocessor socket.<ref name="joy47" /> Owners have fitted faster parts: one Vogons member runs a PC9486 with an AMD 486DX2-80 at 100&nbsp;MHz and 16 MB of RAM.<ref name="vog98820">Vogons forum, [https://www.vogons.org/viewtopic.php?t=98820 "Amstrad pc9486 manual."], 2024. Retrieved 2026-10-02. An owner's upgraded PC9486, and a reply placing the CMOS battery on the case near the power supply with a cable to the main board.</ref>
* The CMOS battery is not on the main board. A reply on Vogons places it at the back right near the power supply, mounted on the case with a cable to the board.<ref name="vog98820" /> Check the battery and its lead for leakage; see [[Battery Explosion, Capacitor or Corrosion Damage]].
