DV7 GETS 90B FAN ERROR CODE ONCE - DOESNT REPEAT

[LR7575]

THIS MACHINE TURNS ON EVERY DAY WITH THE 90B ERROR CODE--AFTER THAT AND MANY STARTUPS AND SHUTDOWNS 12-15 IT WILL NOT REPEAT THE 90B MESSAGE UNTIL THE NEXT DAY--     SAME THING AGAIN    --OPINION --REPLACE THE FAN OR ???

May simply need cleaning if you haven't done so in awhile. Dust,pet hair,etc can clog fan & vents. Pick up a can of compressed air. Using the tiny straw that come with it blow out all vents, ports and other openings in the case.

If cleaning alone doesn't help it might also help to do a hard reset.

1-remove power cord and battery

2-press power button for 30 seconds

3-reinstall only power cord for first startup.

4-power on

had done a blow out and hard reset, but did it again and waited one day to check if a repeat occurs--same results, 90b

error message once and then not again ---notes: doesn't get hot at all, very hard to hear running- next

It is probably showing affects of age and takes bit to get up to optimum speed when it is started for first time every day and triggers the alert. That would explain it not doing it on subsequent restarts.I would start looking into replacing it.
