Service manual for dell precision m90

Screen went crazy due to overheating because of one of the fans was not working. Took it apart a sprayed with air duster and put it back together. Now the power button will come on then go right back off. What did I do wrong?

Try installing other anti-virus like NOD32 or karspersky. You can also try to do a system restore, this may or may not solve the problem though,also using the system restore may get rid of some application you have install prior to the date you will revert it to.

Or you can try this online virus scan

http://housecall.trendmicro.com/
http://www.bitdefender.com/scan8/ie.html
http://www.kaspersky.com/virusscanner

have them scan your system (its free),that way you'll know if your computer really has a virus or not.

The M90 has 2 fans (1 processor and 1 video card) http://support.dell.com/support/edocs/systems/wsM90/en/sm/fans.htm#wp1000550
while the fans can be passing diags, the system could still be having a cooling issue. Some things you can do are:

  1. Use some canned compressed air to blow out the fan intakes and exhaust ports. The hear exchanges can become clogged with dust and debris causing the cpu or video card to overheat.
  2. The M90 video card is replaceable. If the issue is re-occurring on a regular basis, there is a decent probability the issue is the card. Try booting to the F8 Menu and run system in the VGA mode to reduce the load on the video card. If the system runs without issue in this mode, then the video card is suspect.
  3. From OFF, Hold the Fn key and press the power button to initiate diags and see if you get a diagnostic failure.
  4. Update the bios and video drivers, see if issue resolves.
If issue still occurs after all of the above, then replacement of the video card may be required

This could be a sign that your laptop is overheating. If you touch the laptop while it is running & you find it too hot, make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Hi My dell Precision T7500 makes huge fan noise constantly. It is the front cage fan and is a new original Dell part.


Edward Farren-Price,
The 2 video cards put off a lot of heat. The fan needs to run to keep the system from overheating. If the fan has alot of dust build up you may want to use some canned air to blow the dust off. You can click the link below to download the online service manual. The manual provides information on the location of parts within your computer.

Installing internal dell m90 smart card reader


You have to take apart a good portion of the laptop to reach the Smart Card Reader spot. You need to turn off the computer, unplug the AC power and remove the battery first. Make sure that you are grounded to the computer. Then remove your optical drive and the hinge cover. Next you remove the mini-card antennas either from the mini-card or their secure spot, display assembly, the keyboard and the palm rest. Then you can reach the screw for the smart card reader and the place on the motherboard where the smart card reader connects.
The full set of steps and pictures is available from the Dell support site, http://www.dell.com/support/Manuals/us/en/19/product/precision-m90 . See the Workstation Service Manual. The direct link to the English version is ftp://ftp.dell.com/Manuals/all-products/esuprt_laptop/esuprt_precision_mobile/precision-m90_service%20manual_en-us.pdf . There are multiple pages you need to follow.
I hope this helps.

My Mic in Dell Precision m90 stopped working after i downloaded Skype? Any suggestions on how to get it working again?


Have you checked the sound settings in Skype? Usually skype lets you to set your sound equipment individually rather than using the windows general settings.

Especially if you have onboard mic. Try the call settings sound options in skype and check to see if it is working.

Dell precision m90 overheats randomly


Either your motherboard has gone bad, or you fan AND cooling grid needs replacement. The grid is simply a series of metal bars, so to speak, which absorb heat to be passed out of your system with the cooling fan. The cooling fan has 2 speeds. If the system is not kicking in the higher speed on the fan, it's more than likely a bad motherboard. Also, make sure you keep your laptop plugged into the wall as much as possible. Going on battery alone does slow down the processor considerably to conserve the battery.

Best wishes.
