Depending what type of phone service you currently have. You can call Asus tech directly. M-F, 9:00AM to 5:00PM. EST
At: 1-812-282-2787. It will take about 2 minutes to get connected with a tech (The people who do repairs on MB's). Give them the location of the capacitor & motherboard model number.

Good Luck!

Amp light not working and one dead right channel


Without knowing how it's actually laid out, I'd surmise the output amplifier transistors in the right channel are shorted, the fuse for that channel may be blown, and the speaker protection circuit is keeping it turned off. Most amplifier speaker protectors disable both channels if there is a problem, but yours could be different. I surmise the lights you mention are directly connected to the speaker protector chips and indicate readiness for normal operation. If it takes a few seconds for them to come on after power-up, that lends credence to my hypothesis.
Unplug the amplifier, open it up, and measure the resistance from the right channel output to each of the output power supplies (or to the fuse for the output power supply for that channel, if present). If one or both is very low (i. e, close to zero), you have a fried transistor. If that is the case, it is probably a good idea to replace the complementary transistor connecting the speaker to the other power supply even if it tests good; it may have been overloaded when the first one shorted. In many amplifiers, the transistors are inside a hybrid amplifier module, so you would have to replace the entire module. In some amps, you have multiple transistors in parallel; here you can probably keep the transistors that were in parallel with the failed unit, but I'd still recommend changing the complementary transistors.

How to install 2gb ram in acer aspire one D270-1375


Turn off power and remove battery pack and make sure it is not plugged in. Remove screws from back panel exposing RAM ports. There will be two spring clips that can pushed out to release the ram modules. Remove the old RAM modules and insert the new Ram modules in reverse order and assemble netbook. Power Up and enjoy.

Add ram Satellite u845


Power down your Toshiba Satellite.

Unplug it from the wall.

Turn the machine over and remove the battery.


Locate the RAM compartment cover, which is usually located somewhere in the middle of the underside, and is about 4-by-4 inches.


Unscrew the RAM cover screw with a Phillips screwdriver and set aside.

Ground yourself by touching a metal object.


This will release any static electricity built up in your body, which can harm computer chips and components.

You can also use an anti-static wristband while you are working.


Remove RAM modules if needed.

This is most likely if you are upgrading the present RAM capacity with a larger RAM chip.


Press your fingers on the clips on either side of the chip to pop it out of the socket.

Pull the chip out of the RAM compartment, holding it by the sides of the circuit board rather than on the chip.


Insert the new RAM module into the socket. Align the RAM module so that the notch lines up with the tab on the side of the socket.

Gently lower the module into the socket. Press into place with your fingers.


Replace the RAM compartment cover. Insert the screw and tighten.

Replace the battery and secure with the lock.


Plug the Toshiba Satellite laptop back in and power up the system.

The upgraded RAM should be automatically recognized.


hope this helps

My laptop will not turn on but i know its not a dead battery


Just check the ram memory ..cause this is about the only thing you can check without opening it completely ..if this is not the case it is probably the CPU ..cause if it was the mother board it would not indicate the power at all ..
To check the ram memory ..remove all modules and place them back and insert well to be sure it makes a good contact ..but never handle directly but from the ends..(static can damage them ) ..if there are more than one modules ..insert one by one ..and even if it not boot to windows ..just see if it does boot to BIOS by pressing F2 on start ..if it works ..it means you need to reinstall operation system and will work ..
if you do have something on screen at start it may be the fault from the hard disk ..so if you get to go to bios ..also check the hard disk to be detected..and if it is on sata ..disable the ahci function for it ..and see if it runs ..
Good luck !

My system doesnt see the ram i installed,(512x2) its perfectly compatible,still it only sees 448 MB out of 1024.i updated bios and everything.is it coz i am using the on-board graphics adapter?help me out...


It looks like your computer is seeing only one 512Mb RAM module. Your computer uses shared RAM - 448Mb RAM is available for the computer and 64Mb is reserved for video RAM (448 + 64 = 512Mb) of RAM.
One of the RAM modules may be faulty. To determine which RAM module is faulty, remove both RAM modules and insert one RAM module at a time to determine the faulty RAM module.
If both RAM modules are OK then -
Some computers do not like mixed RAM modules from different manufacturers. Try using the RAM modules with the same make and type/speed.

I replaced the memory and turned the computer on and no video. no beep either.


Assuming you tried putting the old ram back and had the same result?
No beeps are indicative of a failed Power supply (check the PSU fan is working and the CPU fan is turning), Then check the ram modules are firmly inserted. Check the small 4 pin Black and yellow power rail that powers the cPU is tight.

After that, unplug, remove the CMOS battery, leave for 30 seconds and re-insert, try booting now.

If that fails, you have either got a fault on the mobo, or a dead CPU.

Testing the board with a known good CPU will confirm the latter.

Check the motherboard for blown and bulging capacitors, see if you can smell any burning from the board, either will indicate damage to the motherboard

Post screen scrambled, seems to be temperature related. I.E. low temperature, scrambled screen-warm temperature normal post screen. desk top pc, GA-MA790GP-UD4H, AM2 Quad CPU,4Gb Ram,GeForce6645 Graphics,...


Looks like an electrical contact problem. Try pulling out and re-inserting all the removable elements, especially the memory modules. When you instert them, make sure to push them firmly into their sockets until the side latches click in place, and wiggle every module gently to make sure it's properly seated in the socket.
If removing and installing back memory and expansion cards doesn't help, it may be a broken track on the board, a problem with some socket itself (processor, memory, cards...) or some other parts on the board, like capacitors, power transistors or such.

Its like the reverse band needs adjusting so make sure tranny fluid is clean no bunt smell
if its discolored or smells burnt then its clutches & bands!

Beeping on start up


Your motherboard has 64Mb built-in RAM and the video card needs some video RAM and has grabbed 8Mb of RAM which leaves the system with 56Mb of RAM. When you insert a 64Mb RAM module you have a total of 128Mb of which the video has grabbed 8Mb which leaves the system with 120Mb.
You can't change stop the video card from grabbing 8Mb of RAM, the RAM is essential for the video to work.
You can upgrade the RAM by removing the 64Mb RAM module and insert a 128Mb or 256Mb RAM module. You may even be able to insert a 512Mb RAM module if the motherboard will accept it, you need to check the specification of your laptop to see the maximum amount of RAM the laptop can handle.

CB keeps blowing fuses


There are a few common reasons the fuse keeps blowing:

1. The transmitter final transistor is bad, it usually is directly connected to the 12v source and not switched by the power switch.
2. The power wires were accidentally reversed I.E. positive to ground, neg to 12v. There is a protection diode on the circuit board that did its job and is now shorted. it will keep blowing fuses until its replaced.
