SOURCE: i have a gateway ma7 laptop and press power and get nothing

When the computer is off, unplug the power cord from the laptop and then plug it back in. See if the charge light (lightning bolt symbol next to the led) comes on or turns green/blue. If it doesn't your power supply may not be working, even if the light on the supply is on. Second is the battery may be damaged. Remove the battery and see if you can power on at all.
If it boots with only the cord, the battery is bad/shorted forcing shutdown.

SOURCE: LG x110 laptop power supply problem:

To be very sure of what the problem is, try to test the your laptop with a another friend's battery, or through a technician first. If it powers, then try and test the laptop again with another AC Adapter, from someone who uses the same type, or a technician.
Trying out these two things will give you a clearer and better idea of what might have gone wrong.
Hope it helps you out.

SOURCE: m-series gateway (m1629) press start button, nothing

Taken apart, looking for abnormal solder etc checked powers switches decided that this unit was acting like it may have shut down due to excessive heat issue. pulled battery on board, tested ok, re-installed everything and found that this unit now is active. Conclusion: I suspect the bios shut this unit down, hard reset correct this issue.

SOURCE: hp pavillion dv7 won't power on

Same issue - solved by disconencting everything (main battery, CMOS battery, RAM, hard disk and wireless card). Held in power button for 20 seconds (HP say this removes any electostatic charge on the main board). Reconnected everything and machine booted to Windows. Ran HP's onboard diagnostics and everything checked out OK.

SOURCE: acer aspire 7520g will not boot

Your reflowing of the mobo did the troubleshooting for you. Your mobo is bad and most likely needs to be professionally reflowed. The problem with the ACER in particular is not knowing exactly what chip is the bad one. I know for instance the chip on an HP board is usually the Nvidia chip which does many things for that system. The blanket trick works more as a diagnostic tool than actually fixing the board for good. You are probably in a position to either reflow your board or replace the thing. Good luck

How do I trouble shoot my HT-e320? The problem is, when ever you turn it on, a word "prot" is appearing and it will shut off

Your receiver in PROTECT mode has been shut down most likely to DC Offset(a damaged amplifier) That damage will have to be repaired before the unit can be reset. The repair is major, and certainly not a DIY project. If you would like more assistance, or would like to inquire about repairing your receiver, please visit my website at You may contact me there, Thank you.

Gateway MT6840 unexpectedly shut down and wouldn't

First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

Can set up th remote control for this tv with the direct tv cable remote

Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

I had my gateway fx laptop running this morning and shut it down at around 7 am. When I turned it on it loads to the log in screen but I can't type or use the touchpad at all. Help

Press and hold-down the ON/OFF button, until it shuts off. Restart it, and see if it was an "intermittent" or "once-only" problem.

If you still have the problem, take the computer to a qualified technician, for professional trouble-shooting.

Mits-WS-65712 Powers on for 3 seconds and shuts off

If you press the Input Button and Menu Button at the same time, you should see a LED flash a once or twice then pause then flash a couple more times. This is the Error Code. If you do this, it would help me determine where the problem is.
