First of all the battery error is with the laptop battery and not with the CMOS battery, if your saying that the light indicator for your ac adapter is no longer litting up and it would normally does, then i would suggest that try plugging it on a different ac outlet or double check if the power cord that goes to the wall outlet going to your ac adapter itself is properly plugin or seated. After you double check on those troubleshooting step and still has the same problem you could also try power draining your computer by removing the battery and unpluging the ac adapter and press and hold the power button for 15 seconds then plug it all back and try to turn on computer. If you still have the same issue after all those TS step you could try using a known good ac adapter or you could consider replacing it or might as well call their tech support hotline if your still under warranty so that they would replace it for free (Lenovo Thinkpad support: US/Canada- 1-800-426-7378, Australia - 1-300-880-917. BTW Im a Lenovo technician thats why i know this information and troubleshooting step and this what they would ask you to do if ever you're going to contact them for support, so when you call them after doing all this TS step you can just ask a replacement ac adapter for you laptop. hope it helps..

Remove the battery and AC Adapter cord, and press and hold the power button for 30 seconds. Then, without replacing the battery try plugging in your AC Adapter to see if you get any love. If that doesn't work, remove the AC adapter, reset the board again, and this time hold the power button down as you plug in the AC Adapter cord. If you still don't get any lights, you could try removing your memory, reset the board, replace the memory, plug in the AC Adapter, and try one more time.

If all of this fails...you should take advice from experts,call at-http://www.vtechsquad.com

HP Compaq 6735s Laptop screen was blank when turned on


When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.

Engine runs good until i turn on the ac and come to a stop, after a few seconds my engine dies,if i turn off the ac car keeps running.was told it was compressor,changed it & the same,has new battery...


Compressor???!!! Good god! whatever you do don't follow that person's advice again! That had to be the most expensive money you have ever saved!

It sounds to me like you are probably having trouble with your Idle Air Control (IAC). It is supposed to give the engine idle speed a little boost when the A/C is turned on to help mak up for the extra load on the engine.
Is your check engine light on? Even if it isn't you may want to scan for codes anyway because some of the codes that are related to the ide control system will not turn the light on even though they are set in computer memory.

Your IAC can be tested with a scan tool to see if it is working properly. I would recommend doing a few tests before wasting any more money on expensive parts that do not fix your problem.

No guarantee but you can try this. Remove the battery and unplug the AC adapter. Hold down power button for 30 seconds. Plug in AC adapter but leave battery out. Try to restart computer. If it starts, reinstall battery. It worked on a Gateway I was working on last week. Worth a try.

My monitor shows a blank screen .But when I press the RGB, DVI button, I can see my desktop for a second then it stops displaying. I have to keep pressing the button to change the display type in order to...


moneyshaker, Maybe your screen (LCD panel) is not blank, just BLACK!!! First thing to do is the flashlight test! With monitor connected to a KNOWN GOOD fully booted pc with WIN-desktop showing, reconnect N9 lcd to pc. Then and only then turn on N9 lcd. Note what you see or don't see!! If screen flashes on for 1 sec and goes to BLACK, then shine a bright flashlight 1" form screen at different angles and note if you see or don't see the desktop. This is only a test to check the condition of the unit's power supply and or INVERTER circuit. If you can still see the desktop even though the screen appears BLACK, then the "switch-mode-power-supply" is only partly bad. You did not state age of your unit? Most likely your problem is that the SMPS is detecting a fault in the INVERTER circuit that provides 800 to 1200 volts to light up the "cold-cathode-fluorescent-tubes" that are hung on the rear of the Clear Glass LCD panel and in front of a mirrored reflective surface. GEE wiz If I could take these long, straight, CCFT's and turn them into coils and mate them with an electronic ballast circuit called a CONVERTER circuit (ac to ac) and put them into an oversize light bulb screw-in base I could make millions.... Oh ****, That's already been done!!!! Oh! so that's how those new CFL lamps work. I suspect that your INVERTER (dc to ac) has almost bit the dirt. It will need to be looked at by a tech type person or you could visit Youtube and chcek for video clips that deal with monitor disassembly and or repair of the 2 most common LCD monitor failures. Look under "swollen electrolytic filter capacitors" and BAD capacitors, and Poor soldering and /or poor factory oven REFLOW SOLDERING and or Thermally intermittant soldering connections on printed circuit boards. This is only a guess as to what plagues you monitor. Please rate this response on fixya if it was of any help at all. im'louie12fix on fixya or lmistyrel @aol .com

Pc will not come on. Runs Hot. Will not click off.


have you tried to remove the battery and disconnect the ac-power?

then reinsert the ac-power (without battery)
and try to boot.

if that doesnt work:
remove battery and ac.
turn computer upside down. under one of the lids there will be 1 or 2 memory modules (ram). take them out
insert ac
try to start the computer (yes, without the ram modules)
leave the computer on (with black screen) a couple of seconds.
remove the ac
insert the ram again.
insert ac
try to boot again.

Toshiba Satellite 1405 - Power problem


Hi Don

Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.

Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.

If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.

Good Luck
