We bought around 40 of these X220 I5 before xmas and now more than 20 of them have failed. The company we bought them from tried everything but they ended up switching the mainboard on the first two that failed.
We were told it was a batch issue with the serial number R9-HNXXX and now all of those are changed into T420. But today we had the same problem with serial number R9-HXXXX that was bought two weeks earlier and with different config - I7 and SSD.
The battery on it flashes 3 out of 5 lights but not in order. The two end lights and the middle light comes in. They flash in unison 3 times before turning off. Anyway I plugged in 2 different chargers to the computer and the battery light on the pc flashes 3 or 4 orange and then 1 green. Then it resumes the light cycle just mentioned. The computer gives ZERO response to this whatsoever. If I unplug the ac adapter, the computer turns on for four seconds. No hdd noise, no fans, just a green power light ONLY. Not sure how to fix this or what it is, but nobody in the forums or on youtube or google seem to have solutions or even the same issue. I have tried reseating both ram, unplugging the wifi chip, dvd drive, doing the 20 second power drain without battery hooked up. All the same responses, just nothing....
I connected with the power plug and there was no green/yellow light next to the power socket. It seems not charging at all. Now it is forever dead. Tried to take the battery pack off, and connect it directly power plug, still dead.
One of my users brought me this issue the other day. He is using a Latitude D830 laptop with a D/port docking station. With or without the laptop docked, The power button on the docking station flashes Orange and Green when powered. I've swapped power bricks for the dock. The laptop still seems to charge while being docked. After swapping the dock, the new dock is fine.
What might be causing it? Is the dock dead? Could it be a failed port on the docking station?
I have an Acer Aspire 7740-6656 that shows no signs of life. I have tried removing and replacing the battery as well as trying different locations to plug into power. I have even tried removing battery and power supply and holding start buttom 30 seconds. Except for a green light on the power supply cord, still no signs of life. What if any are my options?
My laptop wont turn on, whenever I press the power button all the lights light up for about a second, I here the fans turn on and then it shuts off. When I plug the charger in the the charger light blinks, but thats it.
I have a major problem with my hp pavilion dv6-3143sa laptop.
I put it to a shop and they told me it was a motherboard/cpu problem and they couldn't source parts. I managed to get the parts. I put the motherboard first, but didn't work. I then added the cpu and put on thermal paste, but still didn't work.
My laptop will power on but I'm still getting a blinking light on the caps lock button and a black screen.
When I turn my laptop on, the blue light on the power on button lights for 6 seconds, meanwhile the led near the power plug on right side rapidly blinks 13 times. Always exactly 13 times, so it must be some kind of error code. Then laptop shuts down. Nothing is heard, neither fan, neither hard disk.
I have a Dell Studio 1558 laptop which is currently four years old and out of warranty.
Currently, with or without the battery with AC adapter connected when I press the power button, the power light does not light up but the battery status light keeps on blinking until the power button is pressed. I don't see any boot up screen or hear any sound of CPU fan running in the mean time. Basically, it does not start at all.
I recently got new dell authorized battery as a replacement for laptop fearing that could be source of problem. However, the new battery does no good. I checked the battery health and status and its fine.
Before this issue the laptop would start and immediately on boot screen it would shut down. So, I got it fixed from a repair service center who cleaned up the clogged cpu fan. It worked fine for two days and then the issue resurfaced.
Now, it does not start at all. I even checked with another adapter and also changed the CMOS battery (as date and time kept changing on every boot) but the issue still remains.
Also tried removing and reconnecting the RAMs one after another and then trying to boot. Also tried draining the static charge if any after removing the battery and adapter and then holding the power button for 50 seconds. Reconnecting with ac adapter with or without battery then also does not start the system.
I have an SR290 and recently I had a problem with the wireless. The wireless switch at the bottom left corner does not seem to work; when I move it to the ON position, the LED does not light up green to say that it is working. In the Device Manager, the wireless device does show up, and I can disable/enable it, and it indicates that the wireless card is still functioning. Under network connections, the network connection does show up, but it cannot detect any wireless networks. My other devices can pick up the wireless signals.
The probleme is that when i plug the charger into the wall, there is a green light on the charger. As soon I plug the charger into the laptop, nothing is happening (+) plus its flicking off the light on the charger
I tried several DELL charger and it did all the same senario.
I have had my TZ for a year and 2 weeks ago the power button wont switch the laptop on, when i push it just wont turn on. (nothing to do with the battery). i sent the laptop to sony and they told me it would cost $900 to fix, so i said no way im going to pay that much. so i am now stuck with the TZ, is there an alternate way to put the laptop on?
I have a Latitude E6510 that will not start. When pressing the power button, the power light goes on for about 5 seconds and then turns off. I also notice the battery light flashes a few times when re-connecting the AC adapter.
Removed the battery, held in the power button 30 seconds, but still not working.
We have had this laptop about 6 months. About a month ago, it exhibited this problem. After talking to Dell Support, they recommended a system board replacement. The laptop was sent in and the board was replaced. When I got it back and tried to start it for the first time, it did the same thing. I then pressed the Latitude "ON" button, and the laptop started.
Now it is doing the same thing, and I find it hard to believe that another system board is bad. I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode. Or maybe it is just trying to get into "ON" mode.
I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem. Again--I find it hard to believe a second system board could be bad.
My mute button is Orange & i can't get it to go back to green or blue when i touch it I get no sound at all On the bottom right corner where it shows the volume when i touch the mute botton it shows mute then on but orange mute button dont change back to blue or green in color so volume will work
I have a Dell E4310, about 2 years old. When I connect the charger just to a power socket the green light on the charger comes on but when I plug the other end into the laptop the green light on the charger goes off, I have taken the battery off the laptop and it still does the same thing, and in both cases the laptop will not power up and no light appears on it.
I know that in the power options you can change what pressing the power button does, but "lock" isn't an option. Before I upgraded to Windows7, I discovered how to set this but I can't figure out how to do it anymore.
Okay so my first question is this: Right now my wireless light is on showing that it's wireless, but if I close my laptop, or if it goes to sleep, and then I go back onto my laptop the wireless stops working and the light is off and it won't go on when I move the switch. I have a Aspire 5590
My second question is: I've hooked up a second monitor to my laptop I checked the settings and it works like this, if I move my mouse to the right and keep going, my mouse appears on the second screen. How can I make it so that the start menu and everything goes from the first to the second screen that way I can close my laptop, cause if I close my laptop screen it disables the second screen also/
I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.
