T430s won't power on - possible motherboard issue?

Q: T430s won't power on - possible motherboard issue?

I've had my t430s for almost a year now and have been basically happy with it/no issues thus far.However, this morning I went to boot it up and it's completely unresponsive - no lights when plugged into A/C, no fan whir, nothing. I've already tried the 30 sec power drain trick, verified the charger works, used an alternate lenovo charger(from a t430),removed the battery, both RAM cards, SSD, CMOS and attempted to identify the issue using the various steps recommended in the user guide, but to no avail.I suspect this to be a MB issue or possibly power socket related. Alas the laptops factory warranty expired in June as it was purchased secondhand(and registered by me after purchase). Any and all suggestions would be appreciated.

Preferred Solution: T430s won't power on - possible motherboard issue?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: T430s won't power on - possible motherboard issue?

Well, I have replaced quite a few power jacks on T420s/T430s machines, but if that were the problem, you would have gotten low-battery warnings ahead of time. When you disconnected the CMOS battery, did you let it sit a few seconds before plugging it back in? I always let it sit for 5 seconds and then I press the power button 2 or 3 times before putting it back. This drains all the capacitors. (I assume you know that the main battery also needs to be out and the machine unplugged.)

Hello all.  This is an odd one. I have a T430s that I'm cleaning up for our company. I discovered that it would power on fine when on battery without the power cord connected. When the power cord is connected, it won't come on at all. I dug into the BIOS and found a setting that had been disabled for it to power on with the power cord (Don't know why the prior user would have it that way). Now that I've changed that, it powers on fine with the power cord connected, but not when it's on battery. The power cord is fine. When I power it up it shows it's charging the battery. And I used two different power cords. Also, if I press the power button when the power cord is disconnected, nothing happens but I plug the power cord in and it immediately boots as though something had been going on but I just couldn't see it. And lastly, even when this is supposedly completely and absolutely shut down, the green light on the fingerprint scanner blinks slowly.  Does anyone have any thoughts on getting this to boot like a normal laptop and turning off that blinking light? I'm sure that light isn't a huge power drain but I'm also sure it can't be normal for this to be on when it is supposedly shut down.  Many thanks!

A:T430s won't power on without power cord connected ...

If you pull the power cord out while it is running, does it immediately die?  Are you sure the battery is good?  Is it a Lenovo or aftermarket battery?  I have seen aftermarket batteries act like they are good and charge, but really don't work.  As far as the fingerprint reader, go into the BIOS.  Under security/fingerprint, erase fingerprint data.

Power issue or the motherboard issue

Not sure where to post this so I'll put it in here. I've been building new computers for a while but i still get the occasional problem that is new to me. Just built a new system and all seemed easy enough, but after plugging the power in, yet before i pushed the power button, the power LED came on and the system fans started working.I also noticed the monitor flashing too! I was too scared to push the power button in case i fry the whole thing. Can't find any mistakes please help!

I have a computer thats acting really funny right now. Yesterday it was perfectly fine. I left for a bi8t and came back and my pc was off. No one was home so I figured maybe it installed an update and restarted or something. When I tried turning it back on: nothing. The fans didnt even spin. So I checked the power supply and the voltage readings were right on par. I tried removing componets and tried starting like that and nothing. I decided to unplug the power supply and try to plug it back in. When I plugged it back in, still nothing happened. I then unplugged the 4 pin connector from the board and tried just the 20 pin connector and the fans started running. As soon as I plugged the 4 pin back in with the 20 pin, nothing happened again. I tried 3 different power supplies(250,350,750wt) and all the same thing. Im thinking the board might be messed up? Any input or thoughts on what to try?

My PC starting having failures on boot-up which I thought might be hard drive related. I swapped the C drive for another with a clean fresh install of XP Pro but no joy.

The system loads the bios and gets past the stage where I think it says 'verifying DMI pool data....' and when the windows logo comes up it just dies. The fans are spinning but there is no activity.

I'm sure I can hear a sound like a switch going when the install dies. Anythought as to what it might be and if it might be a costly thing to fix?

Thanks a lot.

I recently bought a new computer from Dell and a new graphics card from newegg. The computer is a Dell Inspiron 545 and my graphics card is a Nvidia Geforce 9800 GT. The graphics card requires a minimum of a 400 watt PSU which unfortunately Dell only gave me a 300 watt PSU. So I replaced the 300 watt PSU with a 460 watt PSU that I purchased from a store near my place, but when my computer is shut off, the motherboard would make static noises. The noises sound like a cross between clicking/static that appear around 5 minutes after my computer has been shut down and start to fade away after an hour. The noises would only go away if I switched off the power on my PSU. I replaced the new PSU with my old PSU and the static noises went away.

The power supply that I purchased was this:

I called Dell about my problem and they said that the motherboard could not handle a power supply of more than 300 watts. I bought the computer and graphics card online so it would be a real pain to return and I'm not really fond of replacing my motherboard.

I was wondering how I would be able to get rid of the static noise.

A:Motherboard and Power Supply Issue

Dell lied to you, the motherboard has no idea on the wattage of the power supply, it simply draws as much as it needs. That said Dell's are cheap systems.

The power supply you got isn't of the best quality, and it may also be faulty. Return it for a higher quality brand and see if that resolves your problem.

I have a build that has become a nightmare! It started with an MSI B350M gaming pro mobo and I had it going well for over 6 months. All of a sudden...POOF! Nothing. Replaced RAM, still nothing. Replaced CPU, NOTHING. Replaced Motherboard, NOTHING...Switched to a Gigabyte MOBO and things went well until I tried to turn it on....NO POWER TO THE POWER SUPPLY. Tried to use another PSU from a working computer and...NO POWER TO THE POWER SUPPLY!!!! Now I have 2 dead PSU's and a giant paperweight!

Any suggestions? What would cause the PSU's to just die once I tried to power it up? Standoffs are placed correctly in the case.

Hi everyone,
I've just had an issue with my PC where i left it a while as i got engrossed in the TV, came back and monitor was in standby mode as you would expect, i moved the mouse around and nothing, it had all frozen. It's done this before and after resetting it's been fine, this time however it was failing to initialise any peripherals and the monitor. The fans were not kicking in properly and the red light was flashing in a particular rhythm. I know the mouse and keyboard werent initiliased as they both light up when on and the lights hadn't come on.
I tried switching it off completely, switched back on and same again, so i tried unplugging at the wall and unplugged the keyboard and mouse for good measure, still the same. I left it about half hour switched off at the wall and switched it back on. This time it ran and gave me a POST error stating that boot had failed and to check my settings in the BIOS. I did so, everything looked fine, so i continued. When prompted i selected start windows normally, and it booted fine, just perhaps a little slower than normal.
Once i was on my desktop i went straight to event viewer and the following events are logged right before the initial crash:

I have a gaming rig with the following stats:

500W Power Supply
9500 AMD Q4 Chip
Don't recall what motherboard I put in there, but it was functioning
Nvidia GTX 260 Video Card
1x 1TB HDD
1x 400GB HDD

In any case, there was a decently big power issue recently, and although the computer was hooked to a power strip, I'm pretty sure there was damage done as the computer will not turn on now; I can press the power button but the computer will not respond, and I went in and double checked the connections to make sure all was in working order (it was). It was in perfect working order previously, with all cables and equipment functioning, and the BIOS and everything was up to date. My issue is that I have no idea what got shot, the motherboard itself, or the power supply. Any suggestions?

Alright. I am kind of screwed at the moment so any help would be really great. Let me start this story...

So I have this desktop that was put together, and am having problems.

Some background, this desktop has had some issues for a while, with cmos errors causing me to have to clear it. Usually when I cleared the cmos the computer worked reasonably well after.

There is also some trouble when the power goes out. I believe that the mobo battery is dead, so when the power goes out it goes all wonky and I have to again, clear the cmos.

One day, after a power loss, the same problem occurred. Tried to start the computer, and received checksum error. When this happens I have to clear cmos, mess with the bios a little, and the computer will work. This time though, I was in the bios and it kind of froze. This happens sometimes, but the fix I found out was to restart and get into hte bios again, and load a profile.

Anyway, when I tried to hold the power button down to turn it off, it didn't work. So I was stuck in a frozen bios. I flipped the power supply button to turn it off. I flipped it back, and tried the power button. No go. Nothing.

So this is where my problem began. All of the other issues that I have described (checksum error, cmos clear, bios problems...) I have been able to work around before. But now I am totally lost.

After research I am thinking that my problems are the following:

i recently acquired an asrock pro 3 for a project budget build for a friend and have a query...

Basically, the atx 12v interface for the board has 8 pin holes, however my power supply has a 6+4, so

if i only connect the 6 to the 8 holes will it work?
if i connect 8 and have two pins overhanging will that work?
do i need to buy and adapter for 6 to 8 or 10 to 8?

Can you give us the exact version number / serial number for the motherboard. I can only find information on an asrock Pro 3 that shows it with 10 x 2 pins (6+4 connectors) for the motherboard power.

I have an old PC with a booting problem. I'd like opinions on whether the problem is the Codegen 300x power supply or the motherboard itself. I don't want to be fobbed off into buying another machine just yet. The machine shows the following symptoms at boot up:

1. First attempt at boot *on a cold machine*: Boots up then freezes with screen image remaining. It may take 5 minutes to freeze during which time the machine is capable of doing useful work.

2. Second and subsequent attempts at boot on a cold machine after removing and replugging power cord:
EITHER: Boots up (screen LED goes green) then does one of two things:
- a. Hangs with screen image remaining
- b. Cuts out completely - with screen image disappearing
OR: Fails to boot (screen LED never goes green)
- c. Makes several beeping sounds.

3. After about the 8th - 15th attempt at boot (when warmer?):
- d. Boots up correctly. Remains functional with no problems for hours.
- e. The box behind the power cord (CODEGEN 300W Model 300X) makes a bit of a noise.

4. Performance after correct boot: It gives me *no problems at all* for 24-48 hours at least. It can correctly operate Windows Movie Maker and will save movie files from this program which take over 1 hour to complete. There are no internet connectivity problems. It correctly reads and operates external devices such as a Seagate external hard drive, a jetflash, and a camcorder.

I have it set to nVidia only in the BIOS, However, this thing INSISTS on using the pathetic HD4000 graphics when trying to play a game. This was easy to do for the T420. Why wont this work for the T430s? What I've done:Install ONLY the nVidia graphics drivers.... I still wants to use the "generic" VGA driver for everything.It forces me to use the nVidia panel to list games for use with the nVidia graphics.

Hi, I encounter the following issues with my Thinkpad T430s:- sometimes the mouse pointer starts moving on its on, always towards the same direction and always at the same speed. Rebooting temporarily resolves the issue until it occurs again. Reducing the sensitivity in the driver software does not have any impact. Pressing the trackpoint and letting go does nothing to stop it. - the left mouse button acts like a weird combination of a left click + some function that brings up context menus, if available (e.g. on desktop). This happens using the trackpoint, touchpad and sometimes even when using an external mouse. - Right mouse button does not function at all. No matter what function is assigned to it in the driver software, it does not work. External mouse works. All this ONLY happens if the trackpoint is ENABLED in BIOS. If I disabled the trackpoint in the BIOS, touchpad and all mouse buttons work fine. I tried Windows 10 and Windows 7. The problems occur under both operating systems using different driver software. Therefore, I do believe this to be a hardware issue. Anyone has experienced this issues and knows a good way to fix it? Thanks in advance!

I have a T430s, that is still on warranty. About six months ago, I started having an intermittent problem, that sometimes when I would plug the power cord in, I would get error 0251. I would reset the clock and go about my business. This happened a few times, getting more frequent, and then one time Windows wouldn't start. We bought support when we (my company) bought the computer. The tech guy came and opened it, and said it looks like there was some liquid spilled on the hard drive (a spot a couple of centimeters in diameter). Their standard solution is to replace the motherboard, but he couldn't do that because the motherboard was "damaged". Buying a new mother board he said would cost ? 2100 (the laptop costs ? 1700). So he said it is not a warranty issue he can solve. I didn't like that answer, so we found a company to replace the motherboard for a few hundred Euros, but the error 0251 still occurred. That company took over two months to get that far, and seemed overtaxed.  In the meantime, we found a new IT partner. They replaced the CMOS battery. We just picked up the laptop a couple of days ago. I left the laptop closed with the power cable out over night. This morning I plugged in the laptop and (no surprise since I'm posting here) got the error 0251 again.  I would guess that there is:1. A problem with the CMOS battery connection causing the battery to drain.2. A short or a grounding problem in the power plug socket, ... Read more

Recently I have been gifted with a T430S Thinkpad on which I made a fresh installation of Windows 7 Home. From time to time the mouse has a strange behavior : it operates fine except to scroll in dropdown lists. I have to use the keybord to do that an select an item. When it happens the touch pad doesn't work anymore. Switching  with an other mouse doesn't solve the problem. I have to stop and restart the laptop to recover the normal behavior of the mouse. Installing last drivers from Lenovo download center had no effect. It seems other users encountered a similar issue. Some of them got rid of it after a BIOS upgrade. Infortunately  I didn't find any BIOS to download. The only files avalaibable are just utilities to install a new BIOS.

 As this is my first post,  Hello all! I'm a longtime Thinkpad user, appreciating my previous T60 and T400 for their repairability and durability.  I've just bought a used thinkpad t430s, and I bought a battery for it as it didn't come with one. My issue is, the battery worked fine the first couple times I used it, but now it drains instantly if I unplug from the wall. After I restart the machine, the battery says 0% (charging), and after a short while (10+ minutes) returns to claiming fully charged (100%). So far, I have updated the bios, installed the lenovo power management software, installed the lenovo power management driver, tried removing the microsoft acpi driver without the battery in, then turning off and trying to start on battery  (no luck turns off immediately as well, critical low battery error). I also did this thing someone recommended for battery trouble where you shut down the computer and remove the power sources, then hold down the power button for a minute. The battery health is good, it has had three charge cycles, and this number isn't going up with my little drop downs to 0% and back up to 100% whenever I unplug the machine. I would like help in figuring out if this is a problem with the battery, hardware, or software of the computer. I am running windows 7 pro 64 SP1. i7-3520M @2.9ghz. Thanks in advance!  Ryan

So the Internet on my T430s recently stopped working, and every time I try to troubleshoot I'm told to turn on wireless capability using my wireless switch, which is definitely in the on position. (I've even tried turning it to the off position just in case I'm really stupid and have them mixed up, but no Internet there either.) What I've done so far: 1) Fn+F5 gives me the message "The hardware wireless radio switch must be in the on position to use the wireless radios," which is unhelpful since it's in the on position. 2) Going into Device Manager and checking Network Adapters tells me that I have 4 adapters, and the Properties menu for all 4 says that "This device is working properly." I'm not sure which one is being used for my main connection, but all the ones listed say they're working. 3) I did some Googling and found some random sources that said you could use BIOS to override the hardware switch and turn wireless on. Wasn't able to find anything, so I'm wondering whether that doesn't apply for the T430s. Not super familiar with BIOS so I might be using it totally wrong. 4) I opened the computer up to take a look at the wireless radio switch. Didn't see anything clearly wrong with it, but I doubt I'd be able to detect a visible problem even if one were present.  So yeah, I'd appreciate if someone could help me with the issue. I'd prefer to solve it on the software side of things, so if someone could tell me a way to override the hardw... Read more

I have  bought Lenovo T430s laptop recently. The main problem is that it came win Ubuntu OS. I formated all the partition data and tried to install Windows 7. There was a "A required CD/DVD drive driver is missing" issue, where a windows prompts asking me to point the directory where to load that driver. It's on that step, where I should select where to install the drive, so I tought it was the HDD drivers. I tried with UEFI/Legacy tricks such as forcing my BIOS to use UEFI only or LEGACY only. I also tried to change the HDD options from AHCI to Compatability and many variations. Well at first time, i tried with putting the chipset drivers to usb disk and point the driver then uncheck the "Hide drivers that are not compatible with my computer" and tried to force it use my drivers. Tried with different drivers and every time I got stuck to the same problem. Then I tried with Windows 8 and Windows 10, It just installed without problem. Later I had issue with my Cooling Fan. It stoped working, So i returned my laptop to the shop, where I bought the laptop. They said that they sent it to a service and the service changed the HDD and the motherboard. The HDD was Seagate 320GB, now it is HITACHI 320GB. The motherboard is changed, because previous motherboard had Compatibility options, that was suited for windows 8, now it's gone (may be old BIOS chip/software or newer, I dont' know, my BIOS version is 2.7). So after I got my laptop back (repaired) I got it with new H...

Here's the Intel one:  https://downloadcenter.intel.com/download/25476/Windows-7-USB-3-0-Creator-Utility
You may also need to make the flash drive UEFI-bootable if that's you preferred installation mode.  That involves some file manipulation, but not a complete rebuild of the media.

I could use some creative customer service here. My M3800 shipped with the known power-on motherboard defect. It was replaced at no charge, which was very nice. However, the replacement (2nd motherboard!) is now having the same intermittent dead / no power problem.
To get the computer running, I have to remove the case (12 screws) and un-plug the internal battery to 're-set' the electrical fault. After I put it back together, the computer starts normally. This is not very convenient, especially when meeting with new clients.
The problem is that I am being told I am outside the 3-month repair warranty. I think this stinks! It's a known issue and I would like someone at Dell to step up make my expensive computer work normally all of he time.
Yes, I have run every diagnostic known to man and the internet.

It's been a while since I built a system from scratch and have a... errr... simple question

gfx: Sapphire HD3850 512MB Ultimate (passive)

MB: MSI P35 Neo2 FIR

PSU: Seasonic M12II 500W

The motherboard has a power connector for the graphic card next to the slot.

Is there any reason I should connect the power for the card to the power connector on the board instead of directly to the power supply?

A:Graphic card power to power supply or connector on motherboard?

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

Hi, I just bought an HP pavilion e9300 a few week ago. And I am going to upgrade the power supply so that I can get a new graphic card--ATI 4870 which requires at least 500 watt power supply. My current computer is shipped with a 350 watt power supply. I will probably get a 650 watt considering the 70% effeciency of power supply.
However, when I talked to an HP technician, he insisted that I could go for a power supply with no more 450 watt. Because the system I just got has a motherboard which has a max power limit 450 watt. He said if I go beyond that, the motherboard will burn out.
So what shall I do? I really want to get ATI 4870 work well on my computer.
Thx very much.

A:Does power supply with higher power rating really burn motherboard?

The long answer is "No".
Just be sure of the dimensions of the power supply before you order a replacement, as HP uses some pretty strange sizes sometimes, and you want the new one to fit with room to spare.

Hello. I have a computer I picked up from Fry's that has a K7 FSB266 motherboard, 1GB of memory, and an AMD Athlon 1800+ processor. This is the second motherboard I have put in this thing, as the first one suffered the same malady that I need help with. The motherboard is a Model M811 ATX style.

The other night we had a power outage for about 2 hours. All my computers were powered down, except one. I powered all of them back up and they worked as per normal except the one I reference above. This one was off during the outage.

Now it will not power back on. The same thing happened with its predecessor board which is why I replaced it. Am I missing something? Is there some sort of magical reset that I can't find? Why would this computer be the only one with a dead motherboard after the power was back on? Is there a flaw in its design? What brand should I go with if this thing is junk?

Any help would be appreciated.

Hello all,
Posting this message to ask for some kind assistance, and possible help. Yesterday, my electricity overloaded, causing the electricity to blow, I flicked the trip switch, and the electricity went back on. When I tried to turn my computer on, there was no response, power light didn't light up, and no sound of anything running like the fans, just completely no response. I thought at first it was a power supply, so I purchased a new power supply and tried that. When I did this, the power light, lit up, but again there was no response from the computer at all. I have tested all the components in another computer and they worked fine, graphics card, and RAM etc.,

I put a wireless adapter into the USB ports, which are connect to the motherboard, and this lit up, which made me think that the motherboard was still getting some sort of power.

Do you think it is still the motherboard? I know it will be difficult to tell for you, because you do not have physical access to the computer, but do you think this could be a possibility?

Do you think it would be worth taking the computer to a computer repair shop, to see if they could give a possible explanation to the problem?

Sorry I am not very computer orientated, that is why I have asked for your help.

If it helps, this is a link to the computer it is,

The computer is a BXB E5300 DUAL CORE 500GB 4GB RAM 9500GT 1GB PC . It can be found on Ebay, or via a Google Search.

My PC suddenly shut off and wouldn't turn on, but the mouse and motherboard lights were still on. A tech took my PC and ran some tests. I assumed that either my Power supply or my Motherboard was unfunctional but he called me back telling me that it was neither, and that the problem was coming from "a part" that gave power to the motherboard. The replacement of this part would cost $80.

Am I getting ripped off? What part could possibly cost $80 and isn't the Power supply?

Also, I have scoured this forum/internet attempting to resolved and yes there is a ton of info. The problem is the I cannot find specific details "similar" to my problem regarding how they determined the repair action, other than replaced power or mobo. So hopefully, when this is resolved this will help someone with my similar problem.

Hello All:

I have a HP DV6275US, Pavillion DV6000 with Vista Home Premium on it and I am trying to go to XP. Dual booting is too much of a ruckus and I do not like it anyways, so I bought a Scorpio to install it on.

When I installed the Scorpio, it initially would not detect the drive, so I disabled SATA Auto. in the BIOS, and it then recognized it.

So, I start to install XP, formatted fine, copied sys. files fine, but when I got to the actual GUI install it asked me if I wanted to install a driver for my battery, which could possibly disrupt installation, so I choose yes and anyways and it proceeded fine for about a minute, then power failure. Tried again, and again, and same thing.

I put my Vista HDD back in, a Seagate 160GB, and things worked fine.

I have read something about having to manually load the drivers for the nVidia RAID chipset, as the ones XP Install loads do not suffice. I could not find any problems about the battery, so please, ANY help would be greatly appreciated.

Thanks a lot.

Hi Guys,

I'm currently suffering from a random power shutdown issue. The PC boots up correctly and is totally useable and in working order.

However after different varied amounts of time. 20mins - 5 hours on occasion. The PC will just randomly power down as if the power cable has been removed.

I am getting the following error within Event Viewer 'Event 41, Kernel-Power' - "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

I have checked all power settings and have currently set to High Performance Mode, with Hard disks 'Never' to turn off etc.

After suggestions and help as to what may be causing this issue.

Thanks in advance,

If this were a desktop machine my first question would be "How old is your power supply?"
If this is the Compaq laptop shown in your specs, I am wondering if the connection to your battery is not as good as it should be. I'd double-check the contacts or connections. There may be a loose or broken wire, or even a failing connection inside the battery itself if it's old.

Hi there, I have a toshiba A75 laptop that does not boot when on ac power without a battery beyond bios. It shows the splash screen but then dies on normal boot.

When I have the battery in and the unit is powered off It does charge the battery.
When the battery is fully charged, it will run and boot into windows but does not recognize the ac power at all. It just drains the battery, then when the battery is at 0 it shuts off and this is while connected to AC power and the LED see's the AC power.

When on AC power I can boot into bios and it will sit there for days without a battery, but when I try to get to the OS it just shuts down. I have replaced the mobo twice. I have replaced the hard drive as well. The odd part is that with the hard drive out of the laptop, I can get the laptop to run with out any power failures. It just recycles the media device failure message but does not crash.

I have tested the power supply on other laptops and it seems to work just fine.

Any one have any ideas?

A:Toshiba Satellite A75 boot/power issue with AC power

Since you have replaced the system board twice, this probably does not apply to you... but we have seen a number of Toshibas with the same or similar motherboard where the power jack on the board became loose or disconnected. A new jack had to be obtained and soldered back into position.
If you bought used boards or refurbished boards, this difficult jack problem could have been the cause. It requires a special cold solder technique and is awkward to access, but when done properly by an experienced tech, it can save a laptop.
There are several Dell Inspirons and Sony laptops with the similar problem.
We have seen costs in a shop as high as $160 for this repair... but the part is only $6.00 so I don't know how they justify the high cost.

I've got a computer that's turned off. I press the power switch, and nothing happens. Now, I unplug the network cable and the computer turns on.

Why does having a network cable connected prevent the computer's power switch from functioning? And why does unplugging the network cable cause it to power up?

The computer has worked fine for a year, but was recently moved to the other side of the room, and a new switch replaced the old network hub at the same time.

Hi Again All -

For reference here I would ask that you please look at my post yesterday , the 6th at 9:52 pm, which has a sad smiley in front of the title. I finally got my computer in order and it did not turn on and off repeatedly while attemptng to load (thanks to all the helpful advice posted). However, I am in the habit of setting it at night to go to either stand by or hibernate. Last night I learned that I no longer had those options available, so I turned the system off. Probably 5 or 6 times during the night I faintly heard Bono and U2 singing away (yes, I'm delusional). Actually, it was my screensaver and apparently my computer was turning itself on. After the obligatory 20 mins. the screensaver would come on. The system must have shut down and the whole processes started again repeatedly throughout the night. This is too bizarre. I turned off the computer with the Start button and the button on the machine. I guess I have to crawl under the desk and unplug the thing, but I shouldn't have to. Can anyone think of what is going on here?


A:Yesterday's Power Problems Create New Power Issue

If you change the power settings in the BIOS, the machine won't come back on when power is lost and restored, which is the setting I always use.

Hi, Having a 90B error (fan having troubles) prior to booting up the system, I consider it a good time to clean the fan. So I completely dissassembled the laptop down to the fan to remove dust. This in order to have less sound and less heat. After reassembling it back to its original state, my laptop started with two errors. Firstly one I cannot remember (skipped to fast) and secondly the recurring 90B error. But skipping those the system started up and everything worked. The laptop was running slowly but I thought it was normal behavior. The day after, my laptop wouldn?t startup. I?ve pressed the start button and the lights went on of both the start button and speaker on/off. Immediately after that it shut down and started back up, producing a startup loop as long the laptop is feed by power (battery or charger). Anyone can help me out? If further details are needed, I will certainly provide those. Kr,JeromeBertrem
