My T60 cannot shutdown, hibernate and standby

[Dermis]

Hi to all thinkpads community family,

I,ve been facing some strange simptoms with my T60.
I'm using win xp pro. The problem is my T60 cannot be shutdown,hibernate and standby like normal. Everytime i tried to shutdown/hibernate/standby, my T60 will reboot after a few seconds of power cut-off.

I've been googling and tried to disable windows automatically restart if failure occur but it still restart and restart and restart
Im confuse whether this is hardware problem or OS problem

Can anyone help me? Sorry for my bad english

Hello:

Since our group has no idea as to the age, condition, or programs loaded into your t60, or if your system has corrupted files, I would begin by restoring back to ground zero.
(Back to factory Installation). After this, load all the updates via the Lenovo site. Also, since I didn't mention it, make sure your bios is up to date.

Once you have your system back to it's original configaration, see how it runs. If this fixed the problem, GREAT ! If not, we can take it from there............

Before restoring, back up and important files you may need for future use.

Good luck and hope things work out.

Thanks for your concern.

I've already update my bios to 2.19 (79ETD9WW).

I've also has restore my t60 to its factory setting but the problem still occur, my t60 still restart instead of shutdown/standby/hibernate.

owh, before i forgot, when i tried to set my system into standby mode the 'standby light' did not appear. All the status light off. Then after a few seconds the system restart again with a beep sound. 1 long, 3 short, 3 short, 1 long beep. Are there any clue with this beep sound?

Any help and ideas really appreaciate

Consider looking at the following from Microsoft Knowledge Base:

Windows XP restarts when you try to shut down your computer.

Windows XP restarts unexpectedly or restarts when you shut down the computer.

I have the same issues listed here with a T60. Has anyone found a solution? I have tried a new keyboard - no help.

When you see the ThinkPad splash screen during boot: press F1 to enter BIOS. Disable Wake-on-LAN in BIOS if it's an option.

In Windows Device Manager:
for the ethernet card: disable Wake-on-LAN,
for the wireless card: disable Wake-on-WLAN.

It was motherboard faulty. Replace it then everything will be back to normal.

Hello.

A few weeks ago I purchased a used T60p 2007-YS3 on eBay. It was not exactly what the seller digitalintl (http://stores.ebay.com/digitalintl) has promised to me. Stay away from this seller. The computer I received has a dim display, worn out plastics and keyboard and is overall in a quite poor condition. However, at least at first it seemed to be functional and it was even perfectly possible to install the operating system without any problem. The surprise came later. It turned out that it is not possible to shut down the computer. After a complete shut down it turned on again a few seconds later, regardless whether it was powered by a battery or by a power supply.
Frankly speaking, I was not exactly in a good mood discovering this strange symptom. My worst fears came true after I determined that this behavior is not operating system or driver dependent, since this was happening not only under Windows XP but also under Linux. It became quite obvious that there is a hardware fault.
Luckily I managed to get the schematics of a quite similar motherboard and tried to figure out what might be wrong. Pretty soon it became clear to me that most likely the problem is related to the power management chip TSURUMAI-2, which is in my case Toshiba TB62506FG. Unfortunately I was not able to find a datasheet, therefore it remained more or less a black box to me. However, I had a strong feeling that the dynamic, i.e. AC coupled circuit, composed of diodes and capacitors, and connected to TB62506FG’s pins 36, 37 and 38 has something to do with the problem. It is quite likely that the role of this circuit is to monitor dynamic changes on the main power supply line VINT20. If these dynamic changes are not transferred to the TB62506FG correctly it may well be that TB62506FG after a complete shut down responds by turning on the computer again.
What I did in my attempt to fix the problem was the following: First I dismounted the laptop to get the motherboard out of it. Then I identified the location of the TB62506FG. After some inspection it turned out that in my case the circuit connected to pins 36, 37 and 38 is not exactly the same as shown in the scheme1, since there is only one 1.5uF capacitor, connected to pin 37, and one diode is missing. The latter is replaced by a 0 ohm resistor. Pin 36 is not connected at all. Both capacitors, 220nF and 1.5uF are located in the close vicinity of the pins 36, 37 and 38 on the top side of the PCB. Diodes and the 0 ohm resistor are soldered on the bottom side of the PCB. I removed the capacitors and checked their capacitance. Although it turned out to be within tolerances I substituted 220nF capacitor with a new one and, since I didn’t have one at hand, swapped the two 1.5uF capacitors as shown on the picture Top1. Then I continued on the bottom side of the PCB (picture Bottom1). I checked the diodes with component tester (Hameg 204-2) and RESOLDERED all components within the ellipse on the picture Bottom1.
I assembled the laptop and checked its shut down behavior. It was fixed. When I shut it down completely it doesn’t turn on again.
Since I did several things at once I can’t really say what the exact cause of the problem was.

Welcome to the forum.
I cannot quite agree with your opinion of DigitalIntl, I've dealt with them several times, and always received very-good to excellent laptops, incl. several T60p machines.

Apart from that, interesting observations about the power circuit.
It's possible there was a liquid spill on that motherboard, and your soldering "cleaned/fixed" that.
Unfortunately you forgot to put in your photos (or a link to your photos), any chance to still attach them?

Hello,

I was trying to attach three pictures, but unfortunatelly with no success.
Can you give me some instructions?

[RealBlackStuff]

If they are your own pictures, you need to upload them to a (free) website like: http://www.imageshack.us
The instructions are on the website.
Once the pictures are there, they give you the coding to put on a forum so other people can see them too.
