My Lenovo 0768-A53 will not power up

Try removing the battery. Then while battery is out, connect a power chord and turn it on.

I have a hp6735s i got a new battery and it turned on for all of 2 mins then went of its bin charging for about 10 hrs and blinks half ornage half blue but wont come on at all .. the ac adapter voltage is...

The Genuine Battery for this laptop is:
(HP: HSTNN-IB51, 451086-361)
47WH 10.8 Volts

Adaptor sounds right also, though its not the volts that count ( give or take 0.5 volts each way) but the amps that matter, guess your charger will be a 3.25 or 3.65?Amp if its a genuine charger?

The actual problem could be down to a few things:

1.) Check the adaptor, see that the LED light on the adaptor is not flashing green, it should be steady. if in doubt, try a new adaptor or a borrowed one if possible. An adaptor that looks ok, may also fail under load.
2.) Check the DC jack port and see if the centre pin is loose, if it is, the DC jack will need replaced in the laptop.
3.) with a toothbrush or similar, clean the metal fins in the battery bay that the battery locks into, good contact here is important to the batteries ability to charge.

My ibm think pad t40 is not switching on

Assume you are trying this on battery and mains?
1st thing is to check if the AC power adaptor is giving out any power, which you can do by obtaining a multimeter and setting it to 50 volts DC. Place the positive probe in the centre of the adaptor plug and the negative against the outside of the adaptor plug and see if you get a reading. this will confirm that there is power getting to the laptop

(NOTE: THIS IS TO BE TAKEN FROM THE DC END of the power adaptor NOT from where the kettle lead AC source enters the adaptor.. if in doubt, get someone who is competent with using a meter)

2nd, is to check that the power button is not sticking and that the small plastic pin between the laptop body and the screen ( I think these have one) is not stuck, preventing it booting

3rd, If you are getting power by AC to the laptop, check the condition of the DC jack socket, if it is loose, appears to spark whrn the jack is plugged in or crackles, this will need replacing

4th, If the above do not work, it is possible that the main fuse in the laptop has gone...specialist repairers job.

Laptop will not power up.

  • If possible, make sure there is power coming from the power adaptor with a voltmeter. If nothing shows, the adaptor needs replacing or repairing.
  • Try removing the battery and running on the power adaptor alone. If this works the battery is dead. You can buy a new battery or just run it on the adaptor.

Bios stuck on my toshiba L305D-S5934 it not doing nothin when pressing F2 or F12 but CTRL/ALT/DELETE then it just restarts.. i took out RAM, then computer will not boot up replace ram one at a time bios...

u can re-set the BIOS by removing the BIOS battery, the BIOS battery(wrist watch cell) is the size of a Dime inside the laptop, so you need to open the laptop, i suggets you visit a technician to do this.
Try doing the following also.
remove the power adaptor and remove the battery from the notebook, keep pressing the power button for 3 - 4 mins. Refit the battery / power and re-start.

Ac power light does not come on

Probly the ac connector has came loose from the motherboard. It's quite common on these models.
It can be re-soldered (possibly) and requires the board taken out completely.
Good luck

Below is the URL for compaq's Service Manual for that model. This shows you the details of every single part & how to disassemble and reassemble every screw. Surely it has to be in this document, somewhere. -->

Wont boot no BIOS and oly a white screen

Typically I have found that it is a connector that is the problem. You're getting power (lights the screen) but you aren't getting a digital signal (Screen Memory Map & Desktop). Check the mylar ribbon cable on the left, that is going under the hinge. Upon close inspection I found mine had cracked connections. A quick dab of solder corrected it. Not allowing the iron to rest on the mylar long. If you have one of the older models, and using a pin connector, check the leads, and make sure it is seated correctly.
